Integrated Assessment of Carbon Dioxide Emissions for a Large-Scale Iron and Steel Corporation in China

Abstract

This paper constructs an optimization model about carbon dioxide emissions problem for production process of a large-scale iron and steel corporation in China. Then how to realize maximal profits of corporation is studied under the subjective conditions about production, raw material supply and emissions abatement amount. And the optimized production structure in accordance with production benefits and environment benefits are obtained by non linear programming methodology. Finally the carbon dioxide emissions per unit of steel production are compared with the level of whole China and developed countries, and how to utilize the byproducts of coal gas for multipurpose is also discussed.
