Comparison of steel manufacturing off-gas utilization methods via life cycle analysis

Abstract

This study utilizes life cycle analysis to compare three steel manufacturing off-gas utilization systems: a status quo system, which produces electricity via a low-pressure steam turbine; a combined cycle power plant system, which produces electricity using gas and steam turbines; and a methanol production system, which converts coke oven gas and blast furnace gas into methanol. This research seeks to compare the environmental impacts of each …
