Hydrogen Recovery from Methanol Plant Purge Gas

The synthesis gas is compressed and then reacted to form methanol. Unreacted syngas is recycled to the reactor. Since the normal ratio of hydrogen to carbon in the synthesis gas is greater than 2 ( the value required for methanol synthesis), excess hydrogen is removed by purging a hydrogen rich stream from the reactor loop and sending it to fuel.
