Principle and characteristics of nitrogen production by molecular sieve small air separation unit

Author: DEAR AST

Nitrogen is a colourless, odourless, non-toxic and non-flammable gas at room temperature and atmospheric pressure, which is chemically stable and hardly reacts with other substances. Nitrogen is often used as a protective gas in a wide range of industries.

There are several main methods of producing nitrogen. One of these is molecular sieve nitrogen in air (variable pressure adsorption), which is a method of separating nitrogen and oxygen using air as the raw material and carbon molecular sieves as the adsorbent, using the principle of variable pressure adsorption and the selective adsorption of oxygen and nitrogen by carbon molecular sieves, commonly known as PSA nitrogen production. This method is a new nitrogen production technology that was rapidly developed in the 1970s. Compared with the traditional nitrogen production method, it has the characteristics of simple process flow, high automation, fast gas production (15-30 minutes), low energy consumption, product purity can be adjusted in a wide range according to user needs, easy operation and maintenance, low operating costs, and strong adaptability of the device.

Therefore, it is quite competitive among small air separation nitrogen production equipment and is becoming more and more popular among medium and small-scale nitrogen users. PSA nitrogen production has become the preferred method for medium and small-scale nitrogen users.

For different requirements of products, Dear Air Separation has rich technology and experience in production and design, design and adapt to small air separation nitrogen production process.

Liquid air separation plant cold energy utilises air separation equipment, generally large air separation equipment with 2 combined expanders. The price is around 4 million RMB. The expansion air in the air separation plant is no longer required, so for the internal compression process air separation, the inlet air volume of the circulating booster is reduced by about 40% (from 5.A-2A). The energy consumption of the booster is reduced and the investment is reduced. Liquid air separation equipmen...
