PDF version As a scientific productive activity, engineering is closely associated with natural science on the one hand and industry on the other. The emergence of chemical engineering was influenced by the America’s industrial structures and academic institutions. The science-oriented characteristic of chemical engineering in turn impacted the development of industrial structures, especially the rapid rise of a competitive petrochemical industry.

The paper surveys the origins of chemical engineering in England in the late nineteenth and early twentieth centuries. It deals particularly with the recognition of the field as an independent discipline, its relations with chemistry and mechanical engineering, and the influence on its growth of industrial ‘demand’. The position of chemical engineering in public discourse, in the City and Guilds Central Institution, and at Imperial College of Science and Technology and University College London are discussed, (...) together with the creation of the Institution of Chemical Engineers in 1922. The idea that the discipline grew merely in response to the demands of industrial capitalists is rejected, and a variety of other interest groups is shown to have participated. (shrink)

Models underlying the use of similarity considerations, dimensionless numbers, and dimensional analysis in chemical engineering are discussed. Special attention is given to the many levels at which models and ceteris paribus conditions play a role and to the modeling of initial and boundary conditions. It is shown that both the laws or dimensionless number correlations and the systems to which they apply are models. More generally, no matter which model or description one picks out, what is being modeled (...) is itself a model of something else. Instead of saying that the artifact S models the given B, it is therefore better to say that S and B jointly make up B and S. (shrink)

Chemical engineering - as a recognised skill in the workplace, as an academic discipline, and as an acknowledged profession - is scarcely a century old. Yet from a contested existence before the First World War, chemical engineering had become one of the 'big four' engineering professions in Britain, and a major contributor to Western economies, by the end of the twentieth century. The subject had distinct national trajectories. In Britain - too long seen as shaped (...) by American experiences - the emergence of recognised chemical engineers was the result of professional aspirations and contingency, and shaped by a shifting ecology of institutions, firms and government. Drawing upon extensive archival research, this book examines the evolution of technical practice, working environment and social interactions of chemical engineering. It will be of considerable interest to historians, sociologists of the professions, and to practitioners themselves. (shrink)

On the origins of British chemical engineering,.

The emergence in Britain of chemical engineering, by mid‐century the fourth largest engineering specialism, was a hesitant and drawn out process. This article analyses the organisational politics behind the recognition of the technical occupation and profession from the First World War through to the end of the 1920s. The collective sense of professional identity among nascent ‘chemical engineers’ developed rapidly during this time owing to associations which promoted their cause among potential patrons. -/- .

The development of a professional identity is particularly interesting for those occupations that have a troubled emergence. The hinterland between science and technology accommodates many such ‘in-between’ subjects, which appear to have distinct attributes. Some of these specialisms disappear in the face of culturally stronger occupations. Others endure, their technical expertise becoming appropriated or mutated to serve the needs of different professional groups. This chapter is concerned with one extreme of these interstitial specialisms. Chemical engineering – a subject (...) that by its very name is between the science of chemistry and the technology of engineering – did eventually become a profession, in at least some countries. It had a relatively easy time becoming established in America in the first third of this century, but chemical engineering remained largely unrecognised in Germany until the 1960s, and has attracted a smaller professional community there. In Britain, the chemical engineering profession has evinced distinct transitions over a period of a century. It emerged to become an influential contributor to western economies and one of the ‘big four’ engineering professions (along with civil, mechanical and electrical engineering) after the second world war, due in large part to the unmindful aid of an influential, if capricious, sponsor: the state. Yet chemical engineers had a long and troubled history of contestation with other professions. Because of this, the British case is particularly appropriate for examining the continual re-casting of the professional identity in response to external and internal pressures. (shrink)

This paper examines the membership of the professionalassociation of chemical engineering in Britain – the Institutionof Chemical Engineers – during its first three decades. Usingcollective methods of biography, it explores how long it took forclear boundaries to develop between this membership and the widerchemical community. Delineation was linked to the development ofan academic discipline. This paper argues that the indeterminateconstituency of the IChemE delayed growth, but allowed it to playa key role in shaping the development of the (...) new profession. (shrink)

