Nitrogen is the main component of air, accounting for about 78% of the air. With the progress of science and technology and economic development, the application scope of nitrogen is expanding day by day and has penetrated into many industrial sectors and daily life fields.
There are several main methods for producing nitrogen gas. One of them is cryogenic air separation for nitrogen production, which is a traditional nitrogen production method with a history of nearly several decades. It uses air as the raw material, undergoes compression, purification, and then uses heat exchange to liquefy the air into liquid air. Liquid air is mainly a mixture of liquid oxygen and liquid nitrogen. By utilizing the different boiling points of liquid oxygen and liquid nitrogen (at 1 atmospheric pressure, the former has a boiling point of -183 ℃, while the latter has a boiling point of -196 ℃), they are separated through distillation of liquid air to obtain nitrogen gas. The characteristics of deep cold air separation nitrogen production equipment are high gas production, high product nitrogen purity, and can be stored in liquid nitrogen storage tanks, making it suitable for large-scale industrial nitrogen production.
Due to the irreplaceable competitive advantage of low-temperature separation method in large-scale molding of oxygen and nitrogen liquid products, especially high-purity products, and the fact that only low-temperature separation method has the ability to simultaneously produce rare gas products such as argon, low-temperature separation method occupies a very important position in the industrial application of air separation.
DEAR Air Separation has the technology and experience of cryogenic nitrogen production. Capable of meeting customer nitrogen production needs.
