Advancing CPL quality by hydraulic cyclone side test

This paper analyzed the main factors which influence the stability of the on-board distillation system inside the cyclohexanone ammoximation devices, as well as the quality of its intermediates, which is cyclohexanone oxime （CHO）. With the existing technology and equipments, a hydraulic cyclone side test of the toluene- Oxime mixture was carried out. The results showed that the quality of CPL could be greatly improved by the hydraulic cyclone purification technology.
