<p>In a chemical process reaction (the 'main'-process) that uses methanol as a starting material or in which methanol is present in the product mixture, some of the methanol is converted into dimethyl ether, some of the water concurrently formed with the dimethyl ether is removed and the dimethyl ether-containing stream is fed to the 'main' process. The 'main' process may be the production of alcohols by a reaction involving carbon monoxide.</p> |
