C4 team of Yantai University helps Yulong petrochemical refining and chemical integration project

Recently, the C4 team of our institute and Shandong Haicheng Petrochemical Engineering Design Co., Ltd. (hereinafter referred to as”Haicheng petrochemical”, which is one of the collaborative units of our provincial Collaborative Innovation Center) jointly signed the”alkene separation unit technology license contract” with Shandong Yulong Petrochemical Co., Ltd. (hereinafter referred to as”Yulong petrochemical”) to be responsible for the process package preparation and engineering design of the 500000 T/a C4 separation unit of Yulong petrochemical. Yulong petrochemical refining and chemical integration project is a national key construction project in the 14th five year plan and a major project in Shandong Province, with a total investment of about 127.4 billion yuan. The first phase of the project mainly constructs 20 million T/a oil refining, 3 million T/a ethylene, 3 million T/a mixed xylene, gasoline, aviation kerosene, diesel, ethylene glycol, HDPE, UHMWPE, PP, EVA/LDPE, neoprene, integrated rubber and ABS and other deep-processing devices. This project is a part of it. The signing of the project will lay a solid foundation for the follow-up of phase I project and the further cooperation of phase II project.

Up to now, the C4 separation process technology of Yantai University has been transferred to 41 large chemical enterprises (48 units) in China, with an annual treatment of more than 8 million tons of C4, a cumulative patent license fee of more than 50 million yuan, a domestic market share of more than 95%, and has been highly recognized by petrochemical enterprises. According to experts’ demonstration, compared with foreign technologies, the C4 separation technology of Yantai University has the advantages of advanced process, simple process, low energy consumption, high product purity and yield, good solvent selectivity, no frequent regeneration of solvent and large flexibility of device operation. This technology won the national patent gold award independently in 2018. In the past three years, it has successively transferred four petrochemical enterprises including HSBC petrochemical. This time, the C4 team and Haicheng Petrochemical signed a cooperation agreement with Yulong petrochemical, which finally landed the technology in Yantai and helped Yulong Petrochemical develop at a high speed.

Over the past three years, the C4 team has achieved fruitful scientific research results, including 2 projects approved by the National Natural Science Foundation of China, 3 provincial and ministerial projects, and 5 department and bureau level projects. Among them, Professor Zhu Mingyuan and Professor Liu Jie have been respectively approved as youth and innovation team projects of Provincial Colleges and universities, Associate Professor Tian Hui has been approved as major scientific and technological innovation projects of the province, and the team has been approved as Yantai school land integration development platform projects. The total vertical funds are more than 8 million yuan, and more than 60 high-level scientific research papers have been published, More than 10 invention patents have been authorized, and 11 horizontal subject cooperation agreements have been signed with Yulong petrochemical, Harbin Petrochemical, Jingbo petrochemical, HSBC petrochemical and other enterprises, with a contract fund of about 7 million yuan.
