The Cost of Clean Water in Ammonia, Chlor-Alkali,and Ethylene Production,

摘要

National economic plant models were developed for ammonia,chlor-alkali,and ethylene plants to evaluate the economic and technical effects of limiting or not limiting the discharge of any major water,air,or solid waste pollutant. These model plant developments each involved: (1) an identification of the technical substitution possibilities; (2) measurement of the inputs into each process and the outputs,including wastes,from each process; (3) specification of the physical laws and effluent standards restricting the substitution of one production process for another;and (4) organization of the data into a standardized mathematical format for computer evaluation. The national economic plant models developed showed how technical information may be synthesized into a comprehensive economic basis for wastewater policy evaluation.
