摘要： A method of cleaning deposited solid material from a fouled portion of a gas compressor (6) whilst the gas compressor (6) is in situ in a natural gas processing system (1) is provided. The method comprises the steps of supplying a liquid cleaning agent to a gas inlet of the gas compressor (6), the liquid cleaning agent being capable of removing the deposited solid material; passing the liquid cleaning agent through the gas compressor (6) to a gas outlet of the gas compressor (6), wherein at least a portion of the cleaning agent remains in a liquid state as it passes through the fouled portion of the gas compressor (6); and recovering a fluid containing removed material that is output from the gas compressor (6) so as to prevent the removed material reaching one or more gas processing stages of the gas processing system (1) downstream of the gas compressor (6).

摘要： A method and corresponding gas processing system for cleaning deposited solid material from a fouled portion of a gas compressor whilst the gas compressor is in situ in a natural gas processing system are provided. Cleaning of a gas compressor is achieved by accumulating liquid removed from cooling gas used for cooling the gas compressor and supplying the accumulated liquid to an inlet of the gas compressor in order to remove deposited solid material from the gas compressor. The cooling gas is extracted from an intermediate stage of the gas compressor.

摘要： There is provided an apparatus 30 and method for conditioning the flow of a mixed phase flow from a supply pipe 101 from a hydrocarbon well. The apparatus 30 comprises an elongate reservoir 11 having a first end for receiving a multi-phase fluid flow from the supply pipe and a second closed end, there being provided a gas outlet 02 from the upper part of the first end, a liquid separation region downstream of the first end, and a liquid outlet 12 from the lower part of the liquid separation region; and a gas-liquid mixer to which the gas and liquid outlets are connected such that the separated gas and liquid may be recombined. The reservoir 11 may accommodate surges of liquid such that the flow rate from the liquid outlet is relatively invariant over time compared to that of the flow received by the apparatus.
