Economic evaluation is necessary in deciding whether to pursue proposed business ventures. No business is too small to ignore economic evaluation, none too large to override it. This book describes how economic evaluations are performed in the chemical processing industries and illustrates them by appropriate examples. It stresses methods actually employed in real situations and suggests how results can be interpreted. To the extent possible the authors use common business language rather than specialized terms in order that new concepts will be more readily understood by those encountering the subject for the first time. The book will be of value to those who are called upon to evaluate the economics of chemical processing ventures, and also to students seeking to understand how such evaluations are made.
