DEGASSER AND METHOD OF STRIPPING GAS FROM A LIQUID

摘要

A degasser (10) includes a vessel (12) having a series of chambers (18,20,22,24). Liquid containing a gas is directed through the vessel (12) and the chambers (18,20,22,24) therein. A stripping gas is injected into the vessel (12) and moves through the vessel in a counter-current direction relative to the flow of liquid. More particularly, the stripping gas moves from one chamber to another chamber in an upstream direction (relative to the flow of the liquid) and is mixed with the liquid in each chamber (18,20,22,24), causing gas in the liquid to be displaced. Displaced gas is vented from the vessel (12) at a location near where the liquid enters the vessel (12).
