Molecular Sieve 4A

Molecular sieve 4A is a material used to adsorb molecules with a kinetic diameter of less than 4 angstroms. Larger molecules are excluded by the substance. A special feature of the molecular sieve is its porosity and the ability to filter complex mixtures and compositions. In fact, the sieve is an aluminosilicate with a type a crystal structure. Most often, the material is used in industry for cleaning certain products. The substance is gray in color and has a spherical or granular shape.

Using a 4A molecular sieve

As already mentioned, the 4A molecular sieve is most often used in industry to adsorb straight-chain gas, oxygen, nitrogen, or carbohydrate molecules. However, the substance is not suitable for use with aromatics or branched-chain carbohydrates.

The most common application of molecular sieve 4A:

1. Drying and removal of CO₂ from natural gases, liquefied gases or air.
2. Removal of ammonia, carbohydrates and methanol from gas streams in cleaning or transportation systems.
3. In the air systems of buses, trucks, or locomotives (specially modified connections are used).
4. For drying a variety of goods or products that are not resistant to moisture (the molecular sieve is pre-sorted into special packages).

The molecular sieve is delivered in cardboard boxes. It is important to store it in a closed package from the open air, as the substance absorbs moisture well. The sieve can be subjected to the regeneration process by heating to a temperature of 250-300 degrees Celsius, or by lowering the pressure, when the substance has lost its properties due to pressure drops.

Advantages of using a 4A molecular sieve

The molecular sieve allows efficient and economical cleaning processes on an industrial scale. Due to its high productivity and reliability, this method can significantly reduce investment costs for the filtration process, as well as ensure high-quality industrial production, transportation or storage.
