Weltech’s biome thane plant in France supplies gas to French distributor GrDF

0

A biomethane plant in eastern France has gone live, feeding in 70m3/h of product to the national gas grid.

Located in the Conté region, the Longchamps facility is supplying gas to the French distributor GrDF. The plant was constructed by Weltec and became operational on 5th August. Plant operator David Peterschmitt uses about 6,000 t of agricultural leftovers a year for the production of biogas from anaerobic digestion.

To ensure effective biogas processing, German plant manufacturer Weltec Biopower decided to deploy flexible, compact membrane technology. In the three-stage separation procedure, methane is separated from carbon dioxide (CO2), water vapour and other components with the help of special polymer membranes. The Weltec membrane procedure is highly efficient and delivers a methane yield of about 99%.

The upstream compression is another advantage of the procedure. In this way, the separated methane already has the needed pressure for feed-in to the natural gas grid without being compressed again. This saves costs by eliminating the need for an additional compressor and enables economic use of Weltec biogas processing even for smaller plants. This processing method also saves money in other areas: The molecules are separated at ambient temperature and without the addition of chemicals. Moreover, the membrane technology stands out with its compact setup in the container, reducing the installation overhead.
