More people’s participation makes things more lively; Haichuan becomes even better with you in it. This is just a tentative contribution – we welcome everyone to engage more actively in discussions on this forum. Replies will be rewarded; feel free to discuss! ------------------------------------------------- The oil residue hydrogen production unit in Zhejiang Petrochemical’s 40 million tons/year integrated refining and chemical processing project (Phase II) involves gasifying and converting the oil residues produced by the upstream units of this facility, so as to produce hydrogen-rich purified gas that can be used in pressure swing adsorption hydrogen purification systems. The hydrogen production from oil residue in Zhejiang Petrochemical’s 40 million tons per year integrated refining and chemical processing project (Phase II) utilizes Shell gasification. Dongfang Boiler manufactures Shell boilers. This is the first domestically manufactured Shell oil residue gasifier, and it is currently the gasifier with the highest parameters in the world. The gasifier burners are provided by the 711th Research Institute of China State Shipbuilding Corporation. In July 2021, the first set of burners for the gasification furnace in Zhejiang Petrochemical’s Phase II oil residue hydrogen production unit, supplied by CSIC Institute 711, was successfully ignited and put into operation at once, producing qualified hydrogen at a gasification furnace pressure of 6.5 MPa. The burner in the residue oil gasification process is an oil-gasification burner, and it represents the core equipment of the entire hydrogen production system from oil residues. It plays a crucial role in ensuring the efficient utilization of oil residues and reducing environmental pollution. In the design process, the project team at 711 Institute overcame numerous technical challenges, including the design of complex flow channel structures, the development of flame-stabilizing systems for ultra-high-speed burners, five-axis machining of high-hardness materials, deep drilling operations, and high-precision welding and assembly. As a result, they provided 9 seven-channel process burners and 3 auxiliary burners for the second-phase gasification furnace project at Zhejiang Petrochemical Company. The successful ignition and operation of the first set of burners in this project met the owner’s high-tech requirements for the localization of key burner equipment, thereby winning the owner’s trust. 711 Institute will continue to provide users of gasifier burners with products of better performance and more satisfactory service.
