ABSTRACT:
The invention comprises supplanting the usual, single, electrically-operated, blowdown valve, located on the receiver/separator tank of a gas compressor system with a pair of valves operatively arranged in parallel. The one valve operates normally in the manner of the supplanted valve, albeit with reduced venting capacity, and the other is held closed on starting of the compressor. This restricts the venting of the tank and causes its quick pressurization, to induce prompt oil injection for the compressor. A sensor detects the injection oil temperature and when the latter has achieved a given setpoint, the other, vent-restricting valve is opened. Accordingly, the method comprises sensing the temperature of the oil injected into the compressor and holding one of the paired venting valves closed until the oil temperature reaches the aforesaid given or predetermined setpoint.
