Characteristics of Molecular Sieve Used in PSA Oxygen Production Systems The molecular sieve powder used in the PSA oxygen production system is an artificially synthesized crystalline aluminosilicate. Understanding of PSA molecular sieve PSA molecular sieve is used in the oxygen generation process of air separation and oxygen/nitrogen separation. Compared with ordinary calcium-type and sodium-type oxygen production molecular sieves, pressure swing adsorption is suitable for various VPSA devices and has better processing capacity and separation efficiency. In fact, there are not only one type of molecular sieve, and there are many types. At present, the main types commonly used are three…

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…

How to Determine the Adsorption Capacity of Activated Alumina? Activated alumina has applications in many fields, it can be used as adsorbent, desiccant and so on. These are inseparable from its appearance. Its molecular spacing and pore structure also make it a performance factor, so what does it look like? What about the adsorption capacity? Let’s take a look. Adsorption properties of activated alumina Activated alumina balls are prepared by high temperature dehydration at 400-600 degrees. Activated alumina is actually formed by agglomerating several orders of magnitude smaller particles, and the particles are aggregates formed by the coalescence of smaller…

4A Molecular Sieve Can Adsorb Low Molecular Weight Compounds 4A Molecular Sieve can adsorb small molecules such as water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene, etc., and does not adsorb any molecule with a diameter greater than 4A (including propane). It has high selective adsorption performance for water than any other molecule. 4A molecular sieve is one of the commonly used molecular sieve varieties in the industry Molecular sieve type 4A can evaporate water in a large space at 110℃, but it is impossible to remove the water in the pores. Therefore, in the laboratory, dehydration…

How to Achieve a Smooth and Reflective Surface on Ceramic Grinding Balls? Ceramic grinding balls have a shiny surface, some even reflecting light, what is the small secret behind this? In fact, the main factor that determines whether the surface of the ceramic grinding ball has a shiny effect is the flatness of the ball surface; the smoother the ball surface, the better the mirror effect; the rougher the ball surface is, the worse the mirror effect. The factors that affect the flatness of the ball surface mainly include: the internal structure of the material and the degree of external…
