【Abstract】 The paper introduces the application of highly efficient flowguided sieve tray and BHSⅡ type packing in the revamping of a methanol distillation column, presents its structural features, and studies its operation performance. Advanced simulation software was used to optimize the revamping project, and put the optimized project into practice. The result showed that the combined application of highly efficient flowguided sieve tray and BHSⅡ type packing was far better than the original bubble tray. After revamping, the process capacity was increased to nearly twice the original capacity. The efficiency was evidently improved, and the energy consumption was greatly decreased.更多还原
