AIR SEPARATION PLANT

   The large and medium-sized air separation plants are our main products. The ASP products designed and manufactured by our company have been in series with the maximum specification of 40,000m3/h. In the 1990s, the application of the new technologies such as the molecular-sieve pre-purification process with booster expander, the structured packing rectifying column and the argon-producing without hydrogen etc, has reached the world advanced level of the 1990s and takes leading position in China.
   The large and medium-sized air separation plants produced by our company include: 1000, 1500, 3200, 4500, 6000, 7500, 10000, 15000, 28000 and 40000 m3/h and high-purity nitrogen serial plants. In the 1990s, our company developed the international market and successively exported the 300 m3/h, 800 m3/h, 1500 m3/h, 3200A m3/h, 4500 m3/h, and 6000 m3/h and several sets of cryogenic liquid plants to the Indonesia, India, Philippines, Iran, Europe, Viet Nam, Turkish and Iraq etc.
   In the new century, our company increased the exploitation of the large-scaled ASP products with internal compression process, and supplied several sets of large ASP with internal compression process, the pressure grade of 2.5-8.5Mpa and capacity of 10,000~40,000 m3/h for the metallurgical and chemical industries, inside which the 40,000 m3/h-grade large ASP is the largest self-designed and manufacturing ASP in China.
   Our company can also design and manufacture ASP products as per the customers¡¯ requirements either to produce the liquid & gaseous oxygen, nitrogen and argon with one ASP or only produce single product such as the liquid or gaseous oxygen or nitrogen products with individual ASP.
