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.
