The biggest biogas plant in the northern part of Jutland has just been inaugurated. AVK has delivered 36 knife gate valves for the plant, which is the size of 12 soccer fields.
The new plant will primarily be producing biogas from local cattle and pig manure, industrial waste products, and food leftovers. The plant is expected to treat 300,000T of biomass every year and it will be able to supply the natural gas network with approximately nine million cubic metres bio methane.
The production of biogas is initiated when fresh manure is mixed with industrial waste and food leftovers in the recipient container. Then the biomass is pumped into the reactors where it is heated to approximately 52 degrees. The biomass is kept in the reactors while the manure ferments and the gas is formed. The gas is discharged from the reactor containers and the degassed manure is pumped to storage containers where farmers can pick it up.
About 30 AVK valves are installed in the manifold where the manure is picked up and carried around the plant. Additionally, six valves are installed to fill and empty the plant's three heating modules.
