The success of separation using the ValorGas® system is conditioned to an optimal biological desulphurisation pretreatment for impurities elimination present in the biogas, which are a limitation for the suitable use of the membranes.

BIMEO provides the most leading biological pretreatment systems that allow substantial savings in process costs and maximum desulphurisation performance, as well as the removal of volatile organic compounds usually found in biogas.

The selection of the proper pretreatment for the process depends on the biogas quality to be upgraded, as well as the addition of thermal drying, biological desulphurisation and refining by activated carbon adsorption.

The optimized combination of biogas cleaning technologies leads to:

  • Better results in biomethane quality
  • Better energy efficiency
  • Low operating costs
  • Low environmental impact
