Patent ID: 7980753

Claim:
A processing system, comprising: a vacuum pump system fluidly coupled to a vacuum line, the vacuum line configured to be capable of receiving a processing fluid removed from a processing station; wherein the vacuum pump system comprises: a liquid ring pump having a suction port fluidly coupled to the vacuum line, wherein the liquid ring pump is configured to be capable of receiving from the processing station a multiphase processing fluid stream; a sealant fluid tank fluidly coupled to an exhaust port of the liquid ring pump and comprising one or more devices configured to be capable of removing liquid from a multiphase stream output by the liquid ring pump through the exhaust port; wherein the sealant fluid tank is adapted to provide the liquid ring pump sealant fluid during operation of the liquid ring pump; and a fluid reclamation system fluidly coupled to an outlet of the processing station configured to be capable of returning at least a portion of the processing fluid removed from the processing station to a point upstream from the processing station for reuse at the processing station, and a chemical concentration control system configured to be capable of a) monitoring a concentration of the sealant fluid contained in the tank and fed to the liquid ring pump during the operation of the liquid ring pump; and b) performing at least one of: i) selectively adjusting a concentration of the sealant fluid; and ii) directing the sealant fluid to drain.
