Oxidation treatment of a recycle stream in production of acetic acid by methanol carbonylation

A method and system is provided for producing acetic acid by the catalytic carbonylation of methanol with carbon monoxide to obtain a reaction product stream comprising acetic acid and a minor amount of acetaldehyde. The acetaldehyde content in the reaction product stream is reduced by oxidation to...

description	A method and system is provided for producing acetic acid by the catalytic carbonylation of methanol with carbon monoxide to obtain a reaction product stream comprising acetic acid and a minor amount of acetaldehyde. The acetaldehyde content in the reaction product stream is reduced by oxidation to convert at least a portion of the acetaldehyde in the stream to acetic acid or further to CO2 and H2O. The oxidized stream may then be directed to the purification section, the reaction section, or both whereby the deleterious effects of acetaldehyde are reduced. Advantage of the present invention over conventional processes is the reduced need to dispose of acetaldehyde as waste and improved overall system efficiency in the production of acetic acid.
