Aldehyde removal process for methanol carbonylation |
| abstract |
Disclosed is a method for removing acetaldehyde and other permanganate reducing compounds (PRCs) from a process stream in the methanol carbonylation process for making acetic acid. The method includes the steps of forming an azeotrope to reduce the boiling point of the acetaldehyde and other PRCs to facilitate separation of the acetaldehyde and other PRCs from the process. In one embodiment the azeotrope comprises butane and acetaldehyde. |
