Title:
A METHOD OF DRAINING A FLUID TANK IN A FLUID SEPARATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/062419
Kind Code:
A3
Abstract:
A method of draining at least one liquid collector (3, 4) in a system for separating and collecting liquid contained in gas from a reservoir, wherein the at least one liquid collector (3, 4) is connected to an outlet (6) from a compressor (5), and a recirculation circuit (10) between the outlet (6) of the compressor and an inlet (1) from the reservoir to a liquid separator (2) to which the at least one liquid collector (3, 4) is connected downstream thereof, and which outlet (6) is connected downstream to a transport pipe (7). The method comprises raising the pressure of the liquid in the at least one liquid collector (3, 4) to a higher pressure than the pressure in the inlet pipe (1) or the transport pipe (7), and draining the liquid in the at least one liquid collector (3, 4) upstream either to the inlet pipe (1) or directly to the liquid separator (2) via a first drain line (K), or alternatively downstream to the transport pipe (7) via a second drain line (13).
