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 |
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 .
PERFORMANCE
:
| RECTIFIED SPIRIT | 1055 – 1066 LT / KL aa |
| sTEAM (6 KG/CM2 9 ) | 0. 50 ~ 0.60 mt/KL Aa |
| pOWER (3 PHASE ) | 2.4-2.5 M3 KL Aa |
| cOOLING WATER ( 320 c ) | 10 ~ 15 KW / KL Aa |
| aIR (5 KG / CM2 9) | 4.8 – 5.0 NM3 / KL Aa |
