Most industrial liquids and gases utilize 4A zeolites for the dehydration process. The molecular sieve is potent to deliver the pure form of liquids and gases and keep them contaminate-free for a longer time. 4A adsorbing water molecules from certain liquids and gases to prevent severe damage in industries.
Molecular Sieve 4A is used as a desiccant in an array of industrial applications. 4A molecular sieve means the molecules with the pore size of 4A0 or 4 angstroms are used for the adsorbing process. It simply signifies that molecules with the pores size larger than 4a cannot be used for adsorption. Generally, they are the sodium forms of the Type A structure.
Type 4a has reliable adsorption speed, higher resistance quality, and stronger adsorption, which are enough to enhance product life. Such type of molecular sieve is perfect to remove the moisture from liquids and gases. It is a universal dehydrating agent used in polar and non-polar media. This type of molecular sieve is the perfect desiccant for low inlet, humidity, with the temperature below 30-35% RH.
4A molecular sieves can be available in the form of beads, pellets and powder form.
Molecular sieve 4A is considered as one of the best desiccants for a variety of applications that includes:
- For instrumental air drying (for ensuring a dew point of -60/-800C.
- Dehydration of drugs, electric components, and unpreserved chemicals when packed
- Removal of moisture in plastics and paints
- Drying of Refrigerants
- Drying of Natural gas, petroleum gas, and cracked gas
- Dehydration of ethanol
