Vacuum Ethanol Dehydration System Alcohol Plant 304 Stainless Steel

Vacuum Ethanol Dehydration System Alcohol Plant 304 Stainless Steel

Sichuan Hongzhan 50,000 Tons/Year Alcohol Plant 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 discription

The decompression step is completed within a certain period of time through the vacuum system, which involves the vacuum system and the corresponding system condenser. The decompression step plays an important role in the whole analysis process. The regeneration effect of molecular sieve bed will directly affect the quality of the product. Therefore, the decompression process is the key to the engineering design of the device.

In the whole decompression process, the power provided by the system comes from the vacuum system. According to our company's previous ethanol dehydration engineering experience, water ring vacuum unit is selected to form vacuum in this scheme. The ethanol water mixture to be pumped is cooled by the regeneration condenser and then enters the regeneration buffer tank, and the non condensable gas is pumped out of the battery limit through the evacuation pipeline.
