An integrated power process model for ethylene production

Abstract

This study develops an economic model of a newly designed ethylene plant to evaluate the effects of increasingly restrictive waste water treatment requirements on the costs of producing ethylene, feedstock choice, and the marginal costs of treating major pollutants. Zero discharge of pollutants to the water is attained in the model plant at a production cost increase of 6.9%. Secondary treatment of organic pollutants increases production costs 0.79% with once‐through cooling and 5.15% with recycle cooling. The controlling organic pollutants at each treatment level are identified, and estimates are made of the potential savings in waste treatment from redesign of the production facilities to ..
