Abstract
A process for synthesis of methanol, where make-up syngas is reacted in a synthesis loop (10) obtaining crude methanol, and where a purge gas (20) taken from said synthesis loop is heated to 200-500° C. by indirect heat exchange with a high-temperature heat source, the heated purge gas (33) being expanded in a gas expander (34) to recover energy.
