Bright Biomethane has developed an installation in Assen for upgrading biogas to a methane-rich product gas which can be injected into the gas grid. This installation 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 Nm³/hr biogas which is upgraded to 20 Nm³/hr biomethane. The complete upgrading unit including compressor, membranes, control, odorisation and biogas analysis is placed in a 20 ft. container.
