The increasing demand for ethyl acetate as an important raw material in various industries demands the need for advanced production processes and effective recovery and dehydration technologies.

The traditional production processes, although widely used, face challenges such as high energy consumption, low separation efficiency, and environmental pollution.

The pervaporation technique has emerged as a promising alternative due to its low energy consumption, no pollution, and good separation effect.

The optimization of the pervaporation process conditions can significantly improve its separation performance, making it a highly efficient and economic option for the recovery and dehydration of high-purity ethyl acetate on an industrial-scale production line.

The use of molecular sieve membranes in the pervaporation process has shown outstanding chemical stability and separation performance, making it a promising technology for the separation of ethyl acetate-water systems.

Methanol is an important chemical with a wide range of applications. With the advantages of high temperature stability, low volatility and excellent clean energy properties, it is widely used in the production of chemicals, solvents, fuels and fungicides.
Effective recovery and purification of methanol is essential for many industries, including the chemical, pharmaceutical and energy sectors. By following the optimized process flow and using advanced process equipment and technology, you can ensure that you recover and purify methanol effectively and produce high quality anhydrous methanol suitable for your specific application.

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.
