Abstract

A method of processing a multiphase well effluent mixture comprises : transferring the mixture (L+G) via a multiphase well effluent flowline (2) to a gas liquid separator (1) in which the multiphase well effluent mixture is separated into substantially gaseous and liquid fractions; transferring the substantially liquid fraction (L) into a liquid flowline (6) in which a liquid pump (7) is arranged; transferring the substantially gaseous fraction (G) into a gas flowline (8) in which a gas compressor (9) is arranged; protecting the gas compressor (9) against liquid and/or pressure surges due to low gas flow rate and/or backflow of compressed gas by recirculating a recycled gas stream (Ghot) via a gas recycling conduit (10) through the gas compressor in response to detection of the onset of a liquid surge in the multiphase well effluent mixture and/or of a pressure surge due to low gas flow rate and/or a high pressure differential across the gas compressor (9); and cooling the recycled gas stream by contacting recycled hot gas (Ghot) with relatively cold liquid L within the separator (1) or associated flowlines (2, 6) preferably using an array of gas injection nozzles (14) which inject the hot gas (Ghot) as finely dispersed gas bubbles into the liquid (L).
