ABSTRACT:
An improved apparatus and method of producing acetic acid includes recovering product from the residue of a light ends column and feeding the acid so recovered forward in order to increase system productivity. Load on the light ends column is reduced and load on a dehydrating column may also be lessened in a preferred embodiment where the recovered acid is fed forward without further water removal.
