A method for the heat recovery from a reaction system for methanol synthesis is described, in which an outlet gas from a methanol synthesis reactor 102 is divided into two streams. One stream is subjected to heat exchange 103 with a starting synthetic gas 1,4 and the other stream is subjected to heat exchange 104 with part of a purge gas 5 which is separated in a separator 106 located downstream of the reactor 102. The two streams are combined and passed into the separator 106, and the heated purge gas 6 is passed into an expansion unit 108 to recover the heat of the purge gas. <IMAGE> |
