Does anyone know the process flow for three-effect distillation of methanol using five towers?
Thread Content
Currently, most systems use four-tower double-effect distillation; recently, a 600,000-ton capacity triple-effect five-tower methanol distillation plant is being developed, and PRO II simulation for the process is required
Five-column distillation, with thermal integration of the three product columns, and thermal integration of the recovery column and the pre-column. (The product towers control only the top of the tower; the methanol from the bottom of the atmospheric pressure tower enters the recovery tower.) In the middle are three product towers – pressurized, high-pressure, and atmospheric pressure – all of which require control only of the product at their tops
Fresh to this; I’ve never come across Five Towers before, and I hope to see more explanations
Ours uses four-column distillation; I haven’t worked with five-column systems yet. Could you tell me about them?
The coupling of heat involves the pressure tower driving the low-pressure tower and the atmospheric pressure tower, while the final tower drives the pre-tower. His sequence is pre-tower, atmospheric pressure tower, low pressure tower, pressurized tower, final tower, and washing and recovery tower. The next aspect concerns heat grading and hierarchical utilization; for more details, please visit the Xintianjin website.
With more equipment and increased investment, is it also easier to operate?
Tower 1: pre-treatment tower; Tower 2: pressure treatment tower; Tower 3: atmospheric pressure tower; Tower 4: recovery tower; Tower 5: washing tower, as well as the vent for the pre-treatment tower.

Which one works well? Which one has good design? Is there a lot more steam than in the Three Towers Province?