Summary James Watt (1736–1819) is best known as an engineer who dramatically improved the efficiency of the steam engine. What we take to be his chemical interests are conventionally seen as peripheral to his main line of work. He is usually treated as a chemist in three main contexts: his ‘practical’ chemical work relating to chlorine bleaching, varnishes, pottery, and so on; his work with Thomas Beddoes on the medicinal uses of various ‘airs’; his, much disputed, claim as (...) a chemical discoverer in the case of the composition of water. In this paper, I argue that Watt himself, and his contemporaries, saw the centrepiece of his steam engine work—the separate condenser—as a chemical invention. I also suggest more broadly that Watt understood the steam engine as a chemical device. For Watt and his Scottish friends, the study of steam and heat was a chemical enquiry. The subsequent changes in the place of heat in chemical enquiry in the early nineteenth century led to a reclassification of Watt's chemical investigations as ‘physics’. This, in turn, produced the sharp separation of his chemical and engineering activities characteristic of modern historiography. Watt's steam engine, which is usually placed in the lineage of machines understood as heat engines, and explained by the laws of thermodynamics, is better seen in context as a chemical device. Watt's ‘indicator diagram’ is reassessed in the light of this. (shrink)

The aim of this study was to investigate the use of a newly developed design game called BLOCKS to stimulate awareness of ethical responsibilities amongst engineering students. The design game was played by seventeen teams of chemical engineering students, with each team having to arrange pieces of colored paper to produce two letters each. Before the end of the game, additional constraints were introduced to the teams such that they faced similar ambiguity in the technical facts that (...) the engineers involved in the Challenger disaster had faced prior to the space shuttle launch. At this stage, the teams had to decide whether to continue with their original design or to develop alternative solutions. After the teams had made their decisions, a video of the Challenger explosion was shown followed by a post-game discussion. The students’ opinion on five Statements on ethics was tracked via a Five-Item Likert survey which was administered three times, before and after the ethical scenario was introduced, and after the video and post-game discussion. The results from this study indicated that the combination of the game and the real-life incident from the video had generally strengthened the students’ opinions of the Statements. (shrink)

The complexity of industrial reality, the plurality of legitimate perspectives on risks and the role of emotions in decision-making raise important ethical issues in risk management that are usually overlooked in engineering. Using a questionnaire answered by 200 engineering students from a major engineering school in Canada, the purpose of this study was to assess how their training has influenced their perceptions toward these issues. While our results challenge the stereotypical portrait of the engineer, they also suggest (...) that the current engineering education might fail to empower engineers to engage in ethical risk management. We therefore propose an active-learning method to help in this matter. Carried out through workshops with 34 students in chemical engineering, the effectiveness of this method has been evaluated using group interviews and questionnaires. Our results suggest that such an approach is effective, at least in the short run, to motivate students to engage in ethical risk management and to trigger reflectivity on what it means to be an engineer today.

Engineering, as a profession and business, is at the sharp end of the ethical practice. Far from being a bolt on extra to the ‘real work’ of the engineer it is at the heart of how he or she relates to the many different stakeholders in the engineering project. Engineering, Business and Professional Ethics highlights the ethical dimension of engineering and shows how values and responsibility relate to everyday practice. Looking at the underlying value systems that (...) inform practical thinking the book offers a framework for ethical decision-making. Covering global corporate responsibility to the increasing concern for the environment within the engineering business, the book offers ways in which value conflict can be handled. Integrating practice, value and diversity the book helps to prepare the engineer for the ethical challenges of the 21st century. This book is essential reading for all students on courses accredited by the Engineering Council e.g. Civil, Chemical, Mechanical and Environmental Engineering who need to be aware of ethics. Also of interest to practicing engineers and professionals such as Sustainability Managers and Community Workers involved in engineering projects. The authors have worked together in the area of engineering, professional and business ethics for many years and are all members of the National Centre for Applied Ethics at the University of Leeds. •Integrates ethical considerations into everyday decision-making •Shows how to review and overcome professional ethical problems •Practical case studies and examples throughout.

On intellectual foundations that distinguished chemical engineering from other disciplines.

