DUN XIAN Single-Stage Isothermal Methanation Reactor Starts Up in Henan Yima

In 2022, the first single-stage isothermal methanation reactor developed by Nanjing Dunxian Chemical Technology Co., Ltd. was successfully started up in Henan Yima. This project represents a major breakthrough in methanation technology for synthesis gas applications.

Nanjing Dunxian Chemical Technology Co., Ltd. is a high-tech private enterprise founded by Mr. Wang Qingxin in 2009. The company is engaged in the research, development, and promotion of reactors and process packages for CO shift reactor, ammonia synthesis, methanation reactor, methanol reactor, and DME reactor. DUN XIAN holds nearly 30 patented technologies. Its Controllable Heat-Transfer Shift process and supporting water heat transfer isothermal reactors are patented and suitable for CO shift conditions. These technologies have been implemented in nearly 118 sets of operating units. The company holds a leading international position in this field, with a domestic market share of over 80% for isothermal shift technologies. DUN XIAN is also the only domestic supplier to provide shift technology and patented equipment to overseas companies such as Air Products (USA).

As the sole domestic supplier of patented equipment, the company participated in the national 13th Five-Year Plan key research and development project: New Technologies for Synthesis Gas (or Pyrolysis Gas) Methanation, and achieved a major breakthrough. Anhui Juyuan Machinery Equipment Co., Ltd., a wholly owned subsidiary of Nanjing Dunxian Chemical Technology Co., Ltd., holds pressure vessel design and manufacturing qualifications and is responsible for the fabrication of patented equipment developed by Dunxian Chemical and Dunxian Environmental.
