渣油加氢装置反应温度操作初探

PRELIMILARY EXPLORATION ON HANDLING REACTION TEMPERATURE OF RESIDUE HYDROTREATING UNIT

介绍渣油加氢处理装置在催化剂床层平均反应温度相同时,各催化剂床层反应温度的不同组合对产品质量和装置运转周期的影响。试验结果表明,在渣油加氢催化剂的级配装填系统中,催化剂床层平均反应温度相同时各催化剂床层反应温度的不同组合对加氢常压渣油产品性质影响较小。为了保持加氢装置的长周期运转,各催化剂床层反应温度不应随意调整,脱金属催化剂的反应温度应有一低限值。

At same average reaction temperature of catalyst beds in residue hydrotreating unit, the effect of different combination of catalyst bed temperatures on product quality and running cycle was investigated. The result showed that its effect on product quality was small. For maintaining a long running cycle, the reaction temperature of each catalyst bed should not be adjusted voluntarily and the reaction temperature of the hydro-demetallization catalyst bed should be kept at a low limit.