The strategic use of disease and poison in warfare has been subject to a longstanding and cross-cultural taboo that condemns the hostile exploitation of poisons and disease as the act of a pariah. In short, biological and chemical weapons are simply not fair game. The normative opprobrium is, however, not fixed, but context dependent and, as a social phenomenon, remains subject to erosion by social (or more specifically, antisocial) actors. The cross cultural understanding that fighting with poisons and disease (...) is reprehensible, that they are taboo, is codified through a web of interconnected measures, principal amongst these are the 1925 Geneva Protocol; the Biological Weapons Convention; and the Chemical Weapons Convention. Whilst these treaties have weathered the storm of international events reasonably well, their continued health is premised on their being ‘tended to’ in the face of contextual changes, particularly facing changes in science and technology, as well as the changed nature and character of conflict. This article looks at the potential for normative erosion of the norm against chemical and biological weapons in the face of these contextual changes and the creeping legitimization of chemical and biological weapons.

The article examines and extends work bringing together engineering ethics and Science and Technology Studies, which had built upon Diane Vaughan’s analysis of the Challenger shuttle accident as a test case. Reconsidering the use of her term “normalization of deviance,” the article argues for a middle path between moralizing against and excusing away engineering practices contributing to engineering disaster. To explore an illustrative pedagogical case and to suggest avenues for constructive research developing this middle path, it examines (...) the emergence of green chemistry and green engineering. Green chemistry began when Paul Anastas and John Warner developed a set of new rules for chemical synthesis that sought to learn from missed opportunities to avoid environmental damage in the twentieth century, an approach that was soon extended to engineering as well. Examination of tacit assumptions about historical counterfactuals in recent, interdisciplinary discussions of green chemistry illuminate competing views about the field’s prospects. An integrated perspective is sought, addressing how both technical practice within chemistry and engineering and the influence of a wider “social movement” can play a role in remedying environmental problems.

Recent research on human problem solving has largely focused on laboratory tasks that do not demand from the subject much prior, task‐related information. This study seeks to extend the theory of human problem solving to semantically richer domains that are characteristic of professional problem solving. We discuss the behavior of a single subject solving problems in chemical engineering thermodynamics. We use as a protocol‐encoding device a computer program called SAPA which also doubles as a theory of the subject's (...) problem‐solving behavior. The subject made extensive use of means‐ends analysis, similar to that observed in semantically less rich domains, supplemented by recognition mechanisms for accessing information in semantic memory.

Eighty percent of (commercial) genetically engineered seeds (GES) are designed only to resist herbicides. Letting farmers use more chemicals, they cut labor costs. But developing nations say GES cause food shortages, unemployment, resistant weeds, and extinction of native cultivars when “volunteers” drift nearby. While GES patents are reasonable, this paper argues many patent policies are not. The paper surveys GE technology, outlines John Locke’s classic account of property rights, and argues that current patent policies must be revised to take account (...) of Lockean ethical constraints. After answering a key objection, it provides concrete suggestions for implementing its ethical conclusions. (shrink)

This is a comment on Tihamér Margitay’s “From Epistemology to Ontology,” where he criticizes Polanyi’s claim that there is a systematic correspondence between the levels of ontology and the levels of tacit knowing. Margitay contends that Polanyi supports this correspondence by appealing to a “purely ontological argument,” one which concludes that it is impossible to reduce machines to a singular, chemical-physical type, and criticizes this claim by pointing to industrial standards (machines that do reduce to singular physical-chemical type). (...) I respond to Margitay’s claim by distinguishing two different “purely ontological arguments” in Polanyi’s thought (one relying on the multi-realizability of a machine in different physical-chemical types, the other pointing to the inability of a purely physical-chemical ontology to account for the artificial shaping and functioning of machines). With these two arguments clarified, Margitay’s criticism by appealing to industrial standards loses much of its initial force. (shrink)

Artificial intelligence can be a game changer to address the global challenge of humanity-threatening climate change by fostering sustainable development. Since chemical research and development lay the foundation for innovative products and solutions, this study presents a novel chemical research and development process backed with artificial intelligence and guiding ethical principles to account for both process- and outcome-related sustainability. Particularly in ethically salient contexts, ethical principles have to accompany research and development powered by artificial intelligence to promote social (...) and environmental good and sustainability while preventing any harm for all stakeholders affected.

