项目简介:在化工生产过程中会有大量的低浓度的醋酸水溶液产生,由于醋酸与水相对挥发度较小,因此要从低浓度的醋酸水溶液中回收醋酸必须采用较高的精馏塔设备,而且能耗很大。本技术可以实现对低浓度 Project Description: There will be a large number of low-concentration acetic acid aqueous solution in the chemical production process. Because of the relatively low volatility of acetic acid and water, it is necessary to use higher rectification column equipment to recover acetic acid from low-concentration acetic acid aqueous solution, And energy consumption is great. This technique can achieve low concentrations
