3A Molecular Sieve Manufacturer as Air Drying Desiccant In Nature Gas Methane Drying

Short Description:

Type 3A has an effective pore opening of about 3 angstroms (0.3nm). This is large enough to allow in moisture, but excludes molecules such as unsaturated hydrocarbons which can potentially form polymers; and this maximizes lifetime when dehydrating such molecules.

Description

3A molecular sieve named Potassium A (3A) molecular sieve, the bore diameter is 3A, Mainly used for water absorption, can absorb critical diameter 3A molecular, can not absorb any molecular which diameter is no greater than 3A molecular. According to the application on the industrial characteristics,it has the faster absorption,more regeneration frequency,a higher crushing strength and ability to resist pollution,improve the utilization efficiency of the molecular sieve and prolong the service life of the molecular sieve,it’s the first desiccant to use in deepth dry, chemical refined and polymerization in oil and gas industrial.

Application

a) Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien)
b) Cracked Gas Drying
c) Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required.
d) Drying of highly polar compounds, such as methanol and ethanol
e) Drying of liquid alcohol,CNG.
f) Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.
g) Drying of CNG.

Regeneration

Molecular sieve Type 3A 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 3A molecular sieve, a temperature of 200-230°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C.

The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.