ABSTRACT During a visit to Europe in the autumn of 1882, Henry Augustus Rowland, Professor of Physics at Johns Hopkins University, displayed diffraction gratings produced on a ruling engine he had designed and built, which were bigger and much higher quality than any previously made. Some were of a novel type, ruled on concave surfaces, which he used in a simple but equally novel spectroscope that he had devised, to reveal spectral lines in great detail, and by means of photography (...) to record spectral data much more rapidly than previously possible. Over about twenty years Rowland built three ruling engines, published photographic maps of the solar spectrum, compiled a catalogue of the wavelengths of lines in the solar spectrum correlated with laboratory-produced spectra of almost all the chemical elements, and produced and sold the diffraction gratings used by spectroscopists everywhere. For decades after his death Rowland’s ruling engines remained practically the only source of good-quality diffraction gratings. This paper describes and analyses this work of Rowland and of the other men, Theodore Schneider, John Brashear, and Lewis Jewell, who played major roles in it. (shrink)

Despite the application of 2.5 million tons ofpesticides worldwide, more than 40% of all potentialfood production is lost to insect, weed, and plantpathogen pests prior to harvest. After harvest, anadditional 20% of food is lost to another group ofpests. The use of pesticides for pest control resultsin an estimated 26 million human poisonings, with220,000 fatalities, annually worldwide. In the UnitedStates, the environmental and public health costs forthe recommended use of pesticides total approximately$9 billion/yr. Thus, there is a need for alternativenon- (...) class='Hi'>chemical pest controls, and genetic engineering(biotechnology) might help with this need. Diseaseand insect pest resistance to various pests has beenslowly bred into crops for the past 12,000 years;current techniques in biotechnology now offeropportunities to further and more rapidly improve thenon-chemical control of disease and insect pests ofcrops. However, relying on a single factor, like theBacillus thuringiensis toxin that has beeninserted into corn and a few other crops for insectcontrol, leads to various environmental problems,including insect resistance and, in some cases, athreat to beneficial biological control insects andendangered insect species. A major environmental andeconomic cost associated with genetic engineeringapplications in agriculture relates to the use ofherbicide resistant crops (HRC). In general, HRCtechnology results in increased herbicide use but noincrease in crop yields. The heavy use of herbicidesin HRC technology pollutes the environment and canlead to weed control costs for farmers that may be2-fold greater than standard weed control costs. Therefore, pest control with both pesticides andbiotechnology can be improved for effective, safe,economical pest control. (shrink)

First responders to chemical, biological, radiological, or nuclear (CBRN) events face decisions having significant human consequences. Some operational decisions are supported by standard operating procedures, yet these may not suffice for ethical decisions. Responders will be forced to weigh their options, factoring-in contextual peculiarities; they will require guidance on how they can approach novel (indeed unique) ethical problems: they need strategies for “on the spot” ethical decision making. The primary aim of this paper is to examine how first responders (...) should approach on the spot ethical decision-making amid the stress and uncertainty of a CBRN event. Drawing on the long-term professional CBRN experience of one of the authors, this paper sets out a series of practical ethical dilemmas potentially arising in the context of a large-scale chemical incident. We propose a broadly consequentialist approach to on the spot ethical decision-making, but one which incorporates ethical values and rights as “side-constraints”. (shrink)

Dissatisfied with the descriptive and speculative methods of evolutionary biology of his time, the physiologist Jacques Loeb , best known for his “engineering” approach to biology, reflected on the possibilities of artificially creating life in the laboratory. With the objective of experimentally tackling one of the crucial questions of organic evolution, i.e., the origin of life from inanimate matter, he rejected claims made by contemporary scientists of having produced artificial life through osmotic growth processes in inorganic salt solutions. According (...) to Loeb, the answer to the question of whether or not life could be created artificially had to come from macro-molecular chemistry, in particular from the research on the recently discovered DNA. He was convinced that a prerequisite for making living matter from inanimate substances was the chemical synthesis of nuclear material capable of self-replication. Moreover, Loeb, experimentally refuting some vitalistic explanations as well as colloidal chemists’ far-reaching claims that biologically relevant macromolecules follow colloidal rather than chemical laws, pioneered research on the physical and chemical explanations of biological phenomena.

