A continuous distillation column is used to produce an 85% ABV spirit as distillate product from an 8% ABV wash. Reflux is established through a partial condenser, also known as dephlegmator, using the wash as the cooling fluid in the partial condenser. The wash is supplied at 50 kmol/h at an initial temperature of 20 C, and leaves the partial condenser at 75 C. The pre-heated wash is then heated further up to its bubble point using steam, before being fed into the column. The bottom product contains 0.2 mol% ethanol (0.65% ABV). Use assumptions where required, and provide justification. 1. Find the distillate flowrate in kmol/h 2. Calculate the reflux ratio R that the dephlegmator achieves
