What is an appropriate space velocity for the methanol synthesis tower? Space velocity concept: The volume of process gas passing through the synthesis tower per hour. For example, in a methanol synthesis tower with 72 cubic meters of catalyst, if the gas flow rate into the tower is 600,000 units per hour, the space velocity is 8,333. The required range for the catalyst is 5000–20000. It has little impact on devices with circulating gas, but it warrants consideration and research in the syngas system. It involves the question of whether to turn on the circulation pump.
The operation status of a certain bifunctional alcohol plant: the space velocity has a direct impact on the operation of the synthesis tower, and this image relates to the startup of the circulation pump.
Due to the low air velocity, the reaction heat cannot be removed in time, forcing the operation of a circulator. The airspeed was increased from 3300 to 5000.

Methanol synthesis is a systematic engineering task; it must not be considered based on a single variable!
With other parameters remaining unchanged, air velocity should still be given careful consideration.
