GSorb-400 series (4A)

Molecular sieves are crystalline metal aluminosilicates having a threedimensional interconnecting network of silica and alumina tetrahedra with uniform size pores. These pores have diameter about 3-10 angstrom, thus larger molecules exclude while smaller molecules (such as water) can be adsorbed easily. According to this property, molecular sieve technology is widely used for the simultaneous removal of water (Dehydration) and mercaptans from both gas and liquid feed streams. Dehydration is a crucial operation in natural gas conditioning as it reduces the potential for corrosion, hydrate formation and freezing in process equipment and transportation pipelines. 4A molecular sieve is a sodium type molecular sieve zeolite adsorbent, available in different shapes. It has an effective pore opening of about 4 angstroms (0.4 nm). It will adsorb most molecules with kinetic diameters of less than 4 angstroms and exclude those larger. 4A molecular sieves are usually used for drying in various industries

 High adsorption rate

Low and stable pressure drop due to high physical strength

 High adsorption capacity



GSorb_410 is basic form of 4A molecular sieve Which has a lot of uses in the industry. It is available in different shapes spherical cylindrical Pellet and Trilobe and can be used as water or hydrocarbon adsorbent

✔ Dehydration of Natural gas, syngas, air, hydrogen and other solvent

✔ Removing traces of CO2

✔ Air dehydration in air break unit of buses, truck and locomotives


GSorb-420 is used for dehydration of acidic hydrocarbon and natural gas streams where regeneration reflux or carryover of water/ amine occurs during operation. Because of its special formulation, it has high stability to thermal shocks and also is resistance to hydrothermal damaging operation condition. Furthermore it can minimize coke formation phenomena
