Calculate the quantities of gas and liquid formed when 7.5 lb moles of mixture of 60% methane and 40% ethane are brought to equilibrium at -40 °F and 600 psia based on Appendix 1. The equilibrium tie-line should be clearly indicated in the diagram.

Please help me answer at least all of the given questions. Thank you.

1) "Boiling Points" - Txy and xy diagrams. The vapor-pressure for the system n-octane & n-decane is available (spreadsheet): a) Using Raoult's Law and if needed Antoine's Equation calculate and plot the Txy diagram for a total pressure of 101.325kPa. b) Plot the xy data for this system at a total pressure of 101.325kPa.

1) Ethanol-Water Separations. We wish to separate ethanol from water in a sieve-plate distillation column with a total condenser and a partial reboiler. There are two feed streams: Thermal State subcooled liquid* saturated vapor *Feed 2 condenses 0.25 moles of vapor for every mole of feed. The bottoms product should be 2% (mol) ethanol and the distillate should be 72% (mol) ethanol. Feed Flowrate (mol/hr) ZF 1 0.4 2 0.3 200 300 Notes: • The reflux ratio is equal to (1.0) and the feeds are to be input at their optimum location(s). • Both feeds are being input into the column, e.g. this is not intended to be solving for two unique columns but just one that has two input feed streams. • Equilibrium data for Ethanol-Water at 1 bar is shown in the table. You may also identify /use other experimental data (web sources, library) for this system. a) What are the flowrates of the distillate and bottoms products? b) What are the flowrates of liquid and vapor on stages between the two feeds…
