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.
