采用氯磺酸磺化法合成了一种含有磺酸基和羧基的新型络合剂磺化戊二酸(SG),用 SG与乙二胺四乙酸、柠檬酸、FeCl3配制出一种三元络合铁脱硫体系。在连续脱硫装置中考察脱硫液与硫化氢气体体积比、装置运行时间、填料高度等脱硫工艺条件对复配脱硫体系脱硫效率的影响,在再生装置中考察空气流量、再生时间、再生温度等再生工艺条件对复配脱硫体系再生率的影响。结果表明:在脱硫液与含硫化氢原料气体积比为0.134、填料高度为0.4 m、脱硫温度为40℃、初始 pH为8.0的条件下,原料气中的 H2 S质量浓度可由227.679 g?m3降到0.011 g?m3,脱除率达99.99%;在空气流量为125 L?h、再生时间为30 min、温度为30℃、初始 pH为8.0的条件下,脱硫剂的再生率达93.24%。
