ABSTRACT:
Methanol is converted from syngas at high temperatures and pressures. The gas stream leaving the converter, at 300.degree. to 500.degree. C., above atmospheric pressure--usually between 750 to 7000 pounds per square inch, has besides the unreacted permanent gases of the syngas and others, methanol and water as well as other liquid impurities. Based on the weight of methanol, water may be present in from 0.5 to 20%, also small amounts of higher alcohols, dimethyl ether, etc. Condensation gives an aqueous liquid, from which the water must be separated if the methanol is to be used as a motor fuel. When this amount of water is low e.g. 0.5 to 12% this may be separated by adsorption most economically from the gas before condensation of the methanol. The energy in this gas stream at a high temperature and pressure above the ambient may be used to dehydrate completely the methanol, by the use of a conventional desiccant.
