code class$=$"asciimath"$>$A ternary mixture of A$,$B and C are to be separated using either a direct or indirect sequence. Which sequence would you recommend and why? Data: The ternary mixture flows ay $250$kmo$($l$)/($h$)$ and the mole fraction of A$,$B and C in the mixture are $0\mathrm{.}6,0\mathrm{.}3$ and $0\mathrm{.}1$ respectively. The utilities required are cooling water and low pressure $($LP$)$ steam. Cooling water is used at $320$K$^(-1)$ and costs $$1\mathrm{.}30$hkJ$^(-1)$yr$^(-1)$ and LP steam is provided at $420$ K and costs $$34\mathrm{.}00$hkJ$^(-1)$yr$^(-1).$
