Research and development of China's natural gas interchangeability identification software

In order to better judge the interchangeability of two different gases with different components and combustion characteristics, the paper analyses the method of foreign gas interchangeability and the characteristics of the domestic gas, and elaborates the identification method of theoretical research. According to the theory principle of these methods, such as Wobbe index, American gas association (A.G.A), Weaver, Delbaurg Law and Dutton, the program is complied. The features and functions of gas interchangeability identification software are introduced, which proves the importance of developing corresponding identification software. In addition, the graphical method is used to compile a logic diagram and gather all kinds of gas source, by which the identification method of natural gas interchangeability can be summarized. The practical application prospects of the software are also forecasted.
