Abstract:
Dry pumps are used to pump a variety of gas mixtures from the semiconductor industry. The present invention provides a liquid ring pump located between the dry pump and an abatement device to remove soluble corrosive materials prior to the exhaust gases entry to the abatement device, the work fluid exhausted from the liquid ring pump being separated from the gas prior to entry to the abatement device.

Claim (Index 1):
An apparatus for evacuating a gas stream comprising a corrosive fluid exhausted from a processing chamber, comprising:\n a dry pumping arrangement for evacuating the gas stream comprising a corrosive fluid from the processing chamber; a liquid ring pump arranged for evacuating the gas stream comprising a corrosive fluid from the dry pump and at least partially reducing the corrosive fluid content of the gas stream by dissolving said corrosive fluid into the service liquid of the liquid ring pump; a separator for separating, from the service liquid and remaining gas stream mixture exhausted from the liquid ring pump, the remaining gas stream; and an abatement arrangement for treating the separated remaining gas stream exhausted from the separator.
