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, double mechanical seal to which relatively high pressure gas may be fed from the compressor, the gas recycling system including a seal gas booster for boosting the pressure of the gas between the compressor and the double mechanical seal.
Claims15
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, double mechanical seal to which a high pressure gas is able to be fed from the gas compressor, said gas recycling system comprising a seal gas booster for boosting pressure of a gas between the gas compressor and the double mechanical seal.
The gas recycling system according to Clam 8, further comprising means for activating said seal gas booster when the pressure difference exceeds a predetermined 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 compressor having an inlet for gas at a low pressure and an outlet for gas at a high pressure, a gas-lubricated, non-contacting, double mechanical seal to which a high pressure gas is able to be fed from the gas compressor, said gas recycling system comprising a seal gas booster for boosting pressure of a gas between the gas compressor and the double mechanical seal.
