摘　　要：通过对环丁砜抽提蒸馏工艺影响因素——原料组成、溶剂比、溶剂温度、汽提水含量、塔压的试验分析,以降低生产成本、增加混芳收率为目标,给出了不同原料组成下适宜参数的确定方法。In order to reduce the production cost and increase the yield of mixed aromatic hydrocarbon, influencing factors of the sulfolane extractive distillation process were analyzed, such as raw materials, solvent ratio, temperature, solvent stripping water content and tower pressure. At last, suitable parameters for different raw materials were determined.
