Criteria to Evaluate Cokemaking Strategy for an Integrated Steel Plant

Abstract

Previous studies have compared byproduct and heat recovery coke oven technology from a variety of standpoints, including capital and operating cost, steel plant configuration, and plant energy balance.1–5 Methodologies have been developed to evaluate important variations such as coal blend changes on, for example, energy consumption and environmental performance.6–8 Material and energy balances for byproduct and heat recovery coke oven operations are developed and analyzed from an energy balance perspective. The results provide important criteria for design engineers to determine the appropriate cokemaking strategy for an integrated steel plant and for process engineers to optimize the coke plant operation.
