Overview

Molecular sieve 3A is an alkali metal aluminosilicate, it is the potassium form of the type A crystal structure.
Molecular sieve 3A has an effective pore opening of about 4 angstroms, it adsorbs molecular with effective diameters smaller than approximately 3 angstroms. But excludes molecules such as unsaturated hydrocarbons.

Recommended Application:
·Drying of unsaturated hydrocarbons (e.g. ethylene, butadiene)
·Cracked gas drying.
·Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required..
·Drying of highly polar compounds, such as methanol and ethanol.
·Static,(non-regenerative)dehydration of insulating glass units, whether air filled or gas-filled.
·Dehydration of refrigerant.

Packing:
·55 gallon (150kg )air-tight iron drum.
·25 kg/carton, and each carton has inner PE bag.
·Other packing according to your requirement.
 
Instruction: Prevent molecular sieve from exposing directly to the air.
Warning: Molecular sieve adsorption activity is an exothermic reaction, any contact to human body is dangerous.
