Project Highlights

  • Plant expansion to increase its capacity to process landfill gas from its current rate of 8,000 scfm. to 12,000 scfm. while also making provisions for a future project to bring the capacity to 16,000 scfm.
  • Replacement of existing CO2 removal system will increase plant efficiency currently at 90% to over 99%
  • Additional equipment required included centrifugal blowers, positive displacement blowers, a second H2S removal system, pumps, chillers, heat exchangers, an incinerator, compressors along with all associated instrumentation, valves and specialty items
  • 10 MVA, 13.8kV capacity added to the electrical distribution system
  • New electrical building designed with MV and LV rooms with motor controls for (7) MV compressors with VFDs and Soft Starters 400 – 1250 hp.
