Biomethane plant

Biogas upgrading and liquefaction of bioLNG biomethane

From biomass to biomethane

The biogas produced from the fermentation of organic waste (sewage sludge, agricultural and livestock waste, urban waste FORSU) can be purified to obtain biomethane, which can be used as fuel for vehicles or for injection into the natural gas network.

Why produce biomethane?

Biogas upgrading plant

Our biogas purification/upgrading plant for the production of biomethane uses a hybrid system that combines Water Scrubber and Membrane technologies.

This system is based on optimizing the process through the combination of a water wash stage and a double membrane purification stage.

Compared to other upgrading technologies, the hybrid system allows for the optimization of operating costs (-10% compared to 3-stage membranes) and continuous production at maximum yield, with a methane recovery greater than 99.5%.

BioLNG biomethane liquefaction plant

The biomethane liquefaction plant produces a stable, high-quality bioLNG for transport.

  • The system can produce bioLNG down to -200°C and at low operating pressures (2-4 barg or lower);
  • High energy efficiency, compared to other cryogenic processes;
  • Extremely environmentally friendly process, does not contribute to ozone layer depletion, greenhouse effect, and does not release harmful or toxic gases;
  • Efficient removal of non-condensable gases (N2, O2, H2, etc.);
  • “Plug and Play” and modular design (modules from 1 to 20 tpd);
  • Scalable for future growth (allows growth/investment based on demand);
  • Integrated solution “Purification + Liquefaction”;
  • No process fluid in contact with mechanical parts, avoiding any form of contamination;
  • High operability (>8,400 hours/year);
  • Intrinsically redundant design with multiple modules for each liquefaction system;
  • Equipment approved by BV, ABS, and USCG.
