摘　　要：通过分析MDEA脱硫溶液吸收选择性的影响因素,确定了气液比和塔板数为工艺调整的主要手段。通过增大装置气液比,降低胺液循环量和吸收塔塔板数,可提高胺液对H2S的选择性吸收性能,增加产品气收率,减少装置的电力、蒸汽及胺液消耗。By analyzing the influence factors of selective absorption about MDEA desulfurization, it was identified that adjusting gas-liquid volume ratio and absorber plate numbers were the main optimi- zation methods of the process. By increasing the gas-liquid volume ratio, reducing amine circulation flow and the numbers of absorber plate, the selective absorption performance of amine could be im- proved. As the results, the product gas yield could be increased, and the consumption of electricity, steam and amine could be reduced.
