3.0mm 3a Molecular Sieve Sphere

4×8 Mesh Type 3.0mm 3a Molecular Sieve Sphere

Product description

The pore size of 3A molecular sieve is 3 Å . It does not adsorb any molecular larger than 3 Å. It is an alkali metal alumino-silicate, the potassium form of the typ A crystal structure. It will adsorb, in sequence of adsorption rate, helium, neon, nitrogen and water.
According to the industrial application specialties, we endue our products with the characters of higher adsorption speed, stronger crushing and anti-contaminative resistance, more cyclic times and longer work-span. All these advantage have made it come to be the most essential and necessary desiccant in the fields of the deep drying, refinery, polymerization for cracked gases, ethylene, propylene and any other non-acidic gases or liquids in petroleum and chemical industrials.

Application

a) Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien)

b) Cracked Gas Drying

c) Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required.

d) Drying of highly polar compounds, such as methanol and ethanol

e) Drying of liquid alcohol

f) Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.

g) Drying of CNG.

3A molecular sieve technical Index:

Store

Room temperature, relative humidity not greater than 90% indoors: avoid water, acid, alkali, isolate air, and store in airtight.

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.
