Alcohol making process can be divided into five distinct steps: harvesting and crushing grapes. fermentation, distillation, and packaging. Alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy. producing ethanol (product) and methanol (undesired product) in the presence of yeast namely Zymomonas mobilis. CH,0.(sugar) – 2C,#,0H(athanoi) + 2CH,OH(methanol) In order to produce high quality of white wine, 70 wt% of sugar in aqueous solution was fermented at 40°C. for 500 days. Reaction conversion was 45%. However, this process will produce methanol as undesired product. Methanol is a poison to humans or will at least make them very sick, macimum allowable concentration of methanol in a wine is 0.5 mol%.

Alcohol making process can be divided into five distinct steps: harvesting and crushing grapes, fermentation, distillation, and packaging. Alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol (product) and methanol (undesired product) in the presence of yeast namely Zymomonas mobilis. CH,0.(sugar) - 2C,H,0H(sthanol) + 2CH,OH(methanol) In order to produce high quality of white wine, 70 wt% of sugar in aqueous solution was fermented at 40°C. for 500 days. Reaction conversion was 45%. However, this process will produce methanol as undesired product. Methanol is a poison to humans or will at least make them very sick, maximum allowable concentration of methanol in a wine is 0.5 mol%. Methanol can be removed from wine via single stage separation (flash) tank operated at a fermenter temperature and P = 100 mmHg A Ethanol 8.04404 1554.3 222.65 Water 7.94917 1657.462 227.02 Methanol 10.07247 157.499 238.88 Glucose 6.99893 1474.68 213.69 log P = A - (T + C) Pin mmg Hg ant Tin °C Your task is to determine the composition of fermenter product, and prove that flash calculation methods are applicable for this problem. Calculate the ratio between vapor and liquid product(V/L) of flash tank and calculate the composition of vapor and liquid product of flash tank.
