Abstract
A flow-through vacuum degassing unit for degassing a liquid includes a vacuum chamber adapted to be connected to a source for creating a vacuum in the chamber, inlet and outlet connections for admitting and discharging liquid to be degassed and one or more tubes for conducting the liquid through the chamber, wherein the tube is formed in a predetermined, memoried configuration and capable of self-supported containment in the vacuum chamber, the tube being of a thin-walled semi-permeable polymeric resin material.
Claims18
A flow-through vacuum degassing unit for degassing one or more liquids comprising:
- (a) a vacuum chamber adapted to be connected to a source for creating a vacuum in the chamber;
- (b) inlet and outlet connections for admitting and discharging liquid to be degassed;
- (c) one or more continuous tubes for conducting the liquid through the chamber, each such tube being connected between one of said inlet and one of said outlet connections and each such tube being formed in a predetermined, memoried configuration having an outer surface and being capable of self-supported containment in an unreinforced state in the vacuum chamber, such that the outer surface of such continuous tube is essentially totally exposed to the vacuum, each such tube being a thin-walled polymeric resin material permeable to pass dissolved atmospheric gases therethrough but liquid impermeable.
