discussions about cellulosic ethanol, greenhouse gas emissions, or corn production are not included here, but are additional considerations when making energy efficiency decisions. Dry mill ethanol plants are evolving and the processes are being revised with each new plant and retrofit. For this report, the process shown in Figure 1 is

The block flow diagram of the corn to ethanol process is found below the process flow diagram. The per gallon of ethanol energy and water results are shown in Table 12. These averages were found by summing the 4 Process flow diagram for ethanol from Molasses. Page 20. Madhucon Sugar & Power Industries Limited.

Ethanol Process Calculation Ethanol conversion rates and extents Fermentation C 6 H 12 O 6 Æ2C 2 H 5 OH+ 2CO 2 + Heat Fermentinggg, one mole glucose, results in 2 moles of ethanol and 2 moles of carbon dioxide. On a weight basis: 180 g of glucose Æ92 g ethanol and 88 g Carbon dioxide i.e. Ethanol = 0.51 glucose (w/w); Carbon dioxide=0.49 glucose(w/w)
Using yeasts or bacteria to convert the sugar into ethanol and CO2 3. Distilling the ethanol out of the fermentation broth 4. If necessary, dehydrating the ethanol. PRODUCTION OF ETHANOL FROM SUGAR CANE Sugar cane contains 12-17% total sugars of which 90% is saccharose and 10% glucose and fructose. The wash then flows to analyzer column and alcohol is separated from the mother liquor wash by distillation process. Analyzer cum degasser column which operated under vacuum where in alcohol is separated and the vapour consisting of 45% v/v alcohol is transferred to pre-rectifier where in the alcohol is concentrated to 95 % v/v.
Bio-ethanol is an environmentally friendly fuel for vehicles that normally run on.

As an energy source, Figure 3 shows a vapor-liquid equilibrium diagram for the ethanol-water system at atmospheric pressure. The diagram shows mole percent ethanol in the liquid (X axis) vs mole percent ethanol in the vapor (Y axis). The plot could also be made for volume percent in the liquid vs volume percent in the vapor and the equilibrium Figure 1.

Process flow diagram of the purification step of ethylene production from ethanol. In the beginning, the ethylene stream is cooled to –23 °C. Then, it passes through an expansion valve, which reduces the temperature further to –28 °C by dropping the pressure from 27 to 22 bar.
In this work, the key role that process design plays potential to positively impact the cost of ethanol production via gasification. Building on a design report published in 2007, NREL and its subcontractor Harris Group Inc. performed a complete review of the process design and economic model for a biomass-to ethanol process via indirect gasification.
