【Ten Years of Great Progress in Chemical Engineering Technology】Development of SE Water-Coal (Coke) Slurry Gasification Complete Sets of Technology and Industrial Application Evaluation from 2008 to 2023
Thread Content
Ten years of rapid development in chemical technology; praise for the prosperous and strong China. This is just a starting point to encourage more participation from everyone. HaiChuan becomes even better with your involvement – we welcome all to join in the forum discussions. Everyone should pay attention to safety and know how to handle emergencies. ********************************************* On April 22, 2019, the third gasifier in Zhenhai Refining & Chemical’s POX unit was successfully fed material for the first time, marking the complete commissioning of this unit using Sinopec’s own SE water-coal (coke) slurry gasification technology. “The “Development of a Complete Set of Technologies for SE Water-Coal (Coke) Slurry Gasification” project is one of Sinopec’s ‘Ten Dragon’ scientific and technological research projects. It was jointly developed by Ningbo Engineering Company, East China University of Science and Technology, and Zhenhai Refining & Chemical Co., Ltd., and was first applied industrially in the POX project at Zhenhai Refining & Chemical Co., Ltd. Since the successful commissioning of Gasifier No. 1 at the beginning of this year, through the scientific organization and diligent efforts of the project team, Gasifiers No. 2 and No. 3 were also successfully commissioned on their first attempt. On April 24, 2019, the Science and Technology Department of Sinopec Group sent a congratulatory message to mark the successful first trial run of the \"SE Water-Coal (Coke) Slurry Gasification Complete Set Technology Development\" project. The congratulatory message stated that as one of the group company’s \"Ten Dragon\" technology development projects, the Zhenhai Refining & Chemicals POX project achieved the goals of safety, environmental protection, and a successful first-time operation. This marks another significant achievement by Sinopec in the field of coal gasification technology. The message also encouraged the research team to continue leveraging the advantages of the group structure, to work together closely and strive hard to make further contributions to the advancement of coal chemical technology at Sinopec.
The development project for a complete set of technologies for the gasification of SE water-coal (coke) slurry was included in Sinopec’s \"Ten Dragon\" science and technology research projects in 2015. It was demonstrated through the restructuring and renovation project of hydrogen production raw materials at Zhenhai Refining & Chemical Co., with participating organizations including Zhenhai Refining & Chemical Co., Ningbo Engineering Company, Ningbo Institute of Technology, and East China University of Science and Technology. The hydrogen production raw material structure adjustment and renovation project at Zhenhai Refining & Chemical Co., Ltd. is a key project during the company’s 13th Five-Year Plan period, and it represents the first industrial application of the SE water-coal (coke) slurry gasification technology. Its core unit, the POX unit, uses water-coal (coke) slurry as raw material and can produce 100,000 cubic meters of hydrogen per hour; once operational, it will further enhance the company’s capacity for producing clean petroleum products. On January 31 of this year, the gasifier of the POX plant was started for its first feed operation; it took only 13 hours to complete the entire process, resulting in the successful production of qualified hydrogen product. Thereafter, through the scientific organization of the project team, Reactors 2 and 3 also achieved successful commissioning on their first attempts. According to a responsible official from the Ningbo Institute of Technology, the complete set of technologies for SE water-coal (coke) slurry gasification was jointly developed by Sinopec and East China University of Science and Technology. Based on extensive experimental data and scientific theoretical analyses, along with rich experience in engineering scaling and implementation, this technology optimizes the \"jet + plug flow\" flow field of the gasifier by adjusting its structure and developing multi-channel burners as well as a dual-feed system for coal slurry. This results in reduced short-circuiting of reaction particles within the enhanced plug flow field, a more reasonable distribution of residence times, and improved carbon conversion rates as well as the composition of the useful gases ； Keeping the flame away from the cone helps extend the lifespan of the refractory bricks at the bottom. The SE water-coal (coke) slurry gasification technology not only holds great prospects for the utilization of low-reactivity feedstocks such as petroleum coke, but its unique dual-path coal slurry feeding scheme also provides a new solution for the harmless treatment of organic wastes with poor slurry-forming properties, such as oil sludge and cokereast. Currently, Ningbo Engineering Company, Ningbo Research Institute of Technology, and East China University of Science and Technology are working together to develop a technology package for 2000-ton-class SE water-coal (coke) slurry gasification, as well as the core equipment required for such gasification – namely the gasifier system. Completion is expected by the end of this year, thereby laying the foundation for the larger-scale industrial application of this technology.
