摘　　要：建立了千吨级的渗透汽化苯脱水中试装置 ,并成功地完成了中试试验研究 .结果表明该装置可将苯中的水含量从质量分数为 0 0 6%脱至 0 0 0 3%以下 ,对膜后真空度的要求不很苛刻 (～ 2 0 0 0Pa) .初步的经济分析表明 ,渗透汽化脱除苯中的微量水比恒沸精馏法节能 2 / 3.试验结果为万吨级渗透汽化苯脱水装置的设计提供了基础数据 .The pilot equipment of pervaporation which was used to dehydrate from benzene solution of thousand ton per year was set up. The pilot experiment was conducted successfully. The results show that this process can take off the water from benzene solution from 0.06% to lower than 0.003%. The pressure in the vaccum side of the membrane module was about 2?000?Pa. The operation cost for dehydration of 50 thousand ton benzene per year using pervaporation and which using constant-boiling-rectification were compared. The results show that 60% energy can be saved using pervaporation compared with using constant-boiling-rectification. The pilot results provided basic data for designing the equipment of dehydration of ten thousand ton benzene per year with pervaporation.
