PSA gas separation technology in small air separation unit

PSA gas separation technology in small air separation unit
Jan 25, 2022
Author: DEAR AST

In recent years, pressure swing adsorption (PSA) gas separation technology has been widely used in petroleum, chemical, steel, metallurgy, electronics, medical and environmental protection fields due to its easy operation, room temperature operation, low energy consumption, high degree of automation and environmental friendliness. The core of the VPS device is the adsorbent, a significant feature of the adsorbent is that the adsorption capacity of different gas components is different under the same conditions, with selective adsorption; and the adsorption capacity increases as the adsorption pressure rises, and decreases as the adsorption pressure decreases, the adsorption pressure gradually desorbs the material adsorbed at higher pressure. It is this characteristic of adsorbents that is used in VPS small air separation units to achieve gas separation and continuous production.

 

Dear Air Separation cooperates with the world's top institutions to jointly research and develop the VPS gas separation technology, and has established joint laboratories with CAS, XPTC and XJTU, as well as a provincial engineering technology research centre, and has been awarded the national "small giant" enterprise.

At present, there are two types of common condensing evaporators in domestic air separation units, plate fin condensing evaporator and tubular condensing evaporator. Tubular condensing evaporator is divided into three types: long tube, short tube and coil. The long tube and short tube are all in row. The tube is made of red copper and the tube sheet is made of brass. It is generally used in small and medium-sized air separation plants. Coil type is generally used for auxiliary condensing evaporator. Because there is no fixed liquid level in the coil, the heat transfer coefficient is small, so it has been gradually eliminated. The plate fin condenser evaporator is made of all aluminum structure, and the plate unit is arranged in vertical star shape. Its characteristics are compact structure, light weight, small volume and easy to manufacture. It is widely used in large and medium air separation plants. Due to the gradual enlargement of the air separation unit, the heat excha
