Improved mixing device for down-flow hydroprocessing reactor

An improved vortex-type mixing device for a down-flow hydroprocessing reactor is described. The device provides improved overall mixing efficiency of an existing mixing volume in the mixing of gas andliquid phases in two-phase systems while reducing the pressure drop through the device, as compared...

Beschreibung
Zusammenfassung:	An improved vortex-type mixing device for a down-flow hydroprocessing reactor is described. The device provides improved overall mixing efficiency of an existing mixing volume in the mixing of gas andliquid phases in two-phase systems while reducing the pressure drop through the device, as compared with prior art devices. Typical hydroprocessing applications include hydrotreating, hydrofinishing,hydrocracking and hydrodewaxing. 描述了用于向下流动式加氢操作反应器的改进的涡旋型混合装置。与现有技术装置相比，所述装置在混合两相体系的气相和液相方面提供已有的混合体积的改进的总体混合效率，同时降低穿过装置的压降。典型的加氢操作应用包括加氢处理、加氢精制、加氢裂化和加氢脱蜡。
