A to C please

Propylene is produced by the dehydrogenation of propane. The product stream leaving a dehydrogenation reactor is found to contain 900mol/s propane, 99.75mol/s propylene, and 95mol/s of H2. This stream is passed to a distillation column, with the distillate containing all of H2, most of propylene, and 0.555% of the molar flow rate of the propane that enters the column. The bottoms from the column, which is recycled back to the reactor, has a propylene molar flow rate equal to 5% of that in the distillate. The distillate is then passed to a second distillation column in which all of the H2 is recovered in the distillate and all of the organics (propane and propylene) are recovered in the bottoms. a) Construct a process flow diagram for this system. b) Perform a degree of freedom analysis for the system containing the two distillation columns (you do not need to worry about the dehydrogenation reactor). c) Evaluate the molar flow rates for all streams assuming that the process operates at steadystate
