| titleOfInvention | Acetic acid production method |
| abstract | There is provided a method for producing acetic acid that can suppress sedimentation and accumulation of a catalyst in an evaporation tank, efficiently recycle the catalyst in a reaction tank, and thus contribute to maintaining and improving the productivity of acetic acid and ensuring stable operation. In the method for producing acetic acid of the present invention, the evaporation tank has a structure for preventing precipitation and accumulation of catalysts of at least one of the following (a) and (b). (a) A structure in which the inclination angle θ of the inner wall surface of the normal connection part of the evaporation tank is 5° to 85° (b) A vortex breaker having a plate-shaped vortex breaker main body and a leg supporting the vortex breaker main body horizontally. , The vortex breaker main body is arranged to cover just above the connection of the remaining liquid recycling line at the bottom of the evaporation tank, and the line speed r of the remaining liquid passing through the gap between the circumferential end of the vortex breaker main body and the inner bottom of the bottom of the evaporation tank is 10 m. Structure designed to be larger than /h |
