Helium gas is one of the rare strategic materials indispensable to the development of national defense and high-tech industries. Helium - containing natural gas is still the only source of industrial helium production. China's helium resources are rather poor, low content, difficult to extract, high cost. Therefore, while protecting limited helium resources, it is of great significance to research and develop advanced helium extraction technology of natural gas for improving the economy of helium production, ensuring national helium safety and promoting the development of China's natural gas helium extraction industry.

Through the analysis and introduction of helium extraction technology, the cryogenic condensation method is more mature, but the energy consumption and cost are higher. Other helium extraction technologies such as adsorption method, absorption method and membrane permeation method have their own characteristics, but they cannot be applied in large-scale industry due to the limited application conditions. With the development of new materials and new technologies, the helium extraction technology from natural gas is constantly improved and innovated, the helium extraction processes such as adsorption method and membrane permeation method are developing rapidly, and the co-production method and joint process have a good application prospect. All these provide new ideas for promoting the development of the helium extraction technology from natural gas.

This product belongs to non-combustible gas hazard code: GB 2.2 Class 22007. UN NO. 1046; IMDG CODE page 2144, class 2.2. (compressed)GB 2.2 class 22008. UN NO. 1963; IMDG CODE 2144 page 2.2 class. (liquefied) Helium is an inert gas, and in high concentration it can reduce the partial pressure of oxygen and cause asphyxiation. When the concentration of helium in the air increased, patients first appeared breathing faster, attention deficit, ataxia; Fatigue, restlessness, nausea, vomiting, coma, convulsions, and death ensues. Liquid helium contact with skin can cause severe frostbite.
