Abstract
A degasser having a flapper opening including a hinge. The hinge may permit purging of any liquids and solids without regular human intervention. There may be a fixed opening at the base of the degasser, such that there is a constant emptying from the bottom of the tank. The separation of gas from liquid may be involved in applications pertaining to pulping and oxygen delignification.
Claims20
A degasser for separating gas from liquid comprising:
- a substantially cylindrical tank comprising a top, a bottom, and a circumferential side wall;
- an inlet pipe for carrying a stream comprising a mixture of gas and liquid;
- and
- a vent pipe connected to the tank, wherein the vent pipe receives separated gas;
- wherein the bottom of the tank is connected to the circumferential side wall by a hinge such that the hinge at least partially opens when a sufficient mass of liquid weighs down on the bottom of the tank and at least partially closes when an insufficient mass of liquid weighs down on the bottom of the tank;
- and
- wherein the separated liquid exits the tank via an opening created as the hinge opens and creates a gap between the bottom of the tank and the circumferential side wall.
