The object of the present invention is to provide a compression system to effectively compress contaminated gas containing water and other corrosive substances (natural gas) without suffering any adverse effects caused by toxic substances, including impurities, and which includes a path which heats the compressor using gas with a low dew-point temperature, such as water free gas or purified gas from outside the system, that is substantially free of water, or discharged gas after having been compressed by the compressor, a separator provided upstream of the suction section of the compressor, which separates water the the like from natural gas by cooling and condensation, and a dew-point maintaining arrangement for maintaining the discharged temperature of gas from the compressor above the dew-point temperature of the compressed gas when compressing natural gas from which water has been separated by the separator and characterized in that, when direct compression of the actual gas (contaminated gas) is necessary, a heating operation is carried out by a gradually increasing the pressure of the gas discharged from the compressor by controlling the suction pressure of the compressor, by adjusting the opening of a pressure control valve on the return pipe, and after the hearing operation, the actual compressing operation of natural gas is not affected, and a stable continuous operation is enabled due to a smooth switchover.
