High Purity 8×12 2.0mm 3A Molecular Sieve Desiccant

High Purity 8×12 2.0mm 3A Molecular Sieve Desiccant

Product description

3A 8×12 Molecular Sieve is a multiple purpose, highly porous, high capacity alkali metal alumino-silicate in the spherical form. It is the potassium form of the Type A crystal structure with pore diameters of approximately 3Å. The 3Å pore opening will allow moisture to be adsorbed but will exclude unsaturated hydrocarbons and highly polar alcohols such as methanol and ethanol. It has high mass transfer efficiency and durability.

Product Features

• More efficient than older silica gel and alumina desiccants
• Crystalline composition
• Particularly useful in cryogenic operations
• Ease of use
• 1.5% wt. Water content (as shipped)

CHEMICAL FORMULA K12 [(Al02)12(SiO2)12] · nH2O

Regeneration

Removal of water: dry gas such as nitrogen, air, hydrogen, saturated hydrocarbon, etc. can be used to heat to 150-320℃ and pass into the molecular sieve bed under 0.3-0.5kg/m2 pressure for 3-4 hours, and then to the adsorber Pass in dry cold air for about 2-3 hours, isolate the air and cool to room temperature.

Removal of organic matter: the adsorbate can be replaced from the molecular sieve with water vapor, and then heated to (1). The regeneration can also be regenerated by superheated steam or inert gas at 200-350℃. Exposure to gases that produce explosive mixtures).

The degassed substances can be regenerated by the decompression removal method.

Package

Packed in iron drums, (according to the product model) net weight 125kg, 135kg, 140kg, or according to user needs.

Company information

Shanghai Xuefeng Molecular Sieve Co., Ltd. is a professional manufacturer of molecular sieve products, which belongs to Zhengzhou Xueshan Industrial Co., Ltd. Located in Shanghai Xinzhuang Industrial Zone, covering an area of 24 acer, it has nearly 7000 square meters of most standardized workshop, production equipment and testing instruments. At present, there are a series of stereotyped products such as type A (3a, 4a, 5a), X and so on, as many as 25 varieties have been put on the market.

The products are widely used in natural gas, oil refining, petrochemical, steel, light industry, air separation oxygen production and alcohol dehydration and other industrial fields, and have many successful examples in the deep drying, purification and separation of large and medium-sized industrial equipment at home and abroad. Xuefeng not only has many users in China, but also exports its products to developed countries such as Europe and the United States.

Shanghai Xuefeng has a certain scale of production, with three assembly lines with an annual output of more than 3000 tons of molecular sieves, and has passed the ISO9001-2000 standard Lloyd's quality management system certification, and Xueshanguan is a registered trademark of the product. In order to meet the needs of users, another automatic assembly line with an annual output of 6000 tons was installed in 2008.

Shanghai Xuefeng has introduced and digested the production technology of similar foreign products. The raw powder produced by our own Xueshan Industrial Company is added with clay strengthening agent. After kneading, roasting and activation, the appearance is beige or light gray. We can also produce strip and ball products of different specifications according to customer requirements. In accordance with the domestic (industry) standards of molecular sieves and referring to the main technical indicators of similar foreign products, Shanghai Xuefeng Molecular Sieve has formulated the technical standards for molecular sieve enterprises (QB/SF2690-99).The main testing items and indicators are shown in the sample. At the same time, eight types of molecular sieve products have been tested by Shanghai Research Institute of Chemical Industry ( the domestic molecular sieve national standard and industry standard drafting unit ) and other authoritative organizations, and all quality indicators have reached or exceeded relevant domestic and foreign technical standards.
