In-Line Flow Separation of Fluids in a Pipe Separator

摘要

An in-line flow separator ( 1 ) comprises an uphill section ( 2 ) of pipeline which, in use, carries a gravitationally stratified flow of a first liquid ( 3 ) and a second denser liquid ( 4 ). The second liquid ( 4 ) forms a sump ( 5 ) extending uphill from the foot of the uphill section ( 2 ), and an interface between the first and second liquids on the uphill section is inclined from the horizontal. An extraction port ( 6 ) in the pipeline extracts the second liquid from the sump.
