The Zhongke Fuhai Huagan Ruilin VPSA oxygen production unit was successfully put into operation
Thread Content
Recently, a 6,000 Nm3/h VPSA vacuum pressure swing adsorption oxygen generation unit supplied by Jiangxi Zhongke Fulun Gas Co., Ltd. (hereinafter referred to as “Zhongke Fulun”), a subsidiary of Zhongke Fuhai, to Jiangxi Huagan Ruilin Rare Metal Technology Co., Ltd. (hereinafter referred to as Huagan Ruilin), was successfully put into operation. On April 14, the unit began operating and delivering gas to the grid (the machine integration test was completed on March 30), supplying qualified oxygen to the blast furnace. According to the design, the capacity of the unit is 6000 Nm3/h, with an oxygen purity of 90%. Based on the actual test results provided by users, the device generates an oxygen output of 6400 Nm3/h during operation, with an oxygen purity of 92%. All these parameters exceed the design specifications; the unit operates smoothly and effectively meets the oxygen supply requirements of Huagan Ruilin.
The entire process of this project involves purely physical changes; it operates under low or normal pressure, and there are no chemical synthesis or decomposition processes involved. As a result, the safety risks are low. It boasts advantages such as safety and reliability, low costs for oxygen production, low energy consumption during equipment operation, small space requirements, a high degree of automation, and easy start-up and shutdown. The VPSA oxygen production unit employs a radial adsorption tower design, which ensures a low linear flow velocity of air within the adsorption layer, optimal mass transfer, low resistance, and thus effective reduction in energy consumption losses ； The mass transfer zone is stable and controllable, which greatly reduces the abrasive wear of the adsorbent caused by air ； After debugging and compacting, no further replenishment is required during continuous production. The entire system features mature technology, high efficiency, and safety. This project has a short timeline, high requirements, and a wide and complex scope. Zhongke Fuhai provides one-stop EPC services, successfully completing the overall design, manufacturing, installation, commissioning, and delivery of VPSA oxygen generation equipment. Throughout the implementation process, the project team remained focused on meeting customer needs, overcoming various challenges such as local COVID-19 restrictions, poor transportation conditions, and insufficient on-site facilities. Through measures like on-site personnel coordination, remote communication, and video guidance, they made every effort to advance the construction and commissioning of the project, thereby ensuring its smooth operation.
The Huagan Ruilin rare and precious metals comprehensive recycling project, part of this collaboration, is one of the key provincial projects in Jiangxi Province. The successful commissioning of this project lays a solid foundation for ensuring a stable supply of gases to the Circular Economy Industrial Park in Fengcheng, Jiangxi, and contributes to the green development of the non-ferrous metal recycling industry. The commissioning of this project represents another application of Zhongke Fuhai’s technology in the field of oxygen-enriched combustion. This technology offers advantages such as high efficiency and low energy consumption, with the overall energy consumption being more than 15% lower than the industry average. As a practitioner in the development of green energy, Zhongke Fuhai is able to provide comprehensive solutions for China’s green gas and clean energy industries by developing key technologies and equipment with independent intellectual property rights. In the field of industrial gases, it is necessary to break the industry monopolies held by international companies, thereby promoting innovative development in related industries such as metal smelting, glass melting, and advanced manufacturing in China, with the goal of making greater contributions to the development of China’s gas industry.
