Air separation plant and principle

The environmental conditions considered by the air separation plant include: altitude, atmospheric pressure, ambient temperature, air humidity, the content of impurities such as carbon monoxide in the air, etc. These conditions vary with different regions and environments. Different environmental conditions have different effects on the performance of the same air separation plant. 1. Influence of atmospheric pressure on air separation plant: Atmospheric pressure is the pressure exerted on objects in the atmosphere by the gravity of the atmosphere itself. In general, the atmospheric pressure is about 0.1MPa. When the atmospheric pressure decreases, the compression ratio of the air compressor will increase, which will increase the energy consumption of the air separation plant. 2. Influence of ambient temperature and humidity on air separation plant: The increase of ambient temperature will reduce the air compressor's exhaust volume, increase the exhaust temperature, increas

A steel-making user of DEAR air separation set up their air separation plant in the early stage. At that time, due to the small amount of nitrogen required by the process and in order to reduce the investment, the molecular sieve adsorption purification process of 1:1 oxygen and nitrogen was adopted. There was no water chiller equipped, and a large amount of crude nitrogen was extracted to the water cooling column to reduce the temperature of cooling water.
