13x Molecular Sieve Desiccant
Introduction
13X molecular sieve is used commercially for desulphurization of liquefied petroleum gas, natural gas and liquid hydrocarbon. It is also used for dehydration of gas and liquids.

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, botane…) 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
Regeneration:
Molecular sieve Type 13X can be regenerated by either heating in the case of thermal swing processes; or by lowering the pressure in the case of pressure swing processes.
To remove moisture from a 13X molecular sieve, a temperature of 250-300°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C, or mercaptan or CO2 levels below 2 ppm.
The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process
Attention
Pls avoid damp and pre-adsorption of organic before running, or it must be reactivated.
