| Abstract: | The operating parameters of double-effect rectification process for methanol were optimized by means of process simulation software Pro II.The results showed that,a suitable operating pressure was 800kPa,the ratio of bottom mass flow and top mass flow in high pressure distillation tower was 1.66.The double-effect rectification process on the optimized parameters was simulated.The thermodynamic analysis for traditional two-tower process and double-effect distillation process showed that the thermodynamic efficiency for double-effect distillation process was 15.95%,which was increased 7.72%compared with the traditional two-tower process. |
