Blue Moutain Biogas Power Generation Plant, Utah

The Blue Mountain Biogas plant operates by taking diluted hog manure from the ‘finishing’ barns into an influent basin. From there it is transferred to a heat exchanger facility and then into two in-ground digesters. The resulting methane gas is vented into a scrubber tower where impurities are removed, then into two gas compressors where the gas is dried and pressure boosted to feed the two engines. The Blue Mountain biogas plant has the capacity to generate 3.2Mw from two 1.6Mw engines, this being sufficient electricity to power approximately 3,000 homes. They expect to produce 25 million kW hours a year by operating on a 24/7 schedule.
