Recovery tower
Thread Content
In the liquid-phase oxidation process for producing o-*formic acid* using o-xylene, what is the purpose of the recovery tower located after the oxidation reactor?
A recovery tower is a device used to treat and recover the waste gas generated in the reactor. In the process of producing o-*formic acid via the liquid-phase oxidation of o-xylene, the waste gas contains unreacted organic compounds as well as other impurities. A recovery tower can be used to condense, adsorb, and absorb these waste gases, thereby enabling the recovery and reuse of useful substances while reducing environmental pollution. Therefore, the recovery tower plays a role in purifying waste gases and saving resources throughout the entire production process. .
