HoSt has developed a system for upgrading biogas to a methane-rich product gas which can be injected into the gas grid. This plant is able to separate methane and carbon dioxide with a very high efficiency and to a very high methane concentration.

In this project, a small scale biogas upgrading unit is placed to upgrade biogas from the sewage plant to the quality of the natural gas. The upgraded biogas is injected in the national gas grid. The capacity of this installation is 40 m³/hr biogas. The complete upgrading unit including compressor, membranes, control, odorisation and biogas analysis is placed in a 20 ft. container.

This type of biogas upgrading installation is suitable for biogas from co-digestion plants, sewage plants and land fill sites and available in a capacity of 35 m³/hr – 500 m³/hr biogas. Depending on the local grid, the biogas can be upgraded to 89-97% CH4.
