摘　　要：为使脱硫后的炼厂干气中H2S含量达标(一般不大于20ppm),分析了操作温度、操作压力、气液摩尔比以及助剂的添加对MDEA法脱硫效果的影响。干气脱硫塔的操作温度宜控制在38℃~42℃,操作压力宜控制在0.6MPa~1.5MPa,气液摩尔比宜控制在0.55~0.57,此外,向MDEA中加入物理溶剂、离子液体,常见有机胺或空间位阻胺能够提高MDEA对H2S的脱除效果。In order to make the H_(2)S content in the desulfurized refinery dry gas meet the standard(generally no more than 20ppm),the effects of operating temperature,operating pressure,gas-liquid molar ratio and the addition of additives on the desulfurization effect of MDEA method were analyzed.The operating temperature of dry gas desulfurization tower should be controlled at 38℃~42℃,the operating pressure should be controlled at 0.6MPa~1.5MPa,and the gas-liquid molar ratio should be controlled at 0.55~0.57.In addition,adding physical solvent,ionic liquid,common organic amine or steric amine to MDEA can improve the removal effect of H_(2)S by MDEA.
