METHOD OF BYPASSING A PIPELINE IN A MULTIPLE PIPELINE SYSTEM

摘要

The present invention relates to an apparatus and method of producing gaseous and liquid component streams from at least two multi-phase streams in at least two pipelines, the method comprising at least the steps of : (a) passing a first multi-phase stream along a first pipeline (10) and through a first slugcatcher system (12); (b) passing a second multi-phase stream through a second pipeline (20) and a second slugcatcher system (22), (c) passing a first pig (9) down the first pipeline (10) to create a first pig-slug mass in the first pipeline; and (d) passing at least a fraction of the first multi-phase stream upstream of the first pig-slug mass to the second pipeline (20) along a crossover line (30).
