Unlike fossil Fuels Ethanol is one of the renewable energy sources produced by decomposing of sugars. Traditionally Distilleries are producing it by decomposing Molasses which is by product of sugar manufacturing process. The challenge is to increase the production of ethanol and getting high yield by changing the raw material i.e. using Sugarcane juice instead of Molasses. Further process changes, Design changes and Biological changes are studied.
Ethanol is an essential part of the fuel industry in chemical engineering. Since humans are using organic and inorganic compounds those may be naturally found or prepared by some chemical and physical processes. Coming to the automobile industry ethanol usage in petrol was initially 5% and now it has been increased to 10%. It is having a huge impact on rising petrol prices. Now there are chances that the percentage of ethanol in petrol can be again increased and raised to 30%. In the future, we might be running all vehicles 100% on ethanol only as we can see a lack of sources of crude oil and they are going to get vanished soon. For many years we are producing ethanol from molasses with good efficiency.
In recent days if we see the demand for ethanol has increased as its part of fuel and energy. To fulfil that demand we need to produce ethanol and other resources also. Ethanol production from the raw material is dependent on the content of Reducing Sugar in that particular material. As we know sugarcane juice is having an abundant amount of sugar content that can be reduced and ethanol can be obtained more efficiently. The thesis is related to the optimization of the process for production of ethanol from sugarcane juice. Some design, process, and biological changes are to be observed and some suggestive measures to be given.
India is leading sugarcane producer in the world but a huge amount of sugarcane remains unprocessed due to unavailability of the facilities. Main agenda of this study is to utilize the unprocessed sugarcane for production of ethanol.

Scope of Work
In order to achieve the objective, the following scopes have been identified and to be applied:
Cumulative Observation, I
Sample ratio components is 1:5
It is combination of juice in the ratio of 1:4 that means 85 ml of concentrated juice is added to 415ml of water.
2.5 gm of urea is added to the solution while adding 2.5gm of yeast.
The above sample is prepared to treat with Fali Fueling activated fermentation yeast for fermentation and below mentioned readings are taken on 25th January 2022 on the time mentioned in the table
Table -2: Cumulative observation table I
Cumulative Reading II
Sample ratio components is 1:4
It is combination of juice in the ratio of 1:4 that means 100 ml of concentrated juice is added to 400ml of water.
2.5 gm of urea is added to the solution while adding 2.5gm of yeast.
The above sample is prepared to treat with Thermosacc XL fermentation yeast for fermentation and below mentioned readings are taken on 25th January 2022 on the time mentioned in the table.

Material Balance
Fig -2: Overall Material Balance
X + Y=2 ……………[i]
Ethanol in Feed = Ethanol in Distillate + Ethanol in Bottom
0.2 * 2 = 0.82X +0.02Y ……………[ii]
Y = 20 - 41X ……………[iii]
Put equation [i] in [iii],
X + (20 – 40X) = 2
X + 20 – 41X = 2
10 – 20X = 1
-20X = 1 – 10
X = 0.45 kg/hr.
Now equation [i] becomes,
Y = 2 – 0.45
Y = 1.55 kg/hr.
Distillate Flow rate = 0.45 kg/hr.
Bottom Product = 1.55 kg/hr.
Ethanol in Distillate = 0.82 * 0.45
= 0.369 kg/hr.
Ethanol in Feed = 0.2 * 2
= 0.4 kg/hr.
= 92.25 %
CONCLUSION
To fulfill the demand of fuel market and to utilize the unprocessed sugarcane we can produce ethanol directly from sugarcane syrup instead of molasses. The yeast used for molasses for fermentation is not that much usefull because of excess sugar present, hence changing the yeast can give us better outcomes. As shown in material balance part we have derived 92% alcohol recovery by this process.
