As noted by Wolman ( 3), educational institutions are continually asked to prepare those who will search for solutions of societal problems. Problems in the real world do not separate nicely into "disciplines". We do not see the "botany problem", or the "meteorology problem", or the "chemical engineering problem", as such. Rather, we see a minor by-product from a facility designed by a chemical engineer. Released, it is transported by meteorological processes, and becomes of concern because a botanist foresees ecological damage as a consequence of its downwind presence. Thus while disciplines and departments in universities are an administrative convenience and provide a perhaps needed foundation for specialized research and education, educational institutions also must address problems which do not fit nicely into present disciplinary units. 

Self-Test 4.6B A 10.0-mol sample of gas in an industrial reactor of fixed volume must be kept at a constant pressure of 5.00 atm. As the tank is heated, the temperature rises from an initial 25°C to a final 300°C. To maintain the pressure, the engineer releases some of the gas through a safety t valve. How much gas (in moles of molecules) must be released to maintain the constant pressure ... 

In 1992, the Center for Chemical Process Safety (CCPS), a section of the American Institute of Chemical Engineers, released a how-to book [28] which contains practical appendices on inspection and test procedures. These appendices comprise the practices at major chemical manufacturing facilities. Chapter 8 should be consulted for specific information and actual plant programs. 

At one time, very large amounts of lead were used in the production of tetraethyl lead, a compound that reduces the amount of knocking in an internal combnstion engine. The problem with tetraethyl lead, however, is that it tends to break down within an engine, releasing free lead to the environment. Because of the health hazards that lead poses for humans and other animals, tetraethyl lead has been banned for use as a gasoline additive.
