FIELD: separation; mixing.
SUBSTANCE: invention relates to a methanol synthesis unit comprising at least two methanol synthesis units located on a synthesis gas feed line, each having a cooling, separation, recuperative heating of synthesis gas and cooled catalytic reactor, as well as device for cooling and separation of waste gas, characterized by that as cooling devices, refluxers are installed in the separation and recuperative heating, and on the methanol output line from the device for cooling and separation of waste gas there is a device for methanol degassing, equipped with heat and mass exchange unit connected to catalytic feed line to device for cooling and separation of waste gas, as well as connected by degassing gas supply line with synthesis gas supply line to at least one of catalytic reactors.
EFFECT: use of the proposed apparatus increases output of methanol.
