Engineering profession

The American Institute of Chemical Engineers (AIChE) has a 30-year history of involvement with process safety for chemical processing plants. Through its strong ties with process designers, builders, operators, safety professionals and academia, the AIChE has enhanced communication and fostered improvement in the high safety standards of the industry. AIChE publications and symposia have become an information resource for the chemical engineering profession on the causes of accidents and means of prevention. 

Most of the units used in tliis book are consistent with those adopted by the engineering profession in tlie United States. For engineering work, International SySterne (SI) and English units are most often employed in the United States, tlie English engineering units are generally used. Tliese systems of units are shown in Table 4.2.1. ... 

It has been many years since a book was written specifically for the engineer who is involved with so many facets of the engineering profession, and 1 am of the firm opinion that this publication is long overdue. 

Particle Transport. Because many organic chemicals bind with aquatic particulate matter, particle transport can determine the fate of compounds. Sediment transport has been of interest to the engineering profession for many years. Many discussions of the dynamics of fluvial sediment transport have appeared in the literature (11, 12). As with hydrodynamic transport, one strategy for environmental modeling is to "piggy-back the transport of sorbed chemicals on a model of transport of the sediment phase.

The four most cited accidents (Flixborough, England Bhopal, India Seveso, Italy and Pasadena, Texas) are presented here. All these accidents had a significant impact on public perceptions and the chemical engineering profession that added new emphasis and standards in the practice of safety. Chapter 13 presents case histories in considerably more detail. 

Everyone in the engineering profession is familiar with Murphy s Law, "If anything can go wrong, it will ". I also prefer to remember the extended version which states, "If a series of events can go wrong, it will do so in the worst possible sequence". Risk analysis is a sort of Murphy s Law review in which events are analyzed to see the destructive nature that they might produce. 

A second point can be made about the way in which uni" processes came into existence. The emergence of unit process is analogous to that of unit operations, particularly with regard to relevant social groupings involved in this evolution. Industries, professional organizations, particularly AIChE and the American Chemical Society, and universities are involved, as in the case of unit operations. This time, however, the process leading to the identification of unit processes is simpler because the disciplinary identity of the chemical engineering profession is well defined and especially because unit processes, as the name shows, are patterned after unit operations. 

Chemical engineering is a dynamic profession, and its literature continues to evolve. McGraw-Hill and its consulting editors remain committed to a publishing policy that will serve, and indeed lead, the needs of the chemical engineering profession during the years to come. 

Chemical reaction engineering is that engineering activity concerned with the exploitation of chemical reactions on a commercial scale. Its goal is the successful design and operation of chemical reactors, and probably more than any other activity it sets chemical engineering apart as a distinct branch of the engineering profession. 

Even more than the petroleum industry, the petrochemical industry defmes the chemical engineering profession. The evolution of this industry has produced the changes in the country s needs for engineers and continues to evolve and employ most chemical engineers. The raw materials used in chemical synthesis have made the transitions... 

Along with these topics, we attempt a brief historical srrrvey of chemical technology fi om the start of the Industrial Revolution through speculations on what will be important in the twenty-first century. The rise of the major petroleum and chemical companies has created the chemical engineering profession, and their current downsizing creates significant issues for our students future careers. 

The information in this book was obtained from every imaginable source within the environmental science and engineering profession. They include virtually every peer-reviewed journal in the field, every government-issued report, the proceedings of every related conference in the past two decades, as well as publications of commercial companies working in this field. Ultimately the providers of every technology were contacted personally for interviews involving their work. Only top-quality services and products survived the search for information and eventual publication in this handbook. 

K rm n (K3) and Prandtl (P7) indicated analogies between momentum and thermal transport and placed the matter before the engineering profession. Using Karm n s original analysis (Kl) Deissler (D2) indicated that on the basis of the similarity hypothesis the eddy viscosity may be evaluated for steady, uniform flow in the following way ...

Several other improvemonto have been made at different times upon the washing engine, professing to increase its washing power and save fibre but none of them, so far as the Editor is aware, have proved of practical value. 

Although the safe design practices recommended by professional and trade associations have no legal standing where they have not actually been incorporated in a body of law, many of them have the respect and confidence of the engineering profession as a whole and have been accepted by insurance underwriters so they are widely observed. Even when they are only voluntary, standards constitute a digest of experience that represents a minimum requirement of good practice. 

The AIChE was founded in 1908. The AIChE represents over 50,000 chemical engineers in industry, academia, and government. The organization provides leadership in the chemical engineering profession and offers several major meetings a year, publishes several specific journals and more. Visit the AIChE s website for a complete picture of its current activities.

Between the wars, the growing numbers of continuous catalytic processes—in other manufactures as well as petroleum refining and petrochemicals—absorbed more and more chemical engineers. They brought incentives to focus as much on selective reactions of flowing fluids and suspensions as on the separations and particulate solids-processing methods that constituted the unit operations. They also became nuclei of all sorts of opportunities for the chemical engineering profession.
