| titleOfInvention | Method for producing acetic acid |
| abstract | The present invention provides a method for producing acetic acid, which can inhibit the precipitation and accumulation of catalyst in an evaporation tank, and efficiently recycle the catalyst to the reaction tank, thereby helping to maintain and improve the productivity of acetic acid and ensure stable operation.n n n In the method for producing acetic acid of the present invention, the evaporation tank has at least one of the following (a) and (b) structures to prevent catalyst precipitation and accumulation.n n n (a) Structure, in which the inclination angle θ of the inner wall surface of the inverted truncated cone cylindrical connection part of the evaporation tank is 5°~85°n n n (b) A structure in which a vortex crusher having a plate-shaped vortex crusher body and a leg that horizontally supports the body of the vortex crusher is arranged so that the body of the vortex crusher covers the residual liquid at the bottom of the evaporation tank Directly above the connecting part of the flow recirculation pipeline and designed to pass through the gap between the peripheral end of the vortex crusher body and the inner bottom surface of the bottom of the evaporation tank, the linear velocity r of the residual liquid flow is greater than 10m/h |
