Abstract
A process for separating undesired, in particular acidic gas constituents from a raw gas, in particular raw synthesis gas, by absorption with cold methanol as physical detergent, wherein the methanol is cooled in a compression refrigeration machine by using a multi-component coolant. The use of the coolant according to the invention provides significant advantages with regard to the compressor capacity required in the compression refrigeration machine for the provision of a defined cooling capacity.
