What Is The Difference Between Drying Method By Distillation And By Molecular Sieve?

In the drying methods of the chemical industry, distillation drying and molecular sieve drying are two common methods. How to choose them in practical operation？Read on!

What is the advantages and disadvantages of distillation method?

Distillation technology is through heating, evaporation, condensation, collection and other steps to remove the moisture and other volatile impurities. It is suitable for the drying of a large amount of ethanol, however, it also has some disadvantages, such as it need to consume a lot of heat energy, and it can’t achieve the desired drying effect if the ethanol with high humidity, high dust content.

What is the advantages and disadvantages of molecular sieve?

Molecular sieve drying uses molecular sieves to adsorb moisture and other impurities in ethanol into its pores to achieve drying purposes. It has good drying performance, low energy consumption, reusable and can be adjusted for different ethanol and treatment volume. However, the disadvantage is that it needs to be replaced every 5-8 years.

In summary, both drying methods have their own advantages and disadvantages. Please choose it according to your actual working conditions. If you are interested in low input cost molecular sieve welcome contact us any time.
