High Purity First Set Ethanol Dehydration System Ethanol Purification Plant

High Purity First Set Ethanol Dehydration System Ethanol Purification Plant

60000 Tons Per Year Thailand'S First set Ethanol Dehydration System

Technology Application:

The new technology of dehydration with variable temperature and pressure(FTrPSA)is adopted, featuring in low energy consumption (each ton of ethanol products only consumes 0.1 ton od steam), High purity( the concentration of the ethanol products can exceed 99.995%) And high yield(The compared membrane separation method is of higher yield), And the dehydrated molecular sieve is the OEM designated by DAVY technology of UK, and the technology and devices are sold overseas.

Process principle

Molecular sieve adsorption method is a kind of technology which uses molecular sieve to adsorb and desorb ethanol vapor. Molecular sieve material is a kind of hard clay, which is made into granular or spherical material with controlled size micropores. Using 3A zeolite, the pore size is 3a, water molecule is 2.8A and ethanol molecule is 4.4a. Because ethanol molecule is larger than water molecule, water molecule can be adsorbed in the pore, ethanol molecule can not be adsorbed and rejected. When the water containing ethanol vapor passes through the molecular sieve adsorption bed, the molecular sieve adsorbs the water, while the ethanol vapor passes through the adsorption bed and becomes the dry ethanol product.
