Abstract:
A module for pervaporation or vapor permeation comprising: a central, axial permeate removal tube having a wall with at least one inlet opening therein; at least one separator element mounted on the permeate removal tube adjacent to the inlet opening; the separator element including a permeate transport plate having a transverse opening therethrough for the passage of the permeate removal tube through the permeate transport plate, the permeate transport plate also defining fluid passages disposed radially relative to the permeate removal tube and communicating with said inlet opening therein; a pervaporation membrane enveloping the permeate transport plate; and annular sealing rings located concentrically about the permeate removal tube in engagement with the pervaporation membrane, so that fluid has to pass through the pervaporation membrane to enter the permeate removal tube inlet opening.
