Abstract
A gas recycling system, for use with a gas compressor having an inlet for gas at a relatively low pressure and an outlet for gas at a relatively high pressure, a gas-lubricated, non-contacting mechanical seal to which relatively high pressure may be fed from the gas compressor, the system including both a seal gas booster and a vent recycle system, the system further including means for feeding seal gas from the gas compressor to a conditioning system and from the conditioning system to the mechanical seal and an activation device to activate the gas booster once the gas difference exceeds a pre-determined level.
Claims13
A gas recycling system for use with a gas compressor having an inlet for gas at a low pressure and an outlet for gas at a high pressure, a gas-lubricated, non-contacting mechanical seal to which high pressure is able to be fed from the gas compressor, said gas recycling system comprising both a seal gas booster and a vent recycle system, said gas recycling system further comprising means for feeding seal gas from the gas compressor to a conditioning system and from said conditioning system to said mechanical seal, and means for activating the seal gas booster once a gas difference exceeds a pre-determined level.
A method for recycling gas leaking from a gas-lubricated, non-contacting mechanical seal, comprising the step of subjecting the gas leaking to a gas recycling system for use with a gas compressor having an inlet for gas at a low pressure and an outlet for gas at a high pressure, a gas-lubricated, non-contacting mechanical seal to which high pressure is able to be fed from the gas compressor, said gas recycling system comprising both a seal gas booster and a vent recycle system, said gas recycling system further comprising means for feeding seal gas from the gas compressor to a conditioning system and from said conditioning system to said mechanical seal, and means for activating the seal gas booster once a gas difference exceeds a pre-determined level.
