摘　　要：以柴油加氢精制装置的基本数据为计算基础,通过工艺计算,分析过剩氢、循环比、汽提氢等对采用连续液相加氢技术的柴油加氢精制装置操作的影响。结果表明:少量的气态过剩氢就能建立起较高的氢分压;循环油有助于控制催化剂床层温升;适量的汽提氢能有效稀释反应器内硫化氢的浓度。说明连续液相加氢技术可以实现滴流床技术中循环氢系统的作用,加氢装置今后有可能取消循环氢系统。Based on the operation data from gas oil gen, recycle liquid ratio and stripping hydrogen on the hydroprocessing technology are analyzed by simulative hydrotreating units, the impacts of excess hydrooperation of unit adopted continuous liquid-phase calculation. The calculation results show that a small amount of gaseous excess hydrogen in reactor can build up a relative high hydrogen partial pressure; the presence of recycle oil is helpful to reduce the rise of temperature along catalyst-bed; moreover, an appropriate amount of stripping hydrogen can dilute the H2S concentration in reactant significantly. Therefore, it is well founded that the functions of recycle hydrogen system in conventional hydrotreating unit are fulfilled by the continuous liquid-phase hydroprocessing technology, which indicates that the recycle hydrogen system in hydroprocessing unit might be canceled in future.
