Landfill Gas Blower Control System – Pennsylvania

Process Description:Landfill Gas Blower

Landfill gas is drawn from the well field using (2) blowers on variable speed drives (VFDs). The blowers feed landfill gas to (1) 2000 CFM enclosed John Zink flare. Wellfield pressure (vacuum) is controlled with a PID control loop, modulating the designated VFD and blower speed based upon feedback from a wellfield pressure transmitter. Blower surge protection was included in the PLC logic and alarms are transmitted on a wireless transmitter to SCADA system. The PLC logs all process variable data to a memory card.
