This difference in vapor pressure can be obtained in different ways: by vacuum applied to the permeate ,the most used laboratory procedure, or by cooling the permeate vapor, causing a partial vacuum, and most common industrially.
The membrane destillation use heat streans to provide the evaporations. The pervaporation uses differente methods.
I hope it help.</span>
