초록 ▼

A liquid degassing apparatus is arranged to limit pervaporation through a membrane by establishing a pervaporation control space at a permeate side of the membrane. The pervaporation control space is defined in a vacuum chamber between the membrane and a shield member. The shield member may be substantially gas and liquid impermeable to maintain an environment in contact with the permeate side of the membrane that is relatively rich in solvent vapor concentration, thereby limiting further liquid pervaporation across the membrane.

1. A liquid degassing apparatus, comprising: a body defining a chamber having a liquid inlet and a liquid outlet, and a vacuum port;a gas-permeable, liquid-impermeable tubular membrane in said chamber and separating said chamber into a permeate side and a retentate side, wherein said retentate side of said chamber is in liquid communication with said liquid inlet and said liquid outlet, and said permeate side of said chamber is in fluid communication with said vacuum port;a tubular shield member disposed in said permeate side of said chamber and interposed between said membrane and said vacuum port, said shield member being substantially gas and liquid impermeable and defining a substantially closed pervaporation control space between said membrane and said shield member, said pervaporation control space assumes a volume of between about 1 and about 30 times the volume of said retentate side of said chamber;a passageway through said shield member to permit limited fluid flow from said pervaporation control space to a chamber space separated from said pervaporation control space by said shield member; anda pump for evacuating said permeate side of said chamber through said vacuum port. 2. A liquid degassing apparatus as in claim 1 wherein a portion of said shield member defining said pervaporation control space is spaced from said membrane by less than about 0.03 inches. 3. A liquid degassing apparatus as in claim 1, wherein said tubular shield member and said tubular membrane substantially concentrically extend between said liquid inlet and said liquid outlet. 4. A liquid degassing apparatus as in claim 3 wherein said membrane is a liquid conveyance tube to convey liquidous material through said chamber from said liquid inlet to said liquid outlet. 5. A liquid degassing apparatus as in claim 1 wherein said passageway permits gas passage from said pervaporation control space to said chamber space only upon at least 1 mm Hg absolute pressure differential between said pervaporation control space and said chamber space. 6. A liquid degassing apparatus as in claim 1, including a flow restrictor in a fluid path between said chamber and said pump, with said flow restrictor and said chamber being suitable for creating a pneumatic pressure oscillation dampener having a time constant that is larger than an oscillation rate of said vacuum pump. 7. A liquid degassing apparatus as in claim 6, wherein said flow restrictor permits up to about 1 mm Hg differential pressure thereacross.
