Abstract:

Using thiophene/isooctane to model gasolinethe 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 41.

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/IIAspen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41时模拟体系噻吩/异辛烷相对挥发度为1.466
