Framework agreement for deodorization units with THT analyser

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) before the gas enters the transmission grid. The removal of odorant, tetrahydrothiophene (THT), will be executed by a deodorization unit, at the place of injection into the transmission system. This Framework Agreement covers purchase 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 odorant (THT) in the source gas to the requirements of the export grid will be included in the reverse flow plant facilities. The capacity is within 5.000 Nm3/hr., to 15.000 Nm3/hr., and maximum inlet pressure is within 19-60 barg.
