Abstract
The auxiliary or working liquid is cleaned by being urged through a pervaporation membrane module (3), then the permeate stream from the membrane module is led through a condenser (4), where the impurities concentrated in the permeate stream precipitate. The stream of retentate and the stream of permeate from the membrane module are then fed back to a compressor (1). The differential pressure of the compressor belonging to the compressor system is used to operate this circuit.
