Advanced treatment method for co-produced ethers in malonic ester production tail gas

The invention relates to the technical field of treatment of chemical production tail gas, in particular to the technical field of treatment of malonic ester production tail gas and discloses an advanced treatment method for co-produced ethers in the malonic ester production tail gas. The method comprises steps as follows: hydrogen chloride in the malonic ester production tail gas is absorbed by an absorbent, the malonic ester production tail gas without hydrogen chloride is cooled and condensed, liquid esters are obtained, and uncondensed residual tail gas is incinerated. With the adoption of the method, main components contained in the malonic ester production tail gas can be recovered respectively, resource treatment is realized, recovered products can realize certain economic benefits, and environmental pollution caused by improper tail gas treatment is avoided. 本发明涉及化工生产尾气处理技术领域，尤其是涉及丙二酸酯生产尾气的处理技术领域，公开了种丙二酸酯生产尾气的深度处理联产醚类的方法，包括用吸收剂吸收丙二酸酯生产尾气中的氯化氢，将去除了氯化氢的丙二酸酯生产尾气降温，冷凝得到液体醚，将未冷凝的剩余尾气焚烧。本发明方法能够将丙二酸酯生产尾气中含有的
