Faster adsorption rate, More regeneration times Higher crush strength, stronger anti-pollution capacity, lower wear rate, longer lifespan.
The preferred desiccant of gas and liquid in Petroleum and chemical industry for Deep drying, refining and the polymerization.
1, Dehydration of liquids (such as Ethanol)
2, Dehydration of air
3, Dehydration of Refrigerant
4, Desiccation of natural gas and methane gas
5, Desiccation of unsaturated hydrocarbons, pyrolysis gas, ethylene, acetylene, propylene, butadiene
The molecular sieve shall be stored at room temperature, in which the relative humidity does not exceed 90%, and be not exposed to air, and prevented against water, acids and alkalizes.
1. The product cannot be exposed in the open air and should be stored in dry condition with the air-proof package.
2. The product should be regenerated after a certain period of adsorption. The appropriate regenerated temperature would be better below 350°C.
