Abstract: A method and apparatus for producing gaseous and liquid components from one or more multi-phase streams in one or more pipelines. The method includes passing a first multi-phase stream along a first pipeline, and passing the first multi-phase stream through a first slugcatcher system to provide a first gaseous component stream and at least one first liquid component stream. The method also includes selectively opening a first branch pipeline from the first pipeline upstream of the first slugcatcher system to pass at least a fraction of the first multi-phase stream through the first branch pipeline to provide a first branch multi-phase stream, and passing at least a fraction of the first branch multi-phase stream to a first gas/liquid separator to provide an overhead gaseous stream and a bottom liquid stream.

Abstract: The present invention provides a method of producing gaseous and liquid components from one or more multi-phase streams in one or more pipelines and an apparatus therefore, the method comprising at least the steps of: (a) passing a first multi-phase stream along a first pipeline; (b) passing the first multi-phase stream through a first slugcatcher system to provide a first gaseous component stream and at least one first liquid component stream; (c) selectively opening a first branch pipeline from the first pipeline upstream of the first slugcatcher system to pass at least a fraction of the first multi-phase stream through the first branch pipeline to provide a first branch multi-phase stream; and (d) passing at least a fraction of the first branch multi-phase stream to a first gas/liquid separator to provide an overhead gaseous stream and a bottom liquid stream.
