Start Up Valve Switching On PSA Nitrogen Plant Automatically Controlled

Start-up valve switching on PSA nitrogen plant , automatically controlled by the controller

Working Principle Description:

PSA pressure swing adsorption nitrogen generator is an automatic equipment that uses carbon molecular sieve as adsorbent, uses the principle of pressurized adsorption and depressurization desorption to adsorb and release oxygen from the air, so as to separate nitrogen. Carbon molecular sieve is a kind of cylindrical granular adsorbent with micropores on the outside and inside, which is black. The pore size dispersion characteristics of carbon molecular sieve enable it to complete the kinetic separation of O2 and N2. Such pore size dispersion can make different gases disperse into the micropores of molecular sieve at different rates without crowding out any gas in the mixture (air).

The separation effect of carbon molecular sieve on O2 and N2 is based on the small difference in the kinetic diameter of the two gases. The kinetic diameter of O2 molecule is small, so there is a faster dispersion rate in the micropores of carbon molecular sieve, and the kinetic diameter of N2 molecule is large, so the dispersion rate is slow. The dispersion of water and CO2 in compressed air is similar to that of oxygen, while the dispersion of argon is slow. After all, the mixture of N2 and AR is enriched from the adsorption tower.

PSA nitrogen production uses the selective adsorption characteristics of carbon molecular sieve, and selects the cycle of pressurized adsorption and decompression desorption to replace the compressed air into the adsorption tower (which can also be completed by a single tower) to complete the air separation, so as to continuously produce high-purity product nitrogen.

Product Advantages:

• The start-up valve switching is automatically controlled by the controller, saving more labor force and investment.
• PSA nitrogen generator, which has automatic start-up valve switching, will be controlled by the controller.
• A million times of frequent switching of fault free special valves are adopted to ensure the stable operation of the system.
• The equipment of nitrogen generation system operates automatically, and the use process can be unattended.

Application fields:

Nitrogen, commonly referred to as inert gas, is used in some inert atmospheres for metal treatment and in bulbs to prevent arcing, but it is not chemically inert. It is an essential element in animal and plant life and an integral part of many useful compounds. Nitrogen combines with many metals to form hard nitrides, which can be used as wear-resistant metals. A small amount of nitrogen in steel will inhibit grain growth at high temperature and improve the strength of some steels. It can also be used to produce a hard surface on steel. Nitrogen can be used to produce ammonia, nitric acid, nitrate, cyanide, etc; In the manufacture of explosives; Filled high temperature thermometer, incandescent bulb; Form inert material to preserve the material and use it in a drying oven or glove bag. Liquid nitrogen during food freezing; As a coolant in the laboratory.
