A low pressure separation system comprising a separator for receiving fluid from a well, and a surge vessel for receiving liquid from the separator, characterised in that when the liquid reaches a predetermined high level in the surge vessel, a valve on the equalisation pipe connecting the surge vessel to the separator is closed and high pressure gas is directed into the surge vessel by opening a valve or a gas pipe, forcing: the liquid out of the surge vessel to a production header via a liquid outlet, a when the liquid drops to a predetermined low level in the surge vessel, the valve on the gas pipe is closed, and the valve on the equalisation pipe is opened to equalise the pressure between the surge vessel and the separator. |
