Method and apparatus for splitting two-phase flow at pipe tees

摘要

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.
