【摘要】：为满足1000×104t/a原油加工量,以及逐渐增长的航空煤油市场的需要,吉林石化公司需要新建一套航空煤油加氢精制装置,生产3#航空煤油,产量20×104t/a,供给长春龙嘉国际机场使用。新装置设计加工原料为俄油常一线和大庆原油常一线油按重量比45：55混合的,直馏宽馏分的混合原料。设计采用中石化的石油化工科学研究院(RIPP)研究开发的喷气燃料临氢脱硫醇RHSS技术精制直馏航煤馏分油生产3#航空煤油。为了降低加热炉操作条件的苛刻性,采用石科院开发的加氢精制催化剂和工艺技术,催化剂采用低温液相硫化,硫化剂是二硫化碳,催化剂的再生采用反应器内氮气循环再生法。设计采用先进的化工过程流程模拟软件对全流程进行模拟,确定合理操作参数,采用流路分析法进行换热流程优化。设计采用为双壳体的高压换热器；设计分馏塔采用高效的传质塔板,该类塔板的操作弹性大、板效率高,为日后装置的扩能奠定基础。确保装置设计的经济合理和操作可靠。装置建设从2013年4月开工,至2014年4月装置试车运行正常,产品合格,至2015年10月最大生产规模可达到29×104t/a。
[Abstract]:In order to meet the needs of 1000 脳 10 4 t / a crude oil processing and the growing aviation kerosene market, Jilin Petrochemical Company needs to build a new aviation kerosene hydrofining unit to produce aviation kerosene. The output is 20 脳 10 4 t / a for use at Changchun Longjia International Airport. The new equipment is designed and processed from a mixture of 45: 55 at the weight ratio between Rosneft crude oil and Daqing crude oil. Mixed feedstock of straight distillation wide distillate. Design and development of jet fuel hydromercaptan RHSS technology to produce aviation kerosene in order to reduce heating furnace. The harshness of the operating conditions, The hydrofining catalyst and technology developed by the Academy of Stones were used. The catalyst was cured by liquid phase at low temperature, and the curing agent was carbon disulfide. The catalyst was regenerated by nitrogen cycle regeneration method in the reactor. The whole process was simulated by the advanced chemical process simulation software, and the reasonable operation parameters were determined. The heat transfer process is optimized by flow path analysis. The high pressure heat exchanger with double shell is used in the design, and the high efficiency mass transfer tray is used in the fractionating column, which has the advantages of high operating elasticity and high plate efficiency. It lays a foundation for the expansion of the equipment in the future and ensures the design of the device is economical, reasonable and reliable in operation. The construction of the device started from April 2013 to April 2014, the test operation of the device was normal, and the product was qualified. By October 2015, the maximum production scale could reach 29 脳 10 4 t / a.
