The reactive dividing wall column (RDWC) is a column structure that couples a reactive distillation and dividing wall column. It has become a research hotspot because of its remarkable advantages in energy consumption. Most RDWCs ignore the possibility of cross-wall heat transfer. For the RDWC, the effect of reaction heat is also ignored. In this work, the reaction of methyl acetate with butanol was studied, and Aspen is used to study the effect of the reaction heat and reaction region length on the cross-wall heat transfer. The results show that compared with the RDWC with an adiabatic cross-wall, the RDWC with cross-wall heat transfer can save 3.2% energy. Cross-wall heat transfer could achieve reactants conversion of 99.4%. From the perspective of energy saving maximization, the double reaction region is set. The research results show that the RDWC with cross-wall heat transfer in the double reaction region can save 4.2% energy compared with the cross-wall insulation.

基于跨壁传热的反应分隔壁塔反应区设计

反应性分隔壁塔（RDWC）是一种将反应性蒸馏和分隔壁塔耦合的塔结构。因其在能耗方面的显着优势而成为研究热点。大多数 RDWC 忽略了跨壁传热的可能性。对于RDWC，反应热的影响也被忽略了。本工作研究了乙酸甲酯与丁醇的反应，利用Aspen研究了反应热和反应区长度对跨壁传热的影响。结果表明，与带绝热跨壁的RDWC相比，带跨壁传热的RDWC可节能3.2%。跨壁传热可实现 99.4% 的反应物转化率。从节能最大化的角度出发，设置双反应区。
