Methyl acetate has a boiling point of about 58 ℃, fast volatilization at normal temperature and is flammable. The recovery is mainly based on closed collection and more than two stages of deep condensation. Tail gas with low concentration and large air volume should be adsorbed and concentrated before condensation. In this paper, the characteristics of methyl acetate waste gas, collection arrangement, condensation configuration and recovery liquid reuse points are combed.
2026-10-09The 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.