SummaryDiffraction gratings have contributed enormously to modern science. Although some historians have written about them, there is much more to be brought to light. This paper discusses their development and use in the period up to about 1880 before Rowland began to produce them. Rittenhouse described the action of a diffraction grating in 1786, but no explanation was possible until the wave theory of light was developed. Fraunhofer discovered the dark lines in the solar spectrum in 1814, and then investigated (...) diffraction, producing the first ruled gratings, making detailed measurements and calculating the wavelengths of prominent spectral lines. After Bunsen and Kirchhoff showed the association between spectral lines and chemical elements there was an upsurge of interest in measuring wavelengths. The gratings used in this work almost all came from one source, a relatively unknown instrument maker called Nobert, who made them by an extremely laborious process using a machine he had built himself. The most significant wavelength measurements were made by Ångström, but Mascart, Van der Willigen, Stefan, Ditscheiner and Cornu also did important work. Nobert gratings were investigated by Quincke, copied photographically by Rayleigh, and were known and discussed in the USA. Nobert's work helped to advance spectroscopy much more than has been acknowledged. (shrink)

Recently, several critics of the multiple realizability thesis have argued that philosophers have tended to accept the thesis on too weak grounds. On the one hand, the analytic challenge has problematized how philosophers have treated the multiple realization relation itself, claiming that assessment of the sameness of function and the relevant difference of realizers has been uncritical. On the other hand, it is argued that the purported evidence of the thesis is often left empirically unverified. This paper provides a novel (...) strategy to answer these worries by introducing a role for multiple realizability in the context of biological engineering. In the field of synthetic biology, bioengineers redesign the evolutionary realizations of biological functions, even constructing artificial chemical surrogates in the laboratory. I show how in the rational design approach to biological engineering, multiple realizability can function as a design heuristic in which the sameness of function and difference of realizers can be controlled. Although practically motivated, this engineering approach has also a theoretical, exploratory component that can be used to study the empirical limitations of multiple realizability. Successful realization of the engineering designs would amount to a concrete demonstration of multiple realizability, taking evidence for MRT beyond what is readily found in nature. (shrink)

The historical background of the discovery of adverse health effects of medicines, food additives, pesticides, and other chemicals is reviewed, and the development of national and international regulations and testing procedures to protect the public against the toxic effects of these drugs and chemicals is outlined. Ethical considerations of the safety evaluation of drugs and chemicals by human experimentation and animal toxicity studies, ethical problems associated with clinical trials, with the falsification of clinical and toxicological data, and with inadequate experimental (...) methodology, are reviewed, and the ethics of the marketing of drugs and their post-marketing surveillance, are similarly considered. These ethical problems are illustrated with many specific examples, including the drugs neoarsphenamine, chloramphenicol, thalidomide, diethyl stilboestrol and benoxaprofen. (shrink)

This paper undertakes a content analysis of newspaper articles from Australia, the UK, and the US concerned with a variety of issues relevant to sustainable food and agriculture from 1996 to 2002. It then goes on to identify the various ways in which sustainability, organic food and agriculture, genetic engineering, genetically modified foods, and food safety are framed both in their own terms and in relation to each other. It finds that despite the many competing approaches to sustainability found (...) in scientific and agricultural production discourses, media discourses tend to reduce this complexity to a straightforward conflict between organic and conventional foods. Despite regular reporting of viewpoints highly critical of organic food and agriculture, this binary opposition produces discourses in which organic foods are seen as more-or-less synonymous with safety, naturalness and nutrition, and their alternatives as artificial, threatening, and untrustworthy. Particularly controversial food-related issues such as genetic engineering, food scares, chemical residues, and regulatory failure are treated as part of the same problem to which organic food offers a trustworthy and easily understood solution.

