Methodology for cokemaking technology selection for operating conditions and expansion of iron and steel works
Selection of cokemaking technology within an Iron Steel Works (I&SW) setting is a complicated problem, involving analysis of coal quality, coke demand and supply, environmental regulations, and the plant energy balance. The methodology involves coal blend selection, preparation, charging, cokemaking and quenching technology selection to meet the blast furnaces' coke quality requirements and the I&SW energy balance. Hatch's mass and energy balance, OPEX, CAPEX, Energy/CO2 and Financial Models provide the client with NPV/IRR ranking and sensitivity analysis to assist in selecting the best strategy amongst by product or heat recovery ovens, charging and quenching systems for replacement or expansion programs.
