Acetic acid recovery method |
| abstract |
(57) [Problem] To recover acetic acid from an acetic acid solution by a distillation method, not only to monitor the quality by continuously measuring the purity of the recovered acetic acid, but also to perform a purification operation such as a reflux ratio control. Is provided. SOLUTION: When recovering acetic acid from a solution containing acetic acid by a distillation operation, the conductivity of the recovered acetic acid is continuously measured, and the reflux ratio or the amount of heating is controlled according to the value. |
