The integration of an amine scrubber for CO2 removal with the WoodRoll® system was discussed in a meeting on the 14th of October at Lund University.

The WoodRoll® process produces a clean syngas that after methanation consists of roughly 50% methane and 50% carbon dioxide. The carbon dioxide has to be removed in order to achieve biomethane of vehicle fuel quality. Nice features of the thermochemical conversion path are the absence of hydogen sulfide since sulphur is removed upstream of the methanation reactor, and that the methanation process provides sufficient heat for regeneration of the scrubber liquid.
