Landfill Gas Booster Station

ES2 recently designed, programmed, built, and installed a control system for an existing landfill gas booster station. Having experience both as a LFG technician and LFG turbine plant manager, I began thinking about the booster skid and how it was being applied. A question came to mind, how many other landfills across the country can use a booster station to change the flow dynamics of their well field and apply much needed vacuum to the backside their landfills? I have traveled to a variety of sites over the past few years that have a difficult time maintaining applied vacuum on the backside of their landfills, which presents difficulties like lack of gas for a renewable energy project or perhaps one of the most daunting issues for landfills – gas odor. In a perfect world your GCCS piping was sized correctly and you have plenty of collection horsepower on the front end with your blowers, and high pressure compressors if applicable. However, this is not a perfect world and sometimes we have to adapt to keep things in harmony. A booster station can increase vacuum to the backside of the landfill, reduce strain/parasitic load on your collection blowers/compressors, and give you the flexibility to change the flow dynamics of your well field with a simple pipe and valve manifold pre and post booster station. All things to consider when upgrading or modifying an existing gas collection and control system.
