Abstract: Continuing from the preceding article, this article was based on an example of some shale oil finery plant. After the analysis and solving schemes on low oil yield rate with Fushun retort on shale oil production, the Fushun retort unit, heat supply system and oil-gas recovery system were analyzed and researched. The traditional shale oil production technology with Fushun retort was reformed collectively, and a new process technology was performed. The result proves that 80% to 85% of oil yield can be obtained with this new technology. If it is under regular operation and management, the production effect is expected to be better. Besides, the new process can increase productivity and autoimmunization degree. The better environmental protection goal, saving water source and reducing pollutants discharge can be realized. It overcomes the drawback of traditional process by technical innovation and upgrading. The superiority of handling low grade oil shale, rich operation and managerial experience can avoid a series of problems from old industrial enterprises, such as high investment, difficult operation and management through replacing retort unit and technology.

摘要：         以某矿业集团页岩炼油厂为例，继传统抚顺干馏炉低油产率分析之后，就抚顺炉装置、供热系统、油气回收系统三个方面加以研究分析，对传统的抚顺炉油页岩干馏工艺进行整体改造，设计出新的生产工艺流程。实践结果证明：改造后的生产工艺可以使油产率达到８０％～８５％，操作规范及管理得当可获得更好的生产效果。新工艺还可以使处理量增加、自动化程度得以提高，并实现了水资源节约、污染物减排的良好环境目标。此次技术改造和升级从根本上克服了传统工艺的弊端，可以处理低品位油页岩，避免了老工业企业彻底更换新型炉型带来的投资成本过大、操作运行管理难度增加等问题。
