Nitrogen machine and a lot of air separation equipment production companies have to comply with the rules of the development of such shopping malls. However, the terminal is the base to win the nitrogen machine company to win. Nitrogen machine company shopping mall development is necessary to comply with the rules of the market. Starting from the scientific point of view, the development of shopping malls are not disorderly. According to the study, 4% of the reasons for the failure of the new commodity market, because the wrong choice of shopping malls. Some companies regardless of the strength, blindly play down. There are some companies rush away. After all, they are not shopping malls development from the company strategy is not to start from the mall but crashed off the truth, which is what. Especially in the new market, the company thought that everywhere can do shopping, which is a kind of know the fault. In the mall a blank, selection becomes particularly important. At present, low carbon molecular sieve in the domestic market first, total annual demand in more than 2000 tons, with Chinese economic development, especially industrial chemical industry planning continues to expand, on carbon molecular sieve level will increase year by year. Especially in recent years, the state attaches great importance to the safety of coal mines, forcing coal mine equipment nitrogen making machine, and further expand the domestic demand for carbon molecular sieve. According to the survey, since 2000, the average annual growth rate of more than 80%. Domestic market prospects are very broad. Along with the increasingly sophisticated skills of PSA, nitrogen use becomes more and more broad, the need for the international of carbon molecular sieve is also growing, demand every year in Europe and other developed countries has increased steadily in the past few years, the country is in need of change rapidly, annual increase exponentially, save estimates, the 2009 international carbon molecular sieve to the total volume of over one hundred million tons. According to the analysis of the domestic and international professors, carbon molecular sieve occupation following development trend: first, follow the use range of PSA nitrogen expansion, increasing the need for carbon molecular sieve, which will further promote the development of occupation, the next few years, the occupation from a lonely occupation become as everyone knows. Secondly, follow the use of the depth of the progress of carbon molecular sieve nitrogen yield and nitrogen recovery rate, bulk density, compressive strength and other targets need more and more high, further improve the commodity performance target will be the trend of the future development of occupation. Third, because the carbon molecular sieve is the primary component of PSA nitrogen making machine, accounting for more than 70% of the cost of the entire equipment, thus reducing costs will be an important condition to promote the development of the profession. After a period of time, the company will continue to explore the use of new materials and new technology, and strive to reach the highest level of the lowest cost. Nitrogen nitrogen nitrogen nitrogen gas as maintenance and maintenance for the extreme gas suitable, mainly is its high cohesive energy, as long as the high temperature under high pressure (> 500 C, >100bar) or increased energy, will attack the chemical reaction, currently holds a production of nitrogen gas needs.
