Process for continuous acetic acid production

A process for producing acetic acid that involves operating the flash vessel and first column at the lowest possible pressure for a given production rate is described. Low pressures are achieved by operating on a back pressure established by a vapor discharge from an absorbing system. This reduces t...

Zusammenfassung:	A process for producing acetic acid that involves operating the flash vessel and first column at the lowest possible pressure for a given production rate is described. Low pressures are achieved by operating on a back pressure established by a vapor discharge from an absorbing system. This reduces the pressure differential to allow steady and efficient acetic acid production.
