Exergy Analysis of Iron and Steel Eco-Industrial Systems

The iron and steel production industry entails high resource and energy consumption and generates a serious amount of waste and pollution. The need to conserve energy and reduce emissions underlines the importance of correctly and comprehensively evaluating the iron and steel industrial systems. Properly evaluating the utilization levels of resources and energy is one of the important tasks. In this publication I introduce a thermodynamic exergy analysis method to analyze and evaluate iron and steel industrial systems. The utilization levels of resources and energy are evaluated by comparing the result of the exergy calculation for the traditional production chain and for the material and energy recycling eco-industrial chain. The systemic problems are thus revealed and measures for improvement are proposed, providing a theoretical basis for planning and construction of iron and steel eco-industrial parks.
