  • Flow-stabilized wet scrubber system for treatment of process gases from semiconductor manufacturing operations
    Patent number: 5851293
    Abstract: A flow stabilization system for damping pressure variations in a process discharging an effluent gas stream, in which the process is pressure-sensitive and downstream pressure variations can adversely affect the upstream process, said system comprising a motive fluid driver constructed and arranged to receive the effluent gas stream from the process, and means for sensing a flow characteristic of the effluent gas stream and responsively adjusting the flow of the effluent gas stream to damp pressure fluctuations in the process.
