【Ten Years of Rapid Development in Chemical Equipment】Major breakthroughs in gasification technology from 2018 to 2025! Commissioning of the heavy oil and gas hydrogen production unit in Zhenhai Phase II
Thread Content
Give praise and support to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Great Development in Chemical Engineering Equipment】Regular updates and summaries are available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** At 11:28 on January 5th, the heavy oil and gas-to-hydrogen production facility in the Zhenhai plant, for which Ningbo Engineering Company was responsible for preparing the process specifications, carrying out the engineering design, and providing EPC services, was successfully commissioned after its first attempt! At 9:18 on January 6, qualified hydrogen was successfully produced and connected to the power grid; the entire process took 22 hours. This facility became the first unit in the second phase of the Zhenhai base to achieve successful operation and produce qualified products, marking the large-scale industrial application of Sinopec’s proprietary heavy oil high-efficiency gasification technology. It represents another significant breakthrough in the SE series of gasification technologies, following the industrial application of technologies such as SE Eastern furnace powder coal gasification and SE water-coal (coke) slurry gasification. The heavy oil and gas-to-hydrogen production unit in Phase II of the Zhenhai facility utilizes process technologies owned by Sinopec, such as the SE heavy oil and gas conversion technology (one of the group company’s “Ten Dragon” scientific research projects), S-COS sulfur-tolerant shift technology, and S-AGR acidic gas removal technology. The SE heavy oil and gas conversion technology enables an effective gas production capacity of around 150,000 standard cubic meters per hour per reactor, making it the largest-scale heavy oil and gas conversion unit of its kind to date. It effectively addresses the challenges related to the efficient utilization of carbon-containing resources such as deoiled asphalt from refineries and unconverted oil from hydrogenation processes, as well as the treatment of high-concentration COD wastewater and liquid waste. Not only does it facilitate the efficient recycling of waste materials, but it also ensures the supply of hydrogen, syngas, and ammonia throughout the plant, serving as a key technology for creating “green enterprises” and “waste-free factories”. To support Zhenhai Refining & Chemical in ensuring smooth operation, the company established an expert technical support team composed of over 20 hydrogen production experts and key professionals, who worked closely with the project owner to carry out all the technical preparations during the water transportation and commissioning phases. By drawing on past successful startup experiences of gasification units, it provides proactive warnings about the common challenges that may arise during the startup of heavy oil gasification hydrogen production units, and formulates the best solutions. During the commissioning phase, especially when starting up the heavy oil gas-to-hydrogen production unit and diverting syngas to the purification unit, all members of the technical support team remained on site until qualified hydrogen was produced.

The SE gasification technology developed by Ningbo Engineering Company has formed a series.
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 transformation 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 transformation 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, combined with rich experience in engineering scaling and implementation, this technology optimizes the \"jet + plug flow\" flow field of the gasifier by adjusting its structure, along with the development of multi-channel burners and 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 time, and improved carbon conversion rates as well as effective gas composition ； 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 coking slag. Currently, Ningbo Engineering Company, Ningbo 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.
