What is Pervaporation Membrane Technology
Pervaporation is derived from two energy-efficient processes: permeation and evaporation. It achieves continuous separation of the permeable component on the properties of different dissolution and diffusion rates in the membrane module.
The process is especially suitable for the separation of near-boiling point, constant-boiling point mixtures, isomeric substrates, and compounds with poor thermal stability that are difficult or impossible to separate by the ordinary process of distillation, extraction, or adsorption.
It has obvious economic and technical advantages for the removal of trace water from organic solvents and mixed solvents, and for the separation of small amounts of organic pollutants in wastewater.
Compared with the traditional solvent recovery process, PV has outstanding features of high efficiency, low energy consumption, high recovery, convenient operation, safety, environment friendly, etc.

How to Produce Anhydrous Ethanol with a Minimum 99.5% Purity
Producing anhydrous ethanol with a minimum 99.5% alcohol concentration is a complex process that requires careful attention to detail. Raw material selection, pre-treatment, fermentation, distillation, dehydration, and quality control are all crucial stages in the production process. By following these steps, producers can ensure to produce high-quality anhydrous ethanol that meets the required purity standards.
China is now the third largest producer and applicant of biofuel ethanol in the world following Brazil and the United States. The keys to determine the future prospects of high purity ethanol production are manufacturing cost and process technology, especially the cost of ethanol preparation and high purity separation.
Currently, the most efficient technology in this respect is the molecular sieve membrane permeation vaporization ethanol-water separation technology, which has a bright market prospect with hundreds of millions of dollars of market demand every year.
Pervaporation Membrane Dehydration Technology
Pervaporation molecular sieve membrane is a layer of uniform molecular sieve crystal synthesized on a ceramic carrier. A molecular sieve has regular pore structure, which utilize the principle of screening for the separation of substances of different molecular size.
Factors Affecting Permeation Vaporization Performance
Permeation vaporization membrane separation technology is a process that separates or enriches a portion of an organic mixture by selectively absorbing and decomposing the components in the mixed solution. As the diffusion rate of each component in the membrane is different.
