| 摘 要： | 为了避免醇解工段放空尾气中有机物含量超标对大气环境造成的污染,利用闲置设备,用水将尾气中甲醇、醋酸甲酯、乙醛吸收后,再放空。吸收液送回收工段处理回收甲醇、醋酸甲酯、乙醛。改造不仅降低甲醇消耗、提高醋酸回收率,而且确保放空尾气达到国家大气二级排放标准。

| Abstract: | To avoid organic superscalar in off - gas from alcoholysis work section polluting air environment, the offgas should be emptied after absorbing methanol, methyl acetate, acetaldehyde, using idle equipment. Thenabsorption liquid was returned to recovery section to recover methanol, methyl acetate and acetaldehyde. The improvement not only lowered methanol＇sconsumption, raised acetic acid＇s recovery, and also ensured emptied offgas reaching the class B State discharge standard. |

| Keywords: | absorption recovery processing discharge reaching the standard |
