【摘要】 随着我国新材料产业发展规划及禁塑令的提出，可生物降解的1,4-丁二醇生产迎来发展机遇。本文采用Aspen Plus V11化工流程模拟软件对改良Reppe法生产1,4-丁二醇工艺进行全流程模拟，以再沸器热负荷最低为优化目标，利用Sensitivity模块对各精馏塔进行优化，并采用新型分离技术以节约能耗。模拟与优化结果表明：生产的1,4-丁二醇可满足工业优等品要求，同时联产工业优等品正丁醇，正丁醇分离塔采用热泵精馏替代普通精馏后，综合能耗下降了68.79%。相关模拟结果可为改良Reppe法制1,4-丁二醇工业化生产提供理论依据和科学指导。更多还原

【Abstract】 With the development of the new material industry planing and the propose of the plastic forbidden order, the production of biodegradable 1,4-butanediol is confronting with significant development opportunity.In this paper, Aspen Plus V11 chemical process simulation software is adopted to simulate the whole process of 1,4-butanediol production by modified Reppe method, the sensitivity module is used to optimize the distillation tower with the minimum heat load of the reboiler as the optimization object, and new energy saving separation technology is performed to reduce the energy consumption according to the characteristics of the separation system.The simulation and optimization results showed that the industrial superior product 1,4-butanediol and co-product n-butanol can be obtained.Furthermore, the comprehensive energy consumption of n-butanol separation tower can be reduced 68.79% by using heat pump distillation instead of conventional distillation.The relevant results can provide a theoretical basis and scientific guidance for the industrial production of 1,4-butanediol by Reppe method.更多还原
