Beyond science and technology, chemical engineering students today must study economics, other business courses, and subjects in the humanities to understand sociopolitical, environmental, health, and safety issues. Couper (U. of Arkansas, Fayetteville) traces the steps of a chemical engineer's typical career path, from financing a business plan to achieving an optimum balance of all costs relevant to an operation/problem solutions. He explains process economics as the method toward this end. Includes a glossary, engineering rules of thumb and other technical appendices.
