JunKyu Park et al.

Summary: The study models an H2S removal unit for steel-manufacturing coke-oven gas and suggests optimal operating conditions and safety analysis for absorption and regeneration columns. Sensitivity analysis was performed to determine the minimum MDEA solution flow rate, and optimize the L/G ratio and regeneration column pressure. In optimal conditions, reductions of 35% and 23% were expected for MDEA solution and heating duty, respectively.
