Cleaning of pressurized condensable gas

Abstract

Abstract A compressor system such as a refrigerating system comprising a compressor for discharging a condensable gas in the gaseous phase thereof, means for introducing oil into the compressor and an oil separator for separating oil from the discharged gas and return the oil to said introducing means, characterised in that the oil separator is divided in a primary separator having in known manner an oil colllection chamber from the primary separator and containing an amount of an oil rest out-washing liquid consisting of the gas in the condensed phase thereof, the secondary separator including means for bringing the gas into washing contact with the liquid for washing out at least most of the oil still remaining in the gas, the secondary separator having a gas outlet from which the gas is fed to a condenser for condensing at least some of the gas, the condenser having a receiver for the condensed gas, this receiver being connected to the secondary separator so as to be operable to continuously or intermittently supply condensed gas to the secondary separator, this separator further having an outlet for condensed gas and means for continuously or intermittently supplying condensed gas from this outlet to means for injecting the condensed gas into the flow of gaseous gas passing or leaving the compressor, before or when the gas enters the primary oil separator.
