Abstract
A gas/liquid separator includes a housing and a rotatable degassing chamber in the housing. Liquid containing gas is fed into the housing and through an annular liquid inlet conduit which opens into the chamber. Degasified liquid is discharged from the rotating chamber through one or more discharge passages in the circumferential wall of the chamber due to centrifugal force on the liquid in the rotating chamber. An upstream portion of each discharge passage is farther radially from the chamber axis of rotation than is the exit port of the passage. This forms a column of liquid in each discharge passage which, in turn, provides a gas seal between the inside and the outside of the chamber to prevent separated gas from accompanying the liquid out of the chamber. In essence, the discharge passage incorporates a liquid sealed trap. In applications involving separation of gas from highly viscous liquids, such as drilling mud, the interior of the chamber can contain baffles which expose a large surface area of the liquid to the low pressure in the chamber. Gas withdrawn from the liquid flows from the chamber through an axial conduit within the annular liquid inlet conduit.
