Abstract:

Using thiophene/isooctane to model gasoline，the effects of extractant and solvent/oil ratio on vapor-liquid equilibrium were researched on a self-made small vapor-liquid equilibrium apparatus and the relative volatility of thiophene/isooctane system was determined. Two chemical process flow simulation softwares of PRO/II and Aspen were used in simulation of the system. Good agreement between the measured results by this work and those of computer simulation was obtained. The relative volatility of thiophene/isooctane is 1.466 by using N,N-dimethylformamide as extractant at solvent/oil ratio of 4∶1.

摘要：

以噻吩/异辛烷模拟汽油为原料，采用自制的小型气液平衡装置，考察了萃取剂、剂油比对体系气液相平衡的影响，确定了噻吩/异辛烷相对挥发度。采用PRO/II和Aspen两大化工工艺流程模拟软件进行模拟计算，发现实验结果与模拟计算结果相吻合。以N,N-二甲基甲酰胺作萃取剂，剂油比为4∶1时模拟体系噻吩/异辛烷相对挥发度为1.466。
