METHOD AND SYSTEM FOR SUPPRESSING AND CONTROLLING SLUG FLOW IN A MULTI-PHASE FLUID STREAM

摘要

A method and system for suppressing and controlling liquid slugs and gas surges in a multiphase fluid flow line make use of a gas liquid separator (9) and a gas valve (16) in the gas outlet (14) and a liquid valve (15) in the liquid outlet (13) of said separators, which valves (15, 16) are adjusted automatically in response to variations of one of more selected control variables, such as QGAS, QLiquid, QLiquid+Qgas, Lliquid, P, and the control variable is changed automatically from time to time if one or more selected control variables reaches a pre-set threshold value.
