结合差压热耦合和反应精馏工艺优势,提出形成差压热耦合反应的精馏工艺方法,将其应用于乙酸甲酯水解过程。在验证UNIQ-HOC模型对模拟该体系适用性的基础上,对影响该工艺的主要影响因素进行考察,得出优化后的主要操作参数,并对比差压热耦合精馏和常规流程的能耗。结果表明,差压热耦合反应精馏增加813.33 kW的功耗,减少7062.3 kW的热量,节能效果显著。

A different pressure thermally coupled reactive distillation column was proposed for the methyl acetate hydrolysisprocess by combining differential thermal coupled distillation with reactive distillation. It was verified that UNIQ-HOC modelcan be successfully applied to VLE prediction of this system. The main parameters affecting the process were investigated andthe optimized operating parameters were obtained. The results show that the different pressure thermally coupled reactive dis-tillation process can save about 89% of energy compared with the conventional process.
