摘　　要：中海油惠州石化有限公司二期项目2.6 Mt/a蜡油全液相加氢装置于2017年建成投产。该装置采用杜邦公司的IsoTherming全液相加氢技术设计,是国内首套采用全液相加氢技术的蜡油加氢装置。经过两年多的运转,该装置虽然经历多次开停工,但仍表现出较好的操作便利性和经济性。装置运行2年多后的标定结果表明:对于硫质量分数大于2.7%、氮质量分数大于500μg/g的沙特中质原油减压蜡油原料,加氢蜡油产品的硫质量分数小于1000μg/g、氮质量分数小于100μg/g,均满足催化裂化装置对进料的要求;装置标定期间的综合能耗为274.63 MJ/t,不但低于传统滴流床蜡油加氢装置,而且优于装置设计指标;装置整体运行情况达到设计要求。The 2.6 Mt/a gas oil full-liquid phase hydrogenation unit of the second phase of the CNOOC Huizhou Petrochemical Co.Ltd.project was completed and put into operation in 2017.The unit is the first gas oil hydrogenation unit adopting DuPont’s full-liquid hydrogenation technology in China.During 2 years operation,the device experienced many start-ups and shutdowns,but it still showed good operation convenience and economy.After more than two years of operation,the calibration results showed that for Saudi Arabia vacuum gas oil raw materials with sulfur mass fraction greater than 2.7%and nitrogen mass fraction greater than 500μg/g,the sulfur mass fraction and nitrogen mass fraction of hydrogenated gas oil products was less than 1000μg/g and 100μg/g,respectively,which could meet the feed requirements of catalytic cracking unit.The comprehensive energy consumption was 274.63 MJ/t,lower than those in traditional trickle-bed unit and superior to the device design.
