Method for producing acetic acid |
| abstract |
The invention provides a method for producing acetic acid, which includes an absorption step: when there is a step of separating methyl iodide from the solution after absorbing methyl iodide, the step is energy-saving and the separation of methyl iodide can be performed efficiently.nThe production method of acetic acid of the present invention includes the following absorption step in the production process of acetic acid: at least a part of the outgas generated in the process is supplied to the absorption tower to contact with an absorbent containing an organic acid having a boiling point higher than acetic acid, The absorbent is allowed to absorb the iodine compound in the outgas and separated into a gas component having an iodine compound concentration lower than the outgas and a solution containing the absorbent and the iodine compound. |
