In ethanol production, using molecular sieve to remove water is the most popular method. Compared with other ethanol dehydration processes, the advantages of molecular sieves are: simplicity, low installation cost, easy operation, environmental protection, etc. SNOWPEAK developed molecular sieves specifically for ethanol dehydration in the 1990s, which are used to dry ethanol produced from edible feedstock, cellulosic feedstock, and synthetically produced ethanol.
13X molecular sieve refers to the sodium form of the X-type crystal structure, which is an alkali metal aluminosilicate. 13X type molecular sieve can adsorb molecules whose critical diameter is not more than 10A. SNOWPEAK 13X-HP molecular sieve has high oxygen and nitrogen separation performance and sufficient oxygen production rate. Due to its special production technology, the molecular sieve has excellent adsorption and desorption properties. It is mainly used for PSA/VPSA oxygen generating units to implement oxygen and nitrogen separation, making industrial and medical oxygen enrichment
SNOWPEAK 13X-APG molecular sieve is dedicated to air cryo-separation industry, applicable to any size of air cryo-separation devices. The adsorption capacity of carbon dioxide and moisture was further improved, to avoid frozen tower phenomenon in the distillation process. Good kinetic characteristics can maximize the adsorption effect of the existing adsorption bed, and reduce the size of the newly designed adsorption bed, thus decrease energy consumption.
3A molecular sieve is an alkali metal aluminosilicate, also called KA molecular sieve or 3A zeolite molecular sieve, mainly used to adsorb water. SNOWPEAK 3A molecular sieve has faster adsorption speed, more regeneration times, higher crushing strength and anti-pollution ability, which can improve utilization efficiency and prolong service life. It’s really the preferred desiccant necessary for deep drying, refining and polymerization of gas and liquid in petroleum and chemical industry.
4A molecular sieve is one of the most consumable molecular sieves used in industry, its selective adsorption of water is higher than any other molecule. SNOWPEAK 4A molecular sieve adsorbs water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene and other molecules with diameters no more than 4 angstroms. Usually used for gas and liquid drying, but also for refining and purification of certain gases or liquids, such as the preparation of argon.
5A molecular sieve is commonly known as CA molecular sieve, can adsorb any molecule with diameter less than 5 angstroms. Mainly used in n-isomeric hydrocarbon separation, PSA separation, and co-adsorption of water and carbon dioxide. With high selective adsorption and fast adsorption speed, SNOWPEAK 5A molecular sieve is especially suitable for pressure swing adsorption(PSA) industry, which can adapt to any size of oxygen, hydrogen, carbon dioxide and other gas production PSA devices.
Pressure swing adsorption(PSA) molecular sieve is a synthetic silicon aluminate crystal with different silicon-alumina ratios to form different types of molecular sieve, and after the exchange of different metal cations into the same type of different categories of molecular sieve.
SNOWPEAK PSA molecular sieve has high oxygen and nitrogen separation performance and sufficient oxygen production rate. Due to its special production technology, the molecular sieve has excellent adsorption and desorption properties. It is mainly used for large, medium and small PSA oxygen generating units to implement oxygen and nitrogen separation, making industrial and medical oxygen enrichment.
The life of most refrigeration systems depends on when the refrigerant leaks. The leakage of the refrigerant is caused by the harmful substances produced by the refrigerant and the trace moisture that corroded the pipeline. Molecular sieve has the characteristics of low dew point control, high strength, low wear, and does not destroy the chemical stability of refrigerant. The refrigerant should choose a specific molecular sieve. SNOWPEAK XH-5 molecular sieve is suitable for some chemically very stable refrigerants, XH-7 molecular sieve is suitable for all refrigerants, and XH-9 molecular sieve is specially used for R-401A and B mixture of HFC-152a freezing system desiccant.
The insulating glass desiccant can absorb moisture and residual organic matter at the same time, to keep the glass mooth and transparent even at very low temperature; can reduce the strong internal and external pressure difference due to huge temperature changes, to solve completely the distortion and breakage problem caused by the expansion or contraction of the insulating glass related to ordinary desiccants.
Activated alumina desiccant is a spherical activated alumina made by special process. Its own properties are non-toxic, odorless, non-pulverizing, insoluble in water, white spherical in appearance and strong in water adsorption. Under certain operating conditions and regeneration conditions, its drying depth is as high as the dew point temperature below -70℃, which is manly used for drying of liquids and gases.
Activated powder desiccant or activated zeolite powder, is obtained by calcining molecular sieve raw powder at high temperature. Beause the raw powder loses most of the moisture during the calcination process, the activated zeolite powder has strong activity and can be directly used in production as an adsorbent with selective adsorption.
