Molecular sieve drying is an effective dehydration method. Its working principle is to use molecular sieves to adsorb water molecules in ethanol for drying.
Procedure as below:
1.Pass the ethanol through the molecular sieve bed, and the molecular sieve adsorbent will adsorb the water molecules in the ethanol.
2.Under certain temperature conditions, the molecular sieve bed is heated to desorb adsorbed water molecules to achieve the regeneration of the molecular sieve.
3.This process is a cyclic operation that achieves continuous drying of ethanol.
Compared with traditional methods such as distillation and dehydrating agent adsorption, molecular sieve drying of ethanol has the following advantages:
1. Easy to operate and can be performed continuously or intermittently.
2. Save energy and only require lower regeneration temperature.
3. There is no serious equipment corrosion problem.
4. It has a wide range of applications and can be used for drying various kinds of water-containing ethanol.
It should be noted that different types of molecular sieves may have different adsorption effects on ethanol and water. Therefore, it is necessary to select the appropriate type according to the actual operations and working situation.
At the same time, in order to ensure the drying effect and product quality, attention must be paid to controlling parameters such as feed speed, temperature, and pressure during operation.
