Cracking C9 deep processing system and method thereof

According to the cracking C9 deep processing system and the cracking C9 deep processing method disclosed by the invention, a hydrofining process is adopted, aromatic components and olefin components in the cracking C9 deep processing system are saturated and then are directly blended into finished diesel oil, so that the total yield of the finished diesel oil of a company is obviously increased, and the economic benefit of hydrogenation C9 is greatly improved; according to physical and chemical properties and composition analysis of cracked C9, after full evaluation, the material is sent to a diesel oil hydrofining device, and more than 95% of diesel oil components can be obtained, which is far better than the processing benefits of the original process, so that the purpose of maximizing the benefits is achieved. 本发明公开的是一种裂解碳九深加工系统及其方法，采用加氢精制工艺，饱和其中的芳香组分和烯烃组分后直接调入成品柴油中，明显增加公司成品柴油的总收率，进而大幅提升了加氢碳九的经济效益，根据裂解碳九的物理、化学性质及其组成分析，经充分评估后，将该物料送至柴油加氢精制装置，可得到95％以上的柴油组分，远远好于原流程的加工效益，为了实现效益最大化的目标。
