3.Gas purification in air separation process
4.Natural gas, liquefied petroleum, liquid hydrocarbons(propane, butane…) dehydration
5.Sulfur dioxide and mercaptan removal
6. General gas (such as compressed air, permanent gas) deeply drying
7.Ammonia synthesis gas drying and purification
8.Aerosol propellant desulfurization and deodorization
9.Carbon dioxide removal from cracked gas

Attention
zeolite 3.0-5.0mm molecular sieve 13x can’t be exposed in the open air and should be stored in dry condition with the air-proof package.
zeolite 3.0-5.0mm molecular sieve 13x can be regenerated after a certain period of adsorption.
The appropriate regenerated temperature would be better below 350°C.