In 2002 the American Chemical Society (ACS) asked its members to submit proposals for the "ten most beautiful experiments in chemistry" (C&EN, Nov. 18, 2002, p. 5) and then proudly published the result of the vote in its Chemical and Engineering News magazine (C&EN, Aug. 25, 2003, pp. 27-30). Democratic as the procedure is, it avoids asking critical questions: What is an experiment? What is beauty? What is chemistry? In fact, you need not be able to give (...) an answer to these questions in order to vote. We could even imagine none of the voters being able to answer any of the questions in explicit terms. And yet, the members of the society might correctly consider the result valid, not only with regard to the top ten list but also regarding its implicit definitions of what ‘experiment’, ‘beauty’, and ‘chemistry’ means. The result thus reflects the tacit knowledge and the unquestioned feelings of the majority, as they have previously been trained to respond to such unusual questions, and helps newcomers to acculturate easily. However, such implicit consensus definitions and assessments are neither binding for non-members, nor suitable for explicit debates. Prompted by the questions of what a beautiful experiment in chemistry is, you might repeat the top ten list you have learnt by heart, but otherwise remain silent. (shrink)

Transgenic crops currently available foruse potentially provide environmental benefits, suchas reduction in insecticide use and substitution ofless toxic for more toxic herbicides.

Are there circumstances under which scientists and engineers doing their ordinary jobs can be thought of as participants in a social movement? The technoscientists analyzed in this article are at the forefront of a new way of doing chemistry; they are attempting to redesign chemical products and synthesis pathways to significantly reduce health effects and environmental damage from industrial chemicals. Green chemistry practitioners and entrepreneurs now constitute a small minority of chemists and chemical engineers in the university, government, (...) and corporate sectors, but the innovators gradually are institutionalizing their efforts and winning converts. Drawing on concepts from social movement theory, the authors argue that examining green chemistry as a social movement sheds light on the intentional social organization of emerging scientific and engineering disciplines, advances thinking about the role of expertise in social change, and uncovers a possible pathway toward reconstructing chemical technologies on a more environmentally sustainable basis. The article closes with questions about potential coalitions among green chemists and engineers, regulators, and activist sectors of civil society. (shrink)

A guide to the everyday decisions about right and wrong faced by physical scientists and research engineers. This book offers the first comprehensive guide to ethics for physical scientists and engineers who conduct research. Written by a distinguished professor of chemistry and chemical engineering, the book focuses on the everyday decisions about right and wrong faced by scientists as they do research, interact with other people, and work within society. The goal is to nurture readers' ethical intelligence so (...) that they know an ethical issue when they see one, and to give them a way to think about ethical problems. After introductions to the philosophy of ethics and the philosophy of science, the book discusses research integrity, with a unique emphasis on how scientists make mistakes and how they can avoid them. It goes on to cover personal interactions among scientists, including authorship, collaborators, predecessors, reviewers, grantees, mentors, and whistle-blowers. It considers underrepresented groups in science as an ethical issue that matters not only to those groups but also to the development of science, and it examines human participants and animal subjects. Finally, the book examines scientifically relevant social issues, including public policy, weapons research, conflicts of interest, and intellectual property. Each chapter ends with discussion questions and case studies to encourage debate and further exploration of topics. The book can be used in classes and seminars in research ethics and will be an essential reference for scientists in academia, government, and industry. (shrink)

By an inventor and chemical engineer, this slim volume is designed primarily for the adolescent and could conceivably do some good in some cases. Theistically oriented.—P. S.

Although theoretical results for several algorithms in many application domains were presented during the last decades, not all algorithms can be analyzed fully theoretically. Experimentation is necessary. The analysis of algorithms should follow the same principles and standards of other empirical sciences. This article focuses on stochastic search algorithms, such as evolutionary algorithms or particle swarm optimization. Stochastic search algorithms tackle hard real-world optimization problems, e.g., problems from chemical engineering, airfoil optimization, or bioinformatics, where classical methods from mathematical (...) optimization fail. Nowadays statistical tools that are able to cope with problems like small sample sizes, non-normal distributions, noisy results, etc. are developed for the analysis of algorithms. Although there are adequate tools to discuss the statistical significance of experimental data, statistical significance is not scientifically meaningful per se. It is necessary to bridge the gap between the statistical significance of an experimental result and its scientific meaning. We will propose some ideas on how to accomplish this task based on Mayo's learning model. (shrink)
