3.6mm 4*8 Mesh 5A Molecular Sieve Desiccant
Product introduction
5A molecular sieve is a kind of molecular sieve (alkali metal alumino silicate) whose aperture is 5Å. Sometimes, it is also called 5A zeolite molecular sieve or calcium molecular sieve.Type 5A has an effective pore opening of 5 angstroms (0.5 nm). It will adsorb molecules with a kinetic diameter of less than 5 Angstrom and exclude those larger.
It is especially suitable for PSA adsorber applications where it may be used for the separation of normal- and iso- paraffins (C4 to C6 species), in PSA hydrogen purification and in oxygen concentrators.

Application
The strong ionic forces of the divalent calcium ion makes it an excellent adsorbent to remove water, CO2, H2S from sour natural gas streams, while minimising COS formation. Light mercaptans are also adsorbed.
It is also used for the separation of normal- and iso paraffins.
Production of high purity N2, O2, H2 and inert gases from mixed gas streams.
Store
Storage: Room temperature, relative humidity not more than 90%; not directly exposed to the air; avoid water, acid and alkali.
Packing: cardboard drum or carton packaging.
Note: Avoid direct exposure of molecular sieve to air.

Regeneration
1. Removal of water: it depends on the pressure, temperature and water content of the regeneration gas. Under normal circumstances, the dry gas at 200~350℃ will pass through the molecular sieve bed for 3~4 hours under the pressure of 0.3~0.5kg/cm to bring the outlet temperature to 110~180℃ and cool.
2. Removal of organic matter: replace organic matter with water vapor, and then remove water.
Package
Packed in iron drums, (according to the product model) net weight 125kg, 135kg, 140kg, or according to user needs.
Factory information
Shanghai Xuefeng Molecular Sieve Co., Ltd. adopts the most advanced and fully automated assembly line molecular sieve production technology in China, and has positions for dosing, kneading, extrusion, drying, roasting and packaging. The main equipment includes pelletizing machine, hardening cylinder, kneader, extruder, belt dryer, rotary roasting furnace, vibrating screen, scale and other ancillary facilities. The production process parameters are all automatically controlled, and there is no paper recorder attached. , The results of the process parameters are comprehensively recorded, and at the same time, the operators of each position shall manually record the parameters every hour to ensure the traceability of the operation process. At the same time, the company pays attention to the inspection of intermediate products, and has set up sampling points for intermediate products in the ingredients, extrusion molding, and drying positions to ensure that the intermediate products meet the specified quality requirements.
