ABSTRACT:
Hot gas bypass of compressed fluid is accomplished using standard components of an oil separation circuit. In this method, an electronically controlled valve, which is selectively opened and closed for returning oil accumulated in the oil separator is also selectively opened when a determination is made that hot gas bypass is desired. This electronically controlled valve is placed in the oil separator return line. When the valve is opened, hot gas is bypassed from compressor outlet into compressor inlet through the oil separator.
