A gas recovery system designed to recover vent gas emanating from a gas processing system and return the gas to the processing system. The gas recovery system includes a pressurized motive gas that is directed through a vacuum generating apparatus. The vacuum suctions the vent gas into the vacuum generating apparatus and mixes the vent gas with the motive gas to create a mixed gas stream. The mixed gas stream is transported away from the vacuum generating apparatus by a mixed gas outlet line. A vent gas pressure regulator is fluidly connected between the vent gas supply line and the mixed gas outlet line. The vent gas pressure regulator maintains the vent gas supply line pressure above a predetermined pressure.
