High Degree Of Automation Can Realise Unmanned Operation For PSA Nitrogen Plant High Degree Automation

With features of simple operation and high degree of automation , unmanned operation of PSA nitrogen plant can be realized

Working Principle Description:

The compressed air enters the activated carbon filter through the air storage buffer tank to remove oil and water, then passes through the dry cooling and pressure relief of the cold dryer, and then enters the two adsorption towers after T-level and A-level precision filtration. PSA nitrogen production process is to select pressure swing adsorption (PSA) at room temperature as the adsorption separation process without heat source. The adsorption capacity of carbon molecular sieve for adsorption combination (mainly oxygen molecules) is added due to the increase of its partial pressure and reduced due to the decrease of its partial pressure.

In this way, the carbon molecular sieve is adsorbed under pressure and desorbed under reduced pressure to release the adsorbed part, so as to regenerate the carbon molecules and form a circular operation. In the PSA process, the cyclic operation includes several operation stages: adsorption, pressure equalization, depressurization, release, scouring, and then pressurization and adsorption, forming the cyclic operation process.

Product Advantages:

• The PSA nitrogen generator with simple operation and high degree of automation can realize unmanned operation.
• With features of simple operation and high degree of automation of PSA nitrogen generator, unmanned operation of the plant can be realized.
• Siemens PLC controls fully automatic operation, which can realize unattended operation and remote control of PSA nitrogen generator.
• The Siemens program controller of PSA nitrogen generator is adopted to realize the automatic control of the valve and 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.
