With the great improvement of traffic conditions, and the pursuit of a higher economic efficiency, liquid air products with good quality, lower transport costs, good cost performance and characteristics of safe and convenient, more and more get the favour of the user. Chinas vast territory, but the supply of industrial gas can be far from developed countries to covered hundreds of kilometers of the central gas supply scale, so the liquid sales became gas company is a good choice. At the same time, liquid products can better allocate the imbalance of supply and demand in each region. With the gradual normalization of the use of medical oxygen, the use of liquid oxygen to produce medical oxygen has become a trend. Therefore, in recent years, the demand of full liquid air separation equipment and liquefaction device is on the rise. ????? Kaifeng air separation group co., LTD., based on the existing liquefaction equipment, continuously makes technical improvements, and successfully produced all liquid oxygen and liquid nitrogen equipment at the same time in 1995. In 2000, two sets of air-separation equipment with this type of equipment, successfully exported Iran and passed the inspection and acceptance inspection. With full rectify and produce argon industrial application of the technology of kaifeng air separation group co., LTD and timely developed full rectification process of full liquid device, not only meet the needs of domestic users, and in 2000, export of Portugal in the form of sets of air separation equipment, the equipment in August 2001 final inspection acceptance by the user. All these indicate that our country has reached a new level in the development of air separation technology, and has the competitive ability to compete with internati
