A method of operating and cleaning a compressor comprising the following steps: passing a first fluid through the compressor, the first fluid comprising gas from a separator wherein the compressor is operating to compress the first fluid passed therethrough, mixing well fluid bypassed from upstream of the separator with the gas from the separator to produce a second fluid comprising gas and liquid wherein the gas and liquid are from at least one well; and passing the second fluid through the compressor, wherein the second fluid is passed through the compressor for a limited time period to clean a surface inside the compressor, the compressor operating to compress the second fluid passed therethrough.

Subsea compressor cleaning method wherein the cleaning liquid is retrieved from the multiphase process fluid

A gas compression system and a method of flow conditioning by a gas compression system are provided. A gas compression system includes a compact flow conditioner in a form of a flow conditioner tank and a combined multi-phase pump and compressor unit comprising an impeller configured to compress a mixture of gas and liquid, wherein the gas compression system is configured such that the gas and the liquid are separated in the flow conditioner tank, the separated gas and liquid are sucked up through the separate gas and liquid pipes and re-mixed again upstream of the impeller, and the liquid is distributed in a gas flow by Venturi effect, and wherein the Venturi effect is obtained by a constriction in the outlet pipe to the impeller, just upstream of the impeller.
