Abstract:
A pressure stabilization system for damping pressure variations in a process (10) discharging an effluent gas stream, in which the process is pressure-sensitive and downstream pressure variations can adversely affect the upstream process, comprising a motive fluid driver (38) to receive the effluent gas stream, and means (3) for sensing a pressure characteristic of the effluent gas stream and adjusting the flow of the effluent gas stream to damp pressure fluctuations. The pressure stabilization system may further comprise: (i) a variable frequency drive (170) for operating the motive fluid driver at a variable rotational speed; (ii) a pressure transducer monitor (186) for monitoring the pressure characteristic of the effluent gas stream and generating a pressure transduced signal; and (iii) a proportional integral derivative controller (188) coupled with the pressure transducer monitor (186), and responsive to the pressure transduced signal to adjust the variable frequency drive to damp pressure fluctuations.
