PRODUCTION OF ACETIC ACID WITH HIGH CONVERSION RATE

PRODUCTION OF ACETIC ACID WITH HIGH CONVERSION RATE

The present invention is to a process for producing acetic acid comprising the step of reacting a carbon monoxide feed and methanol and/or a methanol derivative in a first reactor to produce a crude acetic acid product. The carbon monoxide may comprise less than 99.5 mol % carbon monoxide. The proce...

description The present invention is to a process for producing acetic acid comprising the step of reacting a carbon monoxide feed and methanol and/or a methanol derivative in a first reactor to produce a crude acetic acid product. The carbon monoxide may comprise less than 99.5 mol % carbon monoxide. The process further comprises the step of purging a carbon monoxide purge stream comprising a first amount of residual carbon monoxide and one or more impurities. Preferably, the first amount is greater than 20 mol %. The process further comprises the step of separating the crude acetic acid product into at least one derivative stream comprising a second amount of residual carbon monoxide. The process further comprises the step of reacting at least a portion of the second amount of residual carbon monoxide and methanol and/or a methanol derivative in a second reactor to produce additional acetic acid.
