We take the inorganic permeation vaporization membrane as the key developing direction by combining the characteristics of the permeation vaporization process with the requirements of customers.
The process is made to measure for your process demand, and Greatwall Process and Control provides the most suitable membrane separation technology for you.
The NaA zeolite membrane dehydration equipment is specially designed for various solvents dehydration and concentration.
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 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.
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.
