การกลั่นเอทานอลจากข้างฟ่างหวานด้วยกระบวนการรีฟลักซ์ (Distillation Ethanol From Sweet Sorghum by Reflux Distillation)

Abstract

The objectives of this thesis were to study factor of Initial Ethanol concentration and temperature for distillation Ethanol from Sweet sorghum to high concentration by Reflux distillation, were size of pot 20 L and heating by internal heater in pot for boiling Ethanol – water mixtures were initial low concentration to evaporated and condensed to high concentration by Reflux distillation . Ethanol - water mixtures were initial concentration 10.0 % by volume can produce Ethanol by temperature for distillation was 90 - 93o C and result Ethanol concentration to 58.4 % by volume, next step distillation repeat second times at Ethanol 58.0 % by volume and temperature for distillation Ethanol was 79 – 80o C result can produce Ethanol concentration to 85.2 % by volume, next step distillation repeat third times at Ethanol 85.0 % by volume and temperature for distillation Ethanol was 76 – 77o C result can produce Ethanol concentration to 91.2 % by volume and distillation repeat fourth times at Ethanol 90.0 % by volume and temperature for distillation Ethanol was 76 o C can produce Ethanol final concentration to 92.3 % by volume.
