Abstract
A method and apparatus for diverting into a branch line a portion of a gas-liquid flow stream from a two-phase flow trunk line. Each of two or more takeoff pipes withdraw a two-phase portion of the trunk line flow stream and transmit it to a single common branch line. The takeoff pipes are oriented to produce branch line flow of predetermined quality. The quality of branch line flow may be monitored and control valves positioned in one or more takeoff pipes and in the branch line to facilitate branch line flow of variable quality and rate.
Claims5
A process for diverting a stream of a flowing fluid having at least one gas phase and at least one liquid phase from a pipeline into a branch line, which comprises:
- (a) withdrawing a first portion of said fluid from said pipeline in a generally upward and radially outward direction, and at a first flow rate;
- (b) simultaneously withdrawing a second portion of said fluid from said pipeline in a generally downward and radially outward direction, and at a second flow rate;
- (c) combining said first and second portions into said branch line;
- and
- (d) regulating said first and second flow rates so that said first and second portions combine to form a stream of fluid in said branch line at a predetermined, desired quality.
