摘要
介绍了中国石油天然气股份有限公司大庆石化分公司加氢裂化装置概况及生产状况,分析了装置生产喷气燃料的可行性,把装置生产的煤油分别与3号喷气燃料的国标及公司要求指标对比,发现适当调整煤油馏分的密度、冰点、润滑性及安定性指标就可使其成为合格的喷气燃料。归纳了影响装置产品质量的因素,由大到小依次为:操作条件、原料及产品、添加剂及设备因素。提出一系列的措施:控制好操作条件、稳定原料、改进工艺流程、加入添加剂、加强员工培训及细化管理等,其中严格控制好反应岗位、分馏岗位及制氢岗位的操作条件及平稳操作对生产合格喷气燃料尤为重要。装置生产的喷气燃料已通过了国家认证。
The conditions and production of the hydrocracking unit in the refinery of Daqing Petrochemical Company are introduced, and its feasibility of producing jet fuel is analyzed. The comparison with the requirements of national standard and specifications of Daqing Petrochemical Company for 3# Jet fuel shows that, the present kerosene fractions produced can be used as jet fuel when the density, freezing point, lubricity and stability of kerosene are well adjusted. The factors affecting product quality are given and the order of chief factors influencing jet fuel quality from high to low is listed, i.e. operating conditions, feedstock ＆ products, additive and equipment. A series of relevant countermeasures and solutions are presented such as good control of operating conditions, stabling feedstock, improving process, adding additives, strengthening technical training and detailing management. Three major sections of reaction, fractionation and hydrogen production must have a strict control of operating conditions to maintain a stable operation of the unit which is very important for the production of on-spec jet fuels. The jet fuel produced by the hydrocracking unit meets national standards, and the economic benefit is improved.
