Second-law analysis of a distillation. column c3 in figure 1.8 separates stream 5 into streams 6 and 7, according to the material balance in table 1.5. the sepa- ration is carried out at 700 kpa in a distillation column with 70 plates and a condenser duty of 27,300,000 kj/h. using the fol- lowing data and an infinite surroundings temperature to, of 298.15 k, compute: (1) the duty of the reboiler in kj/h; (b) the irreversible production of entropy in kj/h-k, assuming condenser cooling water at 25°c and reboiler steam at 100°c; (c) the lost work in kj/h; (d) the minimum work of separation in kj/h; and (e) the second-law efficiency. assume the shaft work of the reflux pump is negligible.
