Two VPSA vacuum pressure swing adsorption oxygen production units at Zhongke Fuhai Anyang Iron and Steel have been successfully put into operation
Thread Content
Recently, two sets of 7500 Nm3/h VPSA vacuum pressure swing adsorption oxygen generation units supplied by Beijing Zhongke Fuhai Low-Temperature Technology Co., Ltd. (hereinafter referred to as Zhongke Fuhai) to Anyang Iron and Steel Group Co., Ltd. (hereinafter referred to as Anyang Iron and Steel) were successfully put into operation. From March 22 to 27, the two units operated simultaneously to supply gas to the blast furnaces (Unit 2 was completed for commissioning on February 21, and Unit 1 on March 5), delivering oxygen of qualified quality with output and purity both meeting the specified performance standards. The entire process of this device features safety and reliability, low energy consumption, small space requirements, a high degree of automation, and easy start-up and shutdown ； The scale of a single unit is one of the largest in the industry.
This project has a short timeline, high requirements, and a broad and complex scope. Zhongke Fuhai assigned a team with extensive experience in domestic and international EPC turnkey projects to successfully carry out the design, manufacturing, installation, commissioning, and delivery of the VPSA oxygen generation equipment. Throughout the project implementation process, Zhongke Fuhai remained committed to putting customer needs first. It overcame various challenges such as the once-in-a-century flood in Henan on July 20, the recurring impacts of the COVID-19 pandemic, and limitations in plant layout, staying on site to drive forward the project progress and providing strong support for the smooth commissioning of the customers’ technical upgrade projects. At present, the two VPSA oxygen production units operated by Zhongke Fuhai are functioning smoothly; all performance parameters of the output oxygen meet the design requirements. This improves the redundancy of oxygen supply for Anyang Iron and Steel, reduces the costs associated with oxygen production, and meets the oxygen supply needs required to increase steel production capacity. The successful commissioning of this project indicates that Zhongke Fuhai now possesses mature VPSA core processes and production technologies, as well as the capability to manufacture extremely large vertical radial-flow VPSA units with a capacity of up to 7500 Nm3/h. This lays a solid foundation for Zhongke Fuhai to build even larger air separation units in the future.
It is an honor to be involved in the on-site construction of this project as well as some of the construction work
I can share some characteristics of constructing devices of this type
The construction of such devices is primarily aimed at addressing the vibrations generated by moving equipment.
Vibration of moving equipment is a major issue that design institutes must take into full consideration
