对比纤维液膜接触器与筛板塔的传质面积、N-甲基二乙醇胺（MDEA）与4种复配型溶剂（UDS-Ⅰ， UDS-Ⅱ，UDS-Ⅲ，UDS-Ⅳ）对有机硫的溶解性能，并在纤维液膜接触器内考察操作条件对优选溶剂脱硫效果的影响。结果表明：在纤维液膜接触器内以 UDS-Ⅳ为优选溶剂脱除液化气中的硫化物，可从提高传质面积、传质推动力等方面提高有机硫传质速率，从而提高有机硫脱除率；UDS-Ⅳ溶剂对总有机硫的脱除率较 MDEA 高45．7百分点，总有机硫在 UDS-Ⅳ溶剂-液化气体系的分配比较 MDEA-液化气体系增加6～9倍；在优化的工艺条件下，UDS-Ⅳ溶剂可将焦化液化气的 H2 S 和总硫分别脱除至1 mg/m3和240 mg/m3以下，总有机硫脱除率高达93％以上。

The mass transfer areas of the fiber film contactor and the sieve plate tower,and the sol-ubility for organosulfurs of N-methyldiethanolamine (MDEA )and formulated solvents (UDS-Ⅰ, UDS-Ⅱ,UDS-Ⅲ,UDS-Ⅳ)were compared. In addition,the influence of operation conditions on the desulfurization performance of the preferred formulated solvent UDS-Ⅳ was investigated. The results indicate that the process combining UDS-Ⅳ and a fiber film contactor can increase the removal rate for organic sulfurs from LPG with improved mass transfer area and driving force. The removal rate for total organosulfur of UDS-Ⅳ solvent is 45.7 percentage points higher than that of MDEA. Meanwhile,the distribution ratios of organosulfurs in UDS-Ⅳ solvent-LPG system are found 7—10 times as much as those in MDEA-LPG system. Under optimum operation conditions,UDS-Ⅳ solvent can reduce the con-tents of H2 S and total sulfur of the LPG to less than 1 and 240 mg/m3 ,respectively,and the removal ef-ficiency for total organosulfur is above 93%.
