The principle of industrial oxygen air separation plant is to separate oxygen and nitrogen from air by physical method. The purpose of industrial oxygen air separation plant is to produce oxygen for steel making. Oxygen and nitrogen are important metallurgical raw materials. The cost of industrial oxygen production is a point that many enterprises are concerned about. In addition, a large number of oxygen production is needed, but the requirements for purity are generally not very strict. The main method of industrial oxygen air separation plant is physical oxygen making. The preparation of oxygen from air is called air separation method by using the different boiling points of oxygen and nitrogen (the boiling point of oxygen is - 183 ℃, the boiling point of nitrogen is - 196 ℃).
