The boiling point of propylene glycol methyl ether is about 120 ℃, and it is miscible with water. The recovery configuration is mainly closed collection and graded condensation, and the dehydration of the recovered liquid is mainly distillation. In this paper, the characteristics, collection arrangement, condensation and purification route and operation control points of ether alcohol solvent waste gas are combed.
