Abstract: The present disclosure relates generally to processes for scrubbing an off-gas stream of an acetic acid production unit. In one aspect, a process includes introducing the off-gas stream to the absorption column; introducing to the absorption column, a methanol stream at a first flow rate, the methanol stream having a first temperature at the liquid inlet, the first temperature being at least 18° C. (e.g., at least 20° C., or at least 22° C.); in the absorption column, contacting the off-gas stream with the methanol stream; through a liquid outlet of the one or more liquid outlets, withdrawing a first liquid effluent from the absorption column, the first liquid effluent comprising methanol and methyl iodide; and through the vapour outlet, withdrawing a vapour effluent from the absorption column.

Abstract: The present disclosure relates generally to processes and systems for production of acetic acid. In one aspect, the disclosure provides a process for producing acetic acid that includes contacting carbon monoxide and one or more of methanol and reactive derivatives thereof with a carbonylation catalyst in a first reaction zone to produce a product stream, transferring at least a portion of the product stream into a second reaction zone; at a first position between the reaction zone inlet and an outlet of the second reaction zone, introducing a first vapour stream (90-100% CO) to the second reaction zone; at a second position between the reaction zone inlet and the outlet, introducing a second vapour stream the second vapour stream comprising less than 90 wt. % carbon monoxide; and through the outlet, withdrawing an effluent of the second reaction zone.
