| titleOfInvention | Method for producing acetic acid |
| abstract | In a scrubber system, separate and acquire methyl iodide and absorbing solvent efficiently, corrosion inside the distillation column does not easily occur, efficiently separate and recover hydrogen iodide and methyl iodide, or sufficient hydrogen iodide Provided is a method for producing acetic acid, which can be recovered. In the method for producing acetic acid of the present invention, the offgas is an alcohol having 2 or more carbon atoms, an ester of a carboxylic acid having 3 or more carbon atoms, an ester of a carboxylic acid and an alcohol having 2 or more carbon atoms, an ether, a ketone, water, or an alkaline aqueous solution. A first absorbing step of bringing the first absorbent into contact with a first absorbent containing carbon and absorbing the iodine compound in the offgas into the first absorbent, and the first gas containing alcohol having 2 or more carbon atoms and 3 carbon atoms. The above-mentioned carboxylic acid ester, ether, ester of carboxylic acid and alcohol having 2 or more carbon atoms, ketone, water, alkaline aqueous solution, or acetic acid is contacted with a second absorbent different from the first absorbent, and the first gas component A second absorption step of causing the second absorbent to absorb the iodine compound therein. |
