I would like to ask about the functions and principles of the medium-pressure flash tower, reabsorption tower, thermal regeneration tower, and methanol-water separation tower in low-temperature methanol washing
There are too many issues to describe in detail
I’ll answer as much as I can; thank you!
The medium-pressure flash tower operates on the principle of pressure reduction to separate carbon monoxide and hydrogen from methanol, thereby recovering energy. The thermal regeneration tower removes hydrogen sulfide from methanol through heated distillation. The methanol-water separation tower is used to remove the water content of methanol from the purification system; the source of water in this system comes from the water separators and wash towers located before the shift gas tower and the unshifted gas tower.
