| titleOfInvention | Method for treating heavy residual liquid in ketoxime production |
| abstract | The invention relates to a method for treating residual liquid in a butanone oxime production process, which can recover a large amount of butanone oxime and obviously reduce the discharge of the residual liquid. Firstly, carrying out flash evaporation on butanone oxime residual liquid under a vacuum condition, and then regulating the ph of the flash evaporation residual liquid to be 3-6 so as to hydrolyze the butanone oxime in the residual liquid; then the residual liquid enters a residual liquid stripping tower and is stripped and flashed by steam; butanone/oxime/water at the top of the residual liquid stripping tower enters a separator and is stripped by waste water, and steam at the top of the waste water stripping tower is used for residual liquid stripping steam, so that energy is saved and consumption is reduced. And the heavy components after the flash evaporation residual liquid is stripped are sent to be burnt in the form of residues. The invention provides a method for treating residual liquid in a butanone oxime production process, which greatly reduces the production cost and reduces the discharge of the residual liquid. |
