Low Moisture Content Molecular Sieve Dehydration For Alcohol Production

Low Moisture Content Molecular Sieve Dehydration For Alcohol Production

Molecular sieve dehydration technology:

1,Molecular sieve dehydration: 95% (v / v) of liquid alcohol is heated to the proper temperature and pressure by feed pump, preheater, evaporator, and superheater ( For gas alcohol dehydration: 95% (V/V) gas alcohol directly through the superheater, after heating to a certain temperature and pressure ) , and then is dehydrated from top to bottom through the molecular sieve in the adsorption state. The dehydrated anhydrous alcohol gas is discharged from the bottom of the adsorption column, and qualified finished product is obtained after condensation and cooling.

2,Molecular sieve regeneration: After dehydration is completed by the adsorption column, the water absorbed in the molecular sieve is flash-evaporated by vacuum flash evaporation, and then condensed to be light alcohol, the molecular sieve reaches the adsorption state again.

The regeneration of the molecular sieve of the adsorption column is achieved by using the equipment such as vacuum pump, light wine condenser, and regeneration superheater. The regeneration process is divided into: decompression, vacuum extraction, flushing, and pressurize, the running time of each step is automatically controlled by the computer program.

The light alcohol obtained by condensation during the regeneration process is pumped to the light alcohol recovery device.

Work Site

Jiangsu Wulong Machinery Co., Ltd is located in the western suburb of Changzhou—an opening-up coasted city of Jiangsu. The company owns convenient transportation, facing Shanghai-Beijing Railway, Shanghai-Nanjing Expressway and Changzhou Airport in the north, and bordered new No. 239 Provincial Freeway.

Jiangsu Wulong Machinery Co., Ltd is a director unit of China’s Brewing Industry Association Ethanol Branch and a member of China’s Separating Machinery Industry Association. The company was established in 2000 restructuring by the original Changzhou Wujin Fermentation Engineering Machinery Plant (a municipal state-owned enterprise). The original plant was built in 1969. The company has five professional manufacturing branch offices at the moment; they are complete set of ethanol equipment manufacture branch office, crushing equipment manufacture branch office, heat exchanger manufacture branch office, decanter centrifuge manufacture branch office, and belt press filter manufacture branch office. Products are well sold to over 800 companies in over 30 provinces, cities and autonomous regions; some of them are exported to over 10 countries in Europe, Africa and Southeast Asia, and are well received by customers. The company now has more than 160 staffs and workers, 28 among that are various kinds of senior or middle professional technicians. The factory occupies an area of 24,000 square meters, and having a fixed capital of more than 30million Yuan. For dozens of years, the company has built long-term technical cooperative relations with more than ten domestic scientific and research institutes. The company has passed the authentication of ISO9001 Quality System in 2000, and strictly executes the quality system standards of ISO9001. Taking the objective of “excellent products, advanced technologies, long-term services”, the company will devote to the technical development of domestic fermentation and environment protection. Sincerely welcome the exchanges and cooperation with colleagues at home and abroad.
