查询词典 column

The presumption that new technology about distillation column with a single reactor can be used in photochlorination of acetic acid is first proposed in this paper. The fact that reaction distillation has obvious advantages in the number of theoretically perfect trays and energy consumption was obtained by theoretical analysis between the coupling of reaction and distillation and the independent operation, which lays a theoretical foundation on the application of the distillation column with a single reactor in photochlorination of acetic acid.

本文首次提出了将背包式反应精馏耦合技术应用于乙酸氯化反应的设想，通过对反应精馏耦合和反应精馏独立操作两种情况进行理论分析，发现反应精馏耦合在理论板数、能耗方面均具有明显优势，因而为背包式反应精馏应用于乙酸光氯化反应奠定了理论基础。
