Method for the Recovery of Solvents that have been Adsorbed onto an agent adsorption from air exhaust fumes of solvent.

摘要

Process and Installation for the Recovery of Solvents that have been absorbed into an agent of Absorption from Exhaust Air containing Solvent Vapors.Driving a current Hot Inert Gas as medium through the absorption Desorption Agent, Isolating by Cooling, condensation, solvent Vapors collected by the flow of Inert Gas, separating the Condensed Solvent and returning to use as a means of The Flow of Inert Gas Desorption again heated and Poor Solvent Vapors.Compress the stream of Inert Gas filled with Solvent Vapour for condensation of solvent Vapors isolate, possibly after a pre Cooling, and Cools the current in an expansion turbine along with provision of work.
