After an eight month construction period, one of Germany's largest biomethane refineries has gone live in the Altmark Industrial and Commercial Zone and has been supplying the public grid since May. With four digesters of 4,900 cubed meters, six digestate storage units of 5,000 cubed meters and a liquid reservoir, the Nordmethan plant from Vechta, Lower Saxony, produces 1,650 standard cubed meters of raw biogas an hour. Fifteen percent of this raw material is used for the heat needs of the plant, which was designed by Weltec Biopower.
By using chemical amine treatment, the gas converts about 700 standard cubed meters of processed biomethane an hour, with a methane content of 99 percent - enough to supply 5,000 homes with power and heat. For this purpose, a solid matter dosing feeder loads maize silage, whole-plant grain, sugar beets, dry chicken dung, chicken manure, liquid manure and water as substrates into the stainless-steel digesters. In total, the substrates delivered by local farmers amount to more than 70,000 tons a year.
"The biomethane refinery in Arneburg demonstrates that we must provide the right answer to the growing demand for biomethane for the various utilization paths. This sustainability is also highlighted by the fact that Nordmethan has created ten regular jobs and two training jobs, "says Jens Albartus, Director of Weltec Biopower.
