Appts. for recovery of solvents from output air - involves membrane pervaporation as dividing layer, with air absorbed in viscous organic fluid

摘要

The output air is absorbed in a viscous organic fluid, i.e. glycoether, subjected to a membrane pervaporation. On the dividing layer of the membrane pervaporatin is connected a rectification in an amplifer column and/or a one or multiple stage condensation at differing pressures. USE - To recover solvents from output air.
