Air Liquide Group entered China in 1916 and has accelerated its business development in the past decade. Currently, it has more than 70 factories in China, covering over 30 cities and employing approximately 4000 people. The main business scope of Air Liquide Group in China includes the operation of industrial and medical gases, as well as the engineering and manufacturing business carried out by its Engineering Technology Division (design, manufacture, and installation of air separation/hydrogen production units). The business of Air Liquide Group has been sold to important coastal industrial areas in China and continues to expand to the central, southern, and western regions.

In recent years, I have collaborated with Great Wall Technology Industry and Trade and Liquefied Air Group to explore the application of specialty gases in various industries. At present, in the process of cleaning automotive parts, we have jointly developed new products and laid them out on the production lines of car companies, reducing production costs, minimizing environmental pollution, and effectively improving efficiency.

Great Wall Technology Industry and Trade is a technology innovation enterprise that integrates research, development, manufacturing, and operation. It specializes in providing excellent equipment for scientific research and industrial applications in fields such as chemistry, biology, pharmaceuticals, electronics, petroleum, and new materials.
