A seal gas pressure booster system for use with a gas compressor, particularly of the type used for boosting pressure in gas transmission, process or utility industries and which contains pressure about the shaft/casing interface with the use of dry gas seals. Seal supply gas is supplied from the discharge side of the compressor. During normal operation, sufficient head across the compressor exists to supply the necessary flow of seal supply gas against the restrictions provided by the filters, interconnections and components in the seal gas supply syste...
1. In combination, a turbomachine having a rotor therein, said rotor having a dry gas seal associated therewith, and a primary seal gas supply system adapted to supply a flow of seal gas to said dry gas seal when a sufficient pressure differential exists as to maintain that flow, said primary seal gas supply system having an upstream section adapted to be connected to a primary source of said gas and a downstream section connected to said dry gas seal, one-way valve between said upstream and downstream sections preventing a back flow of gas from the down...
