| dc.description.abstract | Equipments used in bioethanol production unit depends on the selection of raw
material, process and plant size. In this research, the bioethanol production unit
used durian peel as raw material was designed with capacity process of 100 liters.
The designed equipments were pre-treatment equipments, fermenter and
distillation unit where the pre-treatment equipments were consisted of cooking
tank, crusher and pressured tank. Cooking tank was made of carbon steel SA-285
Grade C with 45,10 cm of diameter and 90,21 cm of height. Crusher was used to
smooth durian peel and required power of 3,061 hp. Pressured tank was made of
carbon steel SA-283 grade C with 45,10 cm of diameter and 90,21 cm of height.
Fermenter tank was designed with 43 cm of diameter and 86 cm of height which
was equipped with two manual paddle impeller of 30 cm in diameter. Distillation
tank was made of stainless steel with 48 cm of diameter and 54 cm of height,
which was equipped with heater to heat the liquid of fermentation process and
cooling tank to cool vaporised bioethanol. The time required for one cycle of
fermentation with batch process was 7 days and 7 hours. While the time required
for one cycle of bioethanol production with batch process was 8 days and 4 hours.
The feasibility of bioethanol production unit in which consisted of fermenter tank
and distillation tank under condition process of 7 days and yeast concentration of
6% and distillation temperature of 80o
C was tested. The results obtained were
8,98% of bioethanol concentration during fermentation and 74,96% of bioethanol
concentration during distillation. | en_US |
