摘　　要：通过聚酯工艺尾气回收装置的研究,减少乙二醇、乙醛、2-甲基-1,3-二氧戊环等有机物对环境的污染,同时在不影响生产工艺的情况下,合理利用了乙醛精馏塔底的废水,提高了回收乙醛的纯度。Through the research of polyester tail gas recovery device,the environmental pollution caused by ethylene glycol,acetaldehyde,2-methyl-1,3-dioxolane and other organic compounds was reduced.At the same time,the waste water at the bottom of acetaldehyde distillation column was reasonably utilized without affecting the production process,and the purity of recovered acetaldehyde was improved.
