摘要
The application discloses a method for the pre-processing of a raw-methanol product gas that contains methanol, water, waxes (paraffins) and rests of synthesis gas, the method comprising the steps of cooling the product gas, partly condensing the product gas to a temperature over the melting point of the waxes, separating the condensate from the gas phase to obtain a first, wax-containing condensate stream, condensing the gas phase further by cooling to a temperature under the boiling point of methanol to obtain a second substantially wax-free condensate stream, and optionally separating the wax from the first condensate stream and combining the two condensate streams for further work-up. A plant for the pre-processing of a raw-methanol product gas is also disclosed.
