Nitrogen machines and many air separation equipment production companies also have to comply with such shopping mall development rules. However, the terminal win is the base of the nitrogen machine company to win. Nitrogen-making machine company mall development is necessary to comply with the mall rules. From a scientific point of view, the development of shopping malls is not disorderly.

According to the study, 4% of new product launches fail because they choose the wrong shopping mall. Some companies play big and play small, regardless of their strength. Others act recklessly and look far beyond the immediate. After all, they develop shopping malls not from the company's shopping strategy, nor from the actual shopping mall, but to rush, hit where is where. Especially during the launch of new products, the company thinks that it can do shopping malls everywhere, which is really a mistake to know. When the mall is empty, selection becomes more important. At present, the domestic market mainly uses low and medium grade carbon molecular sieve, the annual total demand is more than 2000 tons, with the continuous development of China's economy, especially the continuous expansion of industrial planning, the level of demand for carbon molecular sieve will increase year by year. Especially in recent years, the state attaches great importance to the safety of coal mines, forcing coal mines to equip nitrogen machines, and further expanding the domestic demand for carbon molecular sieve.

Since 2000, the average annual growth rate has been more than 80 percent. Domestic market prospects are very bright. With the continuous sophistication of pressure swing adsorption skills, the use of nitrogen machines is more and more broad, the international need for carbon molecular sieve is also growing, the demand of developed countries such as Europe and the United States has steadily increased every year, in recent years, the demand of developing countries is changing with each new day, increasing at a doubling rate every year, preservation estimates, In 2009, the total demand of carbon molecular sieve in the world was more than 100 million tons.

According to the analysis of international and domestic professors, the carbon molecular sieve profession appears the following development trend: First, with the continuous expansion of the use of pressure swing adsorption nitrogen machine, the need for carbon molecular sieve continues to increase, which will further promote the development of the profession, in the next few years, this profession will become well-known from a rare profession. Secondly, with the progress of the depth of use, the need for nitrogen production, nitrogen recovery, pile density, compressive strength and other goals of carbon molecular sieve is getting higher and higher, and further improvement of commodity performance goals will be the general trend of this occupation in the future. Third, because carbon molecular sieve is the primary component of the pressure swing adsorption nitrogen machine, the cost accounts for more than 70% of the entire equipment, therefore, reducing the cost will be an important condition to promote the development of this profession. In the next period, companies will continue to explore the selection of new materials and new processes, and strive to reach the highest level with the lowest cost.

Nitrogen as a maintenance gas is extremely suitable, the first is its high cohesion energy, as long as the high temperature and high pressure (> 500°C, >100bar) or increase in energy, chemical reactions will occur, the current has grasped a nitrogen production field needs.
