Abstract
Liquid, especially water, flowing at a first velocity and at a first pressure in a line having a first cross-sectional area, is deaerated by flowing said stream into and through a region in said line having a second cross-sectional area less than said first cross-sectional area, whereupon in said region the velocity of said stream increases, the pressure of said stream decreases, and gas dissolved in said stream evolves from said stream, and recovering said evolved gas separately from said liquid before it redissolves into said liquid.
Claims7
A method for deaerating liquid, especially water, that contains air, oxygen, nitrogen, or other gas dissolved therein, by
- (a) providing a stream of said liquid flowing at a first velocity and at a first pressure in a line having a first cross-sectional area,
- (b) flowing said stream into and through a pressure reduction region in said line having a second cross-sectional area less than said first cross-sectional area, whereupon in said region the velocity of said stream increases, the pressure of said stream decreases, and gas dissolved in said stream evolves from said stream, and
- (c) recovering said evolved gas separately from said liquid before it redissolves into said liquid.
Apparatus useful for deaerating a liquid having gas dissolved therein, comprising
- a conduit for carrying a stream of said liquid, the conduit having a first cross-sectional area and having a region having a second cross-sectional area less than said first cross-sectional area, and
- a separatory vessel having an inlet in fluid communication with the outlet of said region.
