Down-stream from Chemrec’s existing development plant for black liquor gasification, Chemrec has engineered and constructed a DME plant using novel synthesis technology from Haldor Topsoe. Synthesis gas is produced in DP-1 plant (pressurized entrained flow black liquor gasifier). The synthesis gas is purified in activated carbon filters and in an amine wash. The purified synthesis gas is passing a water gas shift before methanol and DME reactors.
