PROBLEM #1: Consider the ethanol-water separation column with a feed of 2000 lb-mol/hr containing 7.5 wt% ethanol. You want a desired concentration of ethanol close to the azeotrope. Any alcohol that goes with the water stream is economical loss (waste). Assume the following uncertainty in the mean value: Year 1: current values, Rest of the years: use a 4% inflation rate for prices (the rest does not change). Assume next that around the mean value in each year values fluctuate following a normal distribution around the mean with the following standard deviations: Feed flowrate=5%, Feed Ethanol concentration= 25 %, Energy cost=85%, cooling water cost=30%. Assume that the capital costs as calculated using P&T and the Marshall and Swift index are accurate. a)
