Process for producing acetic acid |
| abstract |
A process for stably producing high-purity acetic acid while efficiently removing acetaldehyde is provided. n The process for producing acetic acid comprises a reaction step for allowing methanol to react with carbon monoxide in the presence of a metal catalyst, a halide salt, and methyl iodide; a step for continuously feeding a flasher with the reaction mixture and separating a lower boiling point component (2A) containing acetic acid and methyl iodide and a higher boiling point component (2B) containing the metal catalyst and the halide salt; a step for feeding a distillation column with the lower boiling point component (2A), and separating a lower boiling point component (3A) containing methyl iodide and acetaldehyde and a stream (3B) containing acetic acid to collect acetic acid; a condensation step for condensing and temporarily holding the lower boiling point component (3A) in a decanter and discharging the lower boiling point component (3A) from the decanter; and a step for separating the lower boiling point component (3A) discharged from the decanter into acetaldehyde and a liquid residue and recycling the liquid residue to the reaction system. In the condensation step, the amount of the lower boiling point component (3A) to be held is controlled based on a fluctuating flow rate of the lower boiling point component (3A) to be fed to the decanter. |
