中文摘要：以中石化洛阳分公司 70 万 t/a 连续重整装置为例，介绍了大处理量下对采取先分馏后加氢预处理工艺的攻关优化。分析了洛阳石化连续重整装置实现常压石脑油直供后，大处理量下预处理单元出现的问题，结合车间的一系列优化措施，提出了解决问题的方案，通过优化，保证了重整进料品质，稳定了预处理操作，提高了经济效益。
英文摘要：Take the 700 kt /a continuous catalytic reforming unit of SINOPEC Luoyang Petrochemical Company as instance, the large capacity optimization operation for fractional distillation before hydrogenation process is introduced．The problems of pretreatment unit under the large handing capacity after atmospheric naphtha direct supply of reforming are analyzed. Combined with a series of optimization measures, the solution to solve the problem is proposed. Through optimization, reforming feed quality is guaranteed, preprocessing operation is stable and economic efficiency is improved.
