Molecular Sieve 3A Desiccant is available in 4x8 and 8x12 bead sizes and shipped in 330 pound drums. Molecular Sieve is typically used for special process applications. Pressure dew points to -100°F may be achieved with molecular sieve depending on the dryer design and operating conditions.

Applications: Multi-purpose. Molecular Sieve 3A is used for the dehydration and purification of various hydrocarbon and non-hydrocarbon gas and liquid streams. Also used for the drying of unsaturated hydrocarbon streams such as cracked gas, propylene, butadiene, and acetylene. The use of 3A Molecular Sieve for ethanol production is becoming very popular. The 3A Molecular Sieve pore size excludes most hydrocarbon molecules from adsorbing, while allowing water adsorption.

Molecular Sieve 4A Desiccant is available in 4x8 and 8x12 bead sizes. Purchasing 4A Molecular Sieve 330 lb drums is the most cost effective, but we also offer 4A Molecular Sieve in 25 lb pails and 50 lb bags. Molecular sieve is a sodium aluminosilicate. It has a fixed pore size according to the material specified, a 4 Angstrom pore size being the most common (1 Angstrom - 3.94 x 10-9 inches) Because of its high comparative cost, it is normally used for special process applications. Pressure dew points to -100°F may be achieved with molecular sieve depending on the dryer design and operating conditions.

Applications: Multi-purpose. Molecular Sieve 4A is used for the dehydration and purification of various hydrocarbon and non-hydrocarbon gas and liquid streams.

Drying and removing of CO2 from natural gas, LPG, air, inert and atmospheric gases, etc.

Drying of organic liquids such as refrigerants, LPG, and gasoline.

Removal of hydrocarbons, ammonia and methanol from gas streams (ammonia synthesis gas treating).

Molecular Sieve 5A Desiccant is shipped in 330 pound Steel Drums. Molecular sieve is a sodium aluminosilicate. An alkali metal alumino-silicate, in the calcium form of the Type A crystal structure. Type 5A will adsorb molecules with critical diameters up to 5 Å angstroms. All molecules which can be adsorbed on Molecular Sieve types 3A and 4A can be adsorbed on Type 5A.

Applications: Used for the dehydration and purification of various hydrocarbon and non-hydrocarbon gas and liquid streams. It is used for the separation of straight and branched chain hydrocarbons, sweetening and drying of natural gases and the production of high purity hydrogen.

Molecular Sieve 13X Desiccant is shipped in 330 pound drums. Molecular sieve is a sodium aluminosilicate. An alkali metal alumino-silicate, in the calcium form of the Type A crystal structure. An alkali metal alumino-silicate, in the sodium form of the Type X crystal structure. Type 13X will adsorb molecules with critical diameters up to 10 Å angstroms. All molecules which can be adsorbed on Molecular Sieve types 3A, 4A, and 5A can be adsorbed on type 13X.

Applications: 13X Molecular Sieve is used for the dehydration and purification of various hydrocarbon and non-hydrocarbon gas and liquid streams.

Drying and sulfur compound removal from natural gas, LPG and other petrochemical liqudis and gases.

NH3 and CO2 removal from gas streams.

Drying and CO2 removal from air.

The carbon molecular sieve (CMS) is a sorbent desiccant that has no polarity. The primary purpose of carbon molecular sieve desiccant is to separate nitrogen from air. It has the performance to absorb oxygen in the air under changing pressure of normal temperature, so it can gain rich nitrogen gas. Traditional rich nitrogen in plant air is produced to adopt deep freezing method, that is to make air liquefy under low temperature, separate oxygen and nitrogen through rectification. Its most remarkable characteristic is that N2 has little impurity content, N2 concentration and air current can be adjusted according to the requirements, and can gain high purity N2 with less than 5ppm O2 content and lower than -60¡æ dew point through refine.
