A saturated llquld mbxture of ethane, propane, n-butane, n-pentane, and n-hexane Is to be separate by distilation such that 95% of the propane is recovered in the distillate and 90%6 of the butane recovered In the bottoms. Wighter than Iight key and heavler than heavy key components are assume to be recovered in distillate and bottom products, respectively. Required DATA are glven below: 1. Identify LGGHT and HEAVY KEV components. [2] 2. Calculate relative volatility values for all components W.r.t. the HEAVY KEY component [3]] 3. Calculate the minimum number of theoretical stages required (accurate up to 2 decimal points) [2] 4. Calculate the value of minimum reflux ratio (accurate up to 3 decimal polnts) [8] 5. Which HYsys module can validate your answers (Q3 \& Q4)? What fluld package should you use? [1+2=3 Val calculations for solving nonlinear equations must be shown and Tolerance =0.01 can be used as termination criteri
