Process for producing acetic acid |
| abstract |
The present invention relates to a carbonylation process for the production of acetic acid comprising separating a vapor product stream from a carbonylation reactor to produce a crude acid product comprising acetic acid comprising lithium cations, and combining the crude acetic acid product with acid A cation exchanger of the form is contacted in a first treatment unit to produce an intermediate acid product; and the intermediate acetic acid product is contacted with a metal-exchanged ion exchange resin having acid cation exchange sites in a second treatment unit to produce purified acetic acid. Specific embodiments are disclosed that relate to processing devices comprising a plurality of sampling ports having a first open flow path and a second flow path comprising a porous element. |
