What is the relationship between fresh gas, process gas composition, catalyst temperature, and circulation volume in methanol synthesis?
A very comprehensive question, the process components are related to the fresh gas circulation gas and purge gas as well as the hydrogen added. The process gas composition and gas volume determine the intensity of production, and together with the catalyst activity determine the crude alcohol output. The circulation volume plus the fresh gas volume is the syngas volume, divided by the catalyst volume is the airspeed. The circulation volume is a measure of the system's ability to bring out products and heat. It is also a powerful means to adjust the hydrogen-to-carbon ratio of the syngas.
