A mixture of fluids is conveyed from a hydrocarbon reservoir and comprises
gas and slugs of liquid. The mixture is passed through a slug catcher
vessel (12) which temporarily retains the slugs of liquid. The gas is
passed through a gas compressor (18) and the resulting pressurised gas is
then conveyed to a remote location. When a liquid slug is detected in the
slug catcher vessel (12), liquid is drawn from the vessel by an injector
device (24) and entrained into the flow of gas downstream of the gas
compressor (18) until the level of the interface between the gas and
liquid in the vessel reaches a sufficiently low level. The system may
alternatively be configured to accommodate a flow of liquid containing
slugs of gas.
