Biogas Purification Project in Qingdao West Coast Eco-industrial Park

Dual-benefits ofenvironmental protection and energy, the essential path for green development




  • Adopt the process of "wet desulfurization + dry desulfurization + biogas pressurization + PSA purification + voltage regulation for grid - connection". The average daily biogas treatment capacity is 20,000 m³, and the daily natural gas production is about 15,600 cubic meters.
  • After biogas purification, it meets the technical indicators of Class - l gas in Natural Gas(GB17820-2018).
  • The biogas production in each vein industrial park of SUS ENVIRONMENT ranges from 10,000 to 35,000 m/day. The high - value utilization of anaerobic biogas is realized through large -scale biogas purification in syergy with incineration plants and kitchen waste treatment plants.
  • In line with China "dual - carbon emission reduction" policy, it reduces carbon emissions by l,560 tons per year.
