In the propanizer column, if the optimum RR which minimizes the total cost (TC) has been determined as 5.7, estimate the total cost (TC), capital cost (FC), and operating cost (VC) in $/yr using the additional information given below. For Distillation Columns, the capital cost of the whole column is considered as FC and the operating cost of the column through condenser and reboiler duties is the VC. - Total Cost (TC)= Fixed Cost (FC)+ Variable Cost (VC) - Purchased Equipment Cost: Ce=a+bSn where a,b : cost constants; S : size parameter; n : exponent for that type of equipment (Towler and Sinnot, 2nd Ed., 2013) - Operating Cost \( (\$ / \mathrm{yr})=\left(2.0 * \mid\left.( ight. \) Total Duty in \( \left.M W) ight|^{0.65} ight) * 10,000 \)
