CAS 1318-02-1 2.5mm 3A Molecular Sieve Air Dryer

Product description

3A molecular sieve has a pore size of 3A (1A=0.1nm), which is mainly used to adsorb water, and does not adsorb any molecules with a diameter greater than 3A. It is suitable for the drying of gases and liquids and the dehydration of hydrocarbons. It can be widely used in the deep drying of petroleum cracked gas, ethylene, propylene and natural gas. According to the characteristics of industrial applications, the molecular sieve we produce has faster adsorption speed, more regeneration times, higher crushing strength and anti-pollution ability, which can improve the utilization efficiency of molecular sieve and prolong the service life of molecular sieve. , The first choice desiccant necessary for gas and liquid phase deep drying, refining and polymerization in the chemical industry.

3A molecular sieve Used in various liquid dry, for example, ethanol, air, refrigerant, natural gas, methane gas, unsaturated hydrocarbon and cracking gas, ethylene, propylene, butadiene and so on.

3A molecular sieve technical Index:

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.
