Methanol is distilled in three towers; the pressurized reflux tank is alkaline
Thread Content
What other substances besides ammonia can make the pressurized scrubbing tank alkaline? Recently, the pressurized reflux tank has been showing an alkaline pH, and the cause cannot be identified
The pH value is normal, around 8 or 9.
Shouldn’t the pH inside a normal tower be maintained between 7 and 11?
Yes, the pH of the pre-tata reactor is normal, but the pressurized reflux tank is alkaline.
