| titleOfInvention | Method for producing acetic acid |
| abstract | Provided is a method for producing acetic acid which can suppress sedimentation and accumulation of a catalyst in an evaporation tank and efficiently recycle the catalyst in a reaction tank, thereby contributing to maintenance and improvement of acetic acid productivity and ensuring stable operation. In the method for producing acetic acid according to the present invention, the evaporation tank has at least one catalyst sedimentation and accumulation prevention structure of the following (a) and (b). (A) Structure in which the inclination angle θ of the inner wall surface of the inverted frustoconical cylindrical connecting portion of the evaporation tank is 5 ° to 85 ° (b) The plate-like vortex breaker body and the vortex breaker body are supported horizontally. A vortex breaker having a leg portion is disposed so that the vortex breaker body portion covers the residual liquid flow recycling line connecting portion at the bottom of the evaporation tank, and the peripheral end portion of the vortex breaker body portion and the evaporation tank. Structure designed so that the linear velocity r of the residual liquid flow passing through the gap between the bottom and the inner bottom surface is greater than 10 m / h. |
