| titleOfInvention | method to produce acetic acid |
| abstract | A method for the production of acetic acid, which suppresses precipitation and catalyst accumulation in an evaporator, can efficiently recycle catalysts to a reactor, and can contribute to maintaining and improving acetic acid productivity and ensuring safe operation. In the method, the evaporator has a catalyst accumulation and precipitation prevention structure: (a) structure where the angle of inclination ¿of the inner wall surface of an inverted cone cylindrical connecting portion is 5 ° to 85 °; and / or (b) structure where a vortex breaker comprising a plate-shaped vortex breaker main body, and a leg, are arranged such that the main body of the vortex breaker covers just above the connecting portion of a evaporator bottom to a recycle line of the waste liquid stream and the linear velocity r of the waste liquid stream passing through a gap between the main body of the vortex breaker and the bottom of the evaporator is greater than 10 m / H. |
