Optimisation Design and Application of Ball Valve for Ebullated-Bed Hydrogenation Unit
The main reasons that affect the long-term safe and effective operation of the ball valve in the ebullated-bed hydrogenation unit are jamming of the switch action,inadequate switch,and erosion of the flow channel between the ball and the valve seat.Based on the application conditions of the in service ball valve,fluid simulation analysis and comprehensive wear-resisting and erosion tests on the sealing surface,combined with theoretical analysis and finite element software,the optimization design of the ball valve is achieved.At the same time,the application situation of the valve is analyzed,and precautions for the installation and debugging of the ball valve are provided to better meet the working conditions and usage requirements.
