Abstract
A system for separating liquid and gas flowing through a multiphase pipeline, said system comprising: A riser (8) having an upper end (2) and a lower end (10), said riser being at its lower end configured to receive fluid from said multiphase pipeline (4) and having means for delivering (5) of gas at its upper end, said riser further comprising valve means (6) for adjusting the flow at which the gas is delivered through the upper end of said riser; a pipe (7) to be arranged outside or inside the riser, said pipe having an upper part (3) and a lower part (9), where the lower part is connected to or inserted into the riser, thereby creating a liquid flow path between the riser and the lower part of the pipe, said pipe having a liquid intake (11) configured to receive liquid from a liquid column in said riser, and said upper end of said pipe being configured to deliver said liquid, said pipe further comprising means for adjusting the flow at which said liquid is delivered through the upper end of said pipe; level measuring means adapted for measuring the position of a surface (18) of said liquid column in said riser; control means capable of controlling said valve means, such that the…
