Short description
In Denmark, the amount of biogas in the distribution grids increases. When bio natural gas (biomethane) from distribution grids is fed into the transmission grid, the concentration of odorant present in the gas needs to be reduced to accepted trace amounts max (1.0 mg THT/Nm3). The removal of the odorant, tetrahy-drothiophene (THT), will be executed by a deodorization unit, at the place of injection into the transmission system. The Framework Agreement covers purchase of a number of deodorizing units for injection of upgraded biogas from the distribution grid into the natural gas transmission grid in Denmark. The deodorization units for reduction of THT in the source gas has the requirements of the export grids will be included in the reverse flow plant’s facilities. The capacity is within 5.000 Nm3/hr., to 30.000 Nm3/hr., and maximum inlet pressure 19-60 barg. For further details concerning the purchase, reference is made to the appendices to the tender documents.
