Carbon Recycling for Converting Coke Oven Gas to Methanol for the Reduction of Carbon Dioxide at Steel Mills

All process gases of the steel mill (coke oven gas COG, blast furnace gas BFG, and converter gas BOFG) not used for heating purposes within the steel mills plants are used as power plant fuel for electricity production. If that produced electricity becomes more costly than external electricity than an alternative processing of steel mills’ process gases is necessary. Methanol production via the so called Emission to Liquids (EtL) can be that alternative use. This has already been done in Iceland by using H2 from the water electrolysis plant and CO2 from the residual gas from the geothermal power station to produce renewable methanol. That concept is extended with the utilization of residual H2 from industrial processes in accordance with the last year amended EU Renewable Energy Directive and the Fuel Quality Directive. One source of residual hydrogen is the coke making process.
