Abstract
Abstract The invention provides a separator for separating a vertical flowing gas-liquid mixture. The separator comprises a vertically elongated cylindrical chamber into which the mixture is introduced vertically. Connected to the inlet conduit within the chamber are a pair of flow diverters which change the flow pattern from a vertical cylindrical configuration to a pair of sheets directed horizontally against the inner walls and circumferentially around the vertical axis of the chamber. The diverters present a continuous geometry to the flow in order to reduce head losses. Inside each diverter are a number of guide vanes distributing the flow evenly through the diverters. The separated gas exits through an outlet at the top of the chamber while the liquid exits at the bottom.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
189 words
A gas-liquid separator comprising an elongated substantially vertically disposed cylindrical chamber having an upper gas outlet and a lower liquid outlet, an inlet conduit extending coaxially upwardly into the chamber through a lower wall thereof for directing a gas-liquid mixture upwardly into said chamber, at least one flow diverter disposed within said chamber, each diverter comprising an inlet portion communicating with said inlet conduit, a curvilinear transitional tubular portion curving smoothly radially outwardly from a substantially vertical orientation at the inlet portion and terminating with a horizontally oriented outlet portion that extends circumferentially around a substantially vertically extending axis and wherein said outlet portion is vertically elongated such that the mixture leaves in a sheetlike configuration against an inner surface of the chamber thereby inducing a circular flow of gas in a given direction in said chamber, each diverter having a substantially constant cross-sectional area throughout its length, and a plurality of spaced vanes disposed within and extending substantially throughout the total length of each diverter for dividing said diverter into a plurality of channels, said channels being disposed substantially vertically with respect to one another at said outlet.
Claim 2
Dependent Claim
189 words
A gas-liquid separator comprising an elongated substantially vertically disposed cylindrical chamber having an upper gas outlet and a lower liquid outlet, an inlet conduit extending coaxially upwardly into the chamber through a lower wall thereof for directing a gas-liquid mixture upwardly into said chamber, at least one flow diverter disposed within said chamber, each diverter comprising an inlet portion communicating with said inlet conduit, a curvilinear transitional tubular portion curving smoothly radially outwardly from a substantially vertical orientation at the inlet portion and terminating with a horizontally oriented outlet portion that extends circumferentially around a substantially vertically extending axis and wherein said outlet portion is vertically elongated such that the mixture leaves in a sheetlike configuration against an inner surface of the chamber thereby inducing a circular flow of gas in a given direction in said chamber, each diverter having a substantially constant cross-sectional area throughout its length, and a plurality of spaced vanes disposed within and extending substantially throughout the total length of each diverter for dividing said diverter into a plurality of channels, said channels being disposed substantially vertically with respect to one another at said outlet.
Claim 3
Dependent Claim
55 words
The apparatus of claim 1 wherein the outlet portion of each diverter has a rectangular crosssection defining an upper wall, a lower wall and a radially inner and radially outer wall with respect to the vertically extending axis, and wherein the radially outer wall extends circumferentially and vertically beyond the inner, upper and lower wall.
Claim 4
Dependent Claim
35 words
The apparatus of claim 1 wherein said vanes are obliquely oriented with respect to a horizontal plane with the radially outermost edges of the vanes being higher than the radially innermost edges of the vanes.
Claim 5
Dependent Claim
48 words
The apparatus of claim 1 including a liquid carry-over impeder disposed within said chamber above said diverter and comprising a plurality of overlapping circumferentially disposed blades, said blades being inclined such that circular flow of a gas in said chamber is reversed from that induced by the diverter.
Claim 6
Dependent Claim
44 words
The apparatus of claim 1 having two flow diverters, each having adjacent rectangular inlet portions which combined form a square section, the mixture inlet conduit having an upper adaptor portion having a square section for connection with the combined pair of rectangular inlet portions.
