13x Molecular Sieve Desiccant Chemical Industrial Gas Dehydration Unit
Overview
Xi’an lvneng 13X Molecular Sieve is the sodium form of the type X crystal and has a much larger pore opening than the type A crystals.It has the highest theoretical capacity of the common adsorbents and very good mass transfer rates.

Typical Application
1.Water, dioxide, hydrocarbons removal
2. General industrial gases drying
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
10.Removal of water and carbon dioxide in PSA oxygen generation system
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.
