Regeneration Principle of Molecular Sieve in PSA Air Separation Plant For the PSA molecular sieve air separation plant, the molecular sieve is undoubtedly the core component of the system; only the clean compressed air is continuously adsorbed and regenerated through the molecular sieve, in order to continuously produce the nitrogen or oxygen we need. Regeneration can be understood as the reverse process of adsorption; because after the molecular sieve completes a saturated adsorption, it cannot continue to adsorb gas, and it needs to “recover” its adsorption capacity, which is what we call “regeneration”. Molecular sieve regeneration can help the molecular…

What Conditions Need to Be Controlled for the Production of Nitrogen Using Carbon Molecular Sieves? Carbon molecular sieve air compression purification process Purifying the raw air before entering the carbon molecular sieve adsorption tower is necessary because particles and organic atmosphere entering the adsorption tower can block the micropores of the carbon molecular sieve and gradually reduce its separation performance. There are methods to purify the raw air: 1) keeping the intake of the air compressor away from places with dust, oil mist, and organic atmosphere; 2) purifying the raw air with equipment such as a refrigerated dryer and adsorbent…

Composition of a Nitrogen Generator with PSA Molecular Sieve PSA molecular sieve nitrogen generator is mainly composed of the following parts: PSA molecular sieve compressed air purification components Composed of high-efficiency oil remover, refrigerated air dryer, precision filter and activated carbon filter. The working principle is that compressed air enters the air buffer tank for buffering, then enters the high-efficiency oil remover to remove most oil, water, dust and other impurities, then enters the refrigerated air dryer to remove more water, and finally enters the precision filter to remove oil and dust, and then enters the activated carbon filter for further…

How to Choose a High-performance Carbon Molecular Sieve Nitrogen Generation Equipment? Due to the different adsorption capacities of oxygen by carbon molecular sieve under different pressures and very significant differences, reducing the pressure can desorb the oxygen molecules adsorbed by the carbon molecular sieve, regenerate the carbon molecular sieve, and then repeat the cycle alternately to continuously produce high-quality nitrogen. The PSA nitrogen generator (pressure swing adsorption nitrogen production equipment) sold by manufacturers uses high-quality molecular sieves as adsorbents and directly obtains nitrogen from compressed air using the pressure swing adsorption principle. Complete process design, reasonable use effect. Reasonable internal components,…

The Role of PSA Molecular Sieve Nitrogen Generator in the Beer Industry With the increasing use of nitrogen, PSA molecular sieve nitrogen generators are becoming more and more widely used in various industries. For example, in the production process of beer, nitrogen also plays a role in gas protection. As the most widely used inert gas in nature, nitrogen is even more desirable than sterile compressed air for improving beer quality. This article will briefly introduce the wonderful effect of PSA molecular sieve nitrogen generators in beer production. PSA molecular sieve will not affect the taste and quality of beer…

How to Replace Carbon Molecular Sieve in Nitrogen Generator? When the nitrogen generator has been in use for a long time, the quality of the carbon molecular sieve will deteriorate and the purity of the produced nitrogen will decrease. Therefore, the carbon molecular sieve needs to be replaced to restore the purity. Many customers have reported that after the nitrogen generator has been used for a certain period of time, there will be a decrease in nitrogen production, a decrease in purity, and powder spraying, which requires a replacement of the carbon molecular sieve. The reasons why the carbon molecular…

Introduction to Carbon Molecular Sieve for PSA Nitrogen Generation With the wave of industrial revolution in the 1950s, the application of carbon materials became increasingly widespread, with the fastest expanding field being activated carbon, which gradually developed from filtering impurities to separating different components. At the same time, with advances in technology, human processing capabilities of matter became stronger, under which carbon molecular sieve was born. In the 1960s, carbon molecular sieves was successfully manufactured and quickly promoted in the United States. Initially, it was used as adsorbents to separate oxygen from air and gradually applied to devices for producing nitrogen.…

Instructions for the Use and Maintenance of PSA Nitrogen Generator Packing Carbon Molecular Sieve Nitrogen is the most abundant gas in the air, and it is an infinite source that can be used endlessly. It is colorless, odorless, transparent, and belongs to the category of weakly reactive gases, which cannot sustain life. High-purity nitrogen gas is often used as a protective gas to isolate oxygen or air. The content of nitrogen (N2) in air is 78.084% (the volume fraction of various gases in air is: N2:78.084%, O2:20.9476%, argon:0.9364%, CO2:0.0314%, and other rare gases such as H2, CH4, N2O, O3, SO2,…

Application of 4A Molecular Sieve Adsorbent in Gas-Liquid Drying Structure and performance parameters of 4A molecular sieve: 4A molecular sieve is an artificially synthesized zeolite, a crystal of silicate and aluminate, which is white in powder form. After adding a binder, it can be extruded into strips, flakes or balls. 4A molecular sieve is non-toxic, odorless, and non-corrosive. It is insoluble in water and organic solvents but soluble in strong acid and strong alkali. When heated, 4A molecular sieve loses its crystalline water, forming many small holes inside the crystal. The pore size is similar to the diameter of gas…

Advantages of PSA Molecular Sieve Pressure Swing Adsorption for Oxygen Production In industry, there are three main methods for oxygen production, namely cryogenic distillation, adsorption and electrolysis, and they all use different gas separation principles; cryogenic distillation is to first liquefy air at low temperature, and then separate oxygen and nitrogen by utilizing their different boiling points. Electrolysis is the process of putting direct current into water to separate oxygen and hydrogen. The Technical Characteristics of PSA Molecular Sieve The pressure swing adsorption method was launched in the late 1950s. It uses zeolite molecular sieves as adsorbents to adsorb and…
