Molecular sieve 4A

Molecular sieves are crystalline metal aluminosilicates having a three-dimensional interconnecting network of silica and alumina tetrahedra with uniform pore size. These pores have diameters 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 generally used for the simultaneous removal of water (Dehydration) and sour gas such as CO2, H2S, in addition some of light and heavy thiol from both gas and liquid feed stream. 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 sodium type of zeolite molecular sieve adsorbent, available in different shapes. It has an effective pore opening of about 4 angstroms (0.4 nm). It can adsorb most polar molecules with kinetic diameters less than 4 Angstrom and exclude those larger 

 High adsorption rate and capacity

 High physical properties

 Hydrothermal stability


GSorb-410 is conventional grade of 4A molecular sieve Which has a lot of uses in the industry. It is available in different shapes spherical cylindrical  trilobe and can be used as water, CO2, H2S or hydrocarbon adsorbent

✔ Dehydration of natural gas, syngas, air, hydrogen    ✔ 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

✔ Dehydration of acidic hydrocarbon    ✔ Dehydration of natural gas stream with amine content

GSorb-440 is specially used for drying of liquid hydrocarbon streams as well as syngas treating in various industries

✔ Kerosene drying       LNG drying      LPG drying    ✔ Hydrocarbon, Ammonia, Methanol removal from gas stream
