• Abstract:

  Biogas from landfills and wastewater treatment plants (WWTP) is a raw material for the production of energy and new products. When it leaves the digester, biogas is a dirty gas with harmful components for its use (NH3, siloxanes, halogenated hydrocarbons, BTEX, VOCs, H2S, etc.). Among the components of greatest incidence, both in the energetic use of biogas and in its use for the production of biomethane, are the siloxanes due to the damage they cause, both in machines for the production of energy and in the technologies used for the production of biomethane.
  Several technologies for biogas cleaning are currently available on the market. The BTS-MPdry-Siloxa technology. It is a multipurpose technology based on the combination of operations developed by BGasTech for the removal of siloxanes present in biogas. The technology has two basic stages. A coarse removal stage and a refining stage that produces a raw material quality biogas with a high degree of cleanliness and low OPEX that guarantees the proper use of the biogas for any purpose.
