CREST PROVIDES TECHNOLOGY FOR MANUFACTURE OF ANHYDROUS ALCOHOL (GASHOL)

AZEOTROPIC DISTILLATION

AN ENTRAINER BENGENE / CYCLOHEXANE IS ADDED TO THE RECTIFIED SPIRIT AND IT IS DISTILLED EMPLOYING DEHYDRATION, RECOVERY COLUMNS AND DECANTER. 
 

PERFORMANCE : 
 

RECTIFIED SPIRIT (94.5 95.0%) 1065 ~ 1070 LTR / KL AA
STEAM   1.7 ~ 1.9MT / AA
POWER  60KW ~ 65KW / AA
COOLING WATER (MAKE UP) 4 ~ 5M3 / AA
ENTRAINER  1.8 ~ 2.0 KG / AA

 

MOLECULAR SIEVE TECHNOLOGY

RECTIFIED SPIRIT VAPOURS ARE FED TO ONE MOLECULAR SIEVE COLUMN (SYNTHETIC ZEOLITES ).  AN ANHYDROUS  ALCOHOL  IS CONDENSED AS FINAL PRODUCT.

SIMULTANEOUSLY, SECOND MOLECULAR SIEVE COLUMN AT LOW PRESSURE IS REGENERATED USING PART OF ANHYDROUS ALCOHOL VAPOURS EMPLOYING VACUUM PUMP.  tHE LEAN ALCOHOL (CONTAINING 69% ALCOHOL + 31.% WATER ) IS CONDENSED AND REDISTILLED TO 94.5 95% CONCENTRATION IN MAIN COLUMN .
