Why does a low CO content in the analysis of synthetic system gas result in less steam in the synthesis drum? Thank you.
With less steam, less gas is produced, because steam serves as a reactant; when its supply is reduced, less gas is generated
The drum steam is the by-product steam from the methanol reaction; in normal coal chemical processes for methanol production, there is a specific relationship between the amount of by-product steam generated and the amount of methanol produced, typically 1.0–1.3 tons of steam per ton of methanol. With a low CO content, the methanol production is low, and consequently the steam production is also low.
The methanol synthesis reaction is an exothermic reaction; the more methanol is produced, the more heat is generated, and consequently more steam is produced. With a small amount of CO, the methanol production naturally decreases.
With less reaction heat, less steam will be produced.
