Molecular sieve 3A is a potassium-sodium aluminosilicate with a pore size of 3Å (0.3 nm) also called zeolite 3A or zeolith 3A, is one type of aluminosilicate crystal. Kinetic diameter smaller than 3 angstroms will be adsorbed, otherwise, be excluded. The chemical formula is K12[(AIO2)12(SIO2)]·XH2O. Silicon to aluminum ratio: SiO2/Al2O3≈2. CAS Number: 308080-99-1. Molecular Sieves 3A are typically used for agents drying or pulling out moisture from products. Such as ethanol dehydration, natural gas dehydration, cracked gas dehydration, and refrigerant dehydration.

Ethanol Dehydration Grade Molecular Sieve have lower its water content, the higher quality of alcohol is produced. However, using typical multi-pressure distillation processes alone, the ethanol to water azeotopic ratio is at 95.5%, with a maximum of 97.2%. Further purification is needed to exceed the limits for a more refined final product.

An insulated glass unit is composed of two glass lites at least. These are separated by a space filled with air or a special gas (argon, krypton, SF6, etc.). The lites are supported and separated by a spacer and then sealed. Water from the air and solvents from the sealant can be trapped inside the unit. Water can also penetrate through the sealant during the life of the insulated glass unit. Both phenomena lead to fogging (water or solvent condensation on glass lite).

Natural gas must be dehydrated to remove water vapor. Water vapor causes the formation of hydrates, over saturation of natural gas, and corrosion of equipment. The high pressure increases saturation and creates more water vapor. Hydrates cause freezing and blocking of pipelines, valves, and other equipment, bringing production to a halt. Oversaturated gas does not meet pipeline specifications, which must be removed in order to sell.

As an adsorbent, molecular sieve should not be left exposed to open air and should be stored in dry conditions with air-proof packaging. This product should not be exposed to temperatures exceeding 230˚C (450˚F).
Molecular sieve 3A can be regenerated or activated either thermal regeneration method(Thermal Swing Adsorption, TSA); To remove moisture from a 3A molecular sieve, a temperature of 200-230°C (390-570°F)is required. Molecular sieve 3A can also be regnerated or activated by lowering the pressure in the case of pressure swing processes (PSA). A properly regenerated or activated molecular sieve can give moisture dew points below -100°C. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.

Luoyang Jalon Micro-nano New Materials Co., Ltd. JLPM series molecular sieves are mainly used for cryogenic drying of general industrial gases. The purification system in the air separation unit removes H2O and CO2, as well as natural gas and other hydrocarbon desulfurization (removal of H2S and mercaptans) and CO2.
It is worth mentioning that Yuntianhua United Commerce Co., Ltd. Company 52000 Nm3/Cryogenic air separation unit project. The design and manufacture method of the air separation unit by air, adsorber adopt vertical radial flow design, processing capacity of 311352 nm3 / h, 5.13 Bar (A) adsorption pressure, loading type my company JLPM3 efficient molecular sieve 92 tons, 107 tons of activated alumina, can ensure that the CO2 content in the air mean 1000 parts per million (2000 PPM) instantaneous equipment and stable operation, export CO2 molecular sieve < 0.1 PPM.
The fifth-generation high-performance molecular sieve JLPM1 is an advanced molecular sieve used in the pre-purification unit (APPU) of air separation equipment. Compared with previous generations, the fifth-generation high-performance molecular sieve JLPM1 has significantly improved CO2 adsorption capacity; the fifth-generation high-performance molecular sieve JLPM1 will bring multiple benefits to air separation designers and operators. For the design of the new air separation plant, the application of the fifth-generation high-performance molecular sieve JLPM1 can make the air separation occupy a smaller area, thereby reducing equipment investment and operating costs. The fifth-generation high-performance molecular sieve JLPM1 can also be used for the transformation of old equipment, which can reduce energy consumption or improveair separation processing capacity.
