What is Pressure Swing Adsorption (PSA)? PSA technology, unlike hollow fiber membrane technology, utilizes a selective sieve material loaded into multiple adsorber beds. The sieve material is designed to selectively adsorb the waste gas while the desired gas is allowed to pass through the sieve material unaffected. The sieve material has a unique property that …
How to make anhydrous ethanol (100% alcohol)? Water and ethanol form what is known as an azeotrope. This occurs when a mixture of liquids has a higher or lower boiling point than each of the individual components. In the case of ethanol, a mixture of 95% ethanol to water boils at a lower temperature than …
https://youtu.be/jzQFpoSYBSg How does Desiccant dryer work for compressed air? A desiccant dryer uses chemicals called desiccants to remove moisture from compressed gas. Two commonly used desiccants are molecular sieve and activated alumina. This is a simplified illustration of one type of desiccant dryer. The desiccant is contained in two tanks. The dryer also has a …

Ambient air is, of course, all around us. But for patients with respiratory viruses like Corona Virus, medical-grade oxygen is essential. Ambient air contains 21 percent oxygen concentration. Medical grade oxygen can ramp that proportion up and is dispensed at a higher flow rate — helping patients efficiently oxygenate their bodies. Corona Virus can cause …
How to choose adsorbents for cracked gas dehydration? Molecular sieves are widely used to dry cracked gas and olefin cuts in gaseous or liquid phases. This process is critical, since fluids, after drying, are subjected to low temperature treatment. Any remaining water would cause freezing or the formation of hydrates. The immediate consequence would be …

BACKGROUND An air separation plant is separation atmospheric air into primary components, commonly nitrogen, oxygen and argon and sometime other gas such as xenom, carbon dioxide and more. The purpose air separation plant is to separate nitrogen from the air and use nitrogen in variety purpose. For example, Nitrogen usually used in purging before chemical …

How is molecular sieve produced? Molecular sieves as microscopic crystals in powder form before being moulded into exrudates and granules. Molecular sieve crystals are grown in special solutions at high temperatures. The solutions are prepared by loading a mixture of different components in a specific ratio into a crystallizer. Seeding the solution guarantees the crystals …
What is molecular sieve used for It is hard to imagine the production of oil and gas without the use of high quality products such as molecular sieve- those highly adsorbent and effective catalyst. Molecular sieve dehydrates air in truck braking systems, in control equipment systems, extract water from the Freon in air-conditioners and …
Open date: 22 Dec 2020 Deadline: 4 Jan 2021 Product name: Manganese dioxide; Manganese peroxide (MnO2) Purpose: Manganese peroxide (MnO2) is used in the production of zinc metal by the central plant of JSC “Almalyk MMC” Technical requirement: In accordance with YBT 5084-2015 MnO2 content not less than 72% Moisture content not more than 8% Sulfur …
How molecular sieve works? Synthetic zeolites are produces in the form of granular extrudates, which have different microcrystalline structures. The input window of the molecular lattice can vary in size from 2-15 angstroms depending on what chemical process the zeolites are intended for. But their main purpose is the dehydration, purification, and separation of gases …
What is molecular sieve? Molecular sieves are crystalline metal aluminosilicates having a three dimensional interconnecting network of silica and alumina tetrahedra. Natural water of hydration is removed from this network by heating to produce uniform cavities which selectively adsorb molecules of a specific size.A 2.5-5 mm (4 x 8-mesh) sieve is normally used in gas …
