Methanol purification The main purpose of the methanol purification process is to increase the concentration and purity of raw methanol, generated in the methanol liquefaction plant into commercial grade biomethanol. The acceptable quality for commercial grade methanol is defined according to the IMPCA (International Methanol Producers and Consumers Association) methanol reference specifications. A pulp mill
