【Ten Years of Rapid Development in Chemical Processing Equipment】855-2023: The world’s first reactor feed vaporizer for styrene production units
Thread Content
The chemical engineering industry has seen significant development over the past decade; China’s prosperity and strength are truly admirable. By contributing our ideas, we can encourage more people to get involved and make the discussions more lively. HaiChuan becomes even better with your participation – we welcome everyone to join in the forum discussions more actively. ********************************************** Ranshi Heavy Equipment, thanks to its advanced manufacturing techniques and high-quality products, successfully completed the construction of two dehydrogenation reactors for the 600,000 tons per year styrene production facility at Sinopec’s Gulei petrochemical plant in 2020. These reactors performed well, earning high praise from the project owner, who awarded Ranshi Heavy Equipment the title of “Outstanding Supplier”. Two years later, as a strategic partner of Jingbo Holding Group, Ranshi Heavy Equipment took on the task of constructing two more dehydrogenation reactors and two reactor feed vaporizers for Jingbo Holding Group’s 600,000 tons per year styrene production facility in Shandong. The process technology used in these facilities is based on international standards; the reactors have larger diameters and higher capacity than before, requiring even stricter manufacturing standards. Among them, the feed vaporizer adopts entirely new chemical engineering technologies and structures, making it the world’s first such device.
The feed vaporizer was designed by the RANSI Heavy Equipment Repairs Research and Sales Center. State-of-the-art design methods used in the industry were applied throughout the process, ranging from process calculations and vibration analysis to structural optimization and strength design; finite element analysis was also conducted on the entire device. During the product development process, LANSI Heavy Equipment Qingdao Company exercised strict control over all stages, including preliminary preparation, scheme evaluation, testing, manufacturing, and inspection. Drawing on its experience in producing products for the Guli Petrochemical Project, it developed manufacturing techniques for rectangular tube boxes, inlet transition pipes, and large rectangular tube sheets. Through various experiments, it successfully developed techniques for corner welding of tube sheets to shells, full-position welding of tube boxes to tube sheets, as well as methods for overall heat treatment of irregular equipment inside furnaces, thereby ensuring product quality and timely manufacturing progress. On February 22, the completion acceptance meeting and shipment ceremony for the products of this project were held at LANSI Heavy Equipment Qingdao Company. Leaders from entities such as Jingbo Holding Group, Jingbo Petrochemical, China University of Petroleum (East China), and East China Design Institute, along with industry experts, attended the meeting to hear reports on the research, development, design, production, and manufacturing of the reactor feed vaporizer. After on-site inspections, discussions, and inquiries, the participants and experts unanimously agreed that the feed vaporizer for the 600,000 tons per year styrene plant (Badger process) developed by Lanshi Heavy Equipment for Shandong Zhongtai Chemical Technology Co., Ltd. meets the acceptance requirements and is ready for shipment.
