Abstract
There is disclosed a gas-liquid separator of the type imparting a swirl to the incoming gas-liquid mixture in order to centrifugally throw liquid droplets out of a main gas flow path. The swirling mechanism comprises a helical screw. The capacity of the separator is selectively reduced by blocking off one or more of the separate and distinct flow paths provided between the flights of the helical screw.
Claims7
A gas-liquid separator comprising:
- a collection vessel including a gas outlet and a liquid outlet;
- an inlet structure including:
- an inlet conduit opening into the vessel having an inlet end providing an inlet opening and means on the inlet end for connection to a mixture flow line for delivering mixture from the flow line to the inlet conduit;
- and
- a corkscrew mechanism in the inlet conduit providing a predetermined effective cross-sectional flow area for centrifugally swirling an incoming mixture;
- means for reducing the predetermined effective cross-sectional area of the corkscrew mechanism and thereby increasing the velocity of a given volumn of mixture through the corkscrew mechanism, comprising:
- a blocking member insertable through the inlet opening of the inlet conduit when the flow line is removed from the connection means;
- and
- means retaining the blocking member;
- the inlet opening of the inlet conduit being sufficiently large to pass the blocking member.
