US 2008/0289502 A1 · Cyclonic Separator and Method for Degassing a Fluid Mixture

Abstract

A method and cyclonic separator are disclosed for degassing a fluid mixture comprising a carrier liquid and one or more gaseous and/or vaporizable components, wherein: —the fluid mixture is accelerated in a throat section (6) of a vortex tube (1) such that the static pressure of the fluid mixture is decreased and vaporizable components evaporate into a gaseous phase; —the accelerated fluid mixture is induced to swirl within the vortex tube such that the fluid mixture is separated by centrifugal forces into a degassed liquid fraction and a gas enriched fraction; —the degassed liquid fraction is induced to flow into a liquid outlet conduit (4) which is located at or near the outer circumference of the vortex tube (1); and—the gas enriched fraction is induced to flow into a gas outlet conduit (3) which is located at or near a central axis of the vortex tube (1).

A method for degassing a fluid mixture comprising a carrier liquid and one or more gaseous and/or vaporizable components in a cyclonic separator, the method comprising the steps of:

accelerating the fluid mixture in a throat section of a vortex tube such that the static pressure of the fluid mixture is decreased and vaporizable components evaporate into a gaseous phase;
inducing the fluid mixture to swirl within the vortex tube such that the fluid mixture is separated by centrifugal forces into a degassed liquid fraction (L) and a gas enriched fraction (G);
inducing the degassed liquid fraction (L) to flow into a liquid outlet conduit which is located at or near the outer circumference of the vortex tube;
and
inducing the gas enriched fraction (G) to flow into a gas outlet conduit, which is located at or near a central axis of the vortex tube;
wherein the fluid mixture is first accelerated in the throat section and the accelerated fluid mixture is subsequently induced to swirl within the vortex tube.

A cyclonic separator for degassing a fluid mixture comprising a carrier liquid and one or more gaseous and/or vaporizable components, comprising:

a vortex tube having a throat section in which the fluid mixture is accelerated such that the static pressure of the fluid mixture is decreased and vaporizable components evaporate into a gaseous phase;
one or more swirl imparting vanes for inducing the fluid mixture to swirl within the vortex tube thereby inducing the mixture to be separated by centrifugal forces into a degassed liquid fraction (L) and a gas enriched fraction (G);
a degassed liquid outlet conduit which is located at or near the outer circumference of the vortex tube for discharging the degassed liquid fraction (L);
and
a gas outlet conduit which is located at or near a central axis of the vortex tube for discharging the gas enriched fraction (G);
wherein said one or more swirl imparting vanes are arranged downstream of the throat section in which the fluid mixture comprising a carrier liquid and one or more vaporizable components is accelerated.
