Can you draww the flowchart question 4 and question 5 ?

Question 5 (20 pts). A steady state process consisting of an absorption tower and a stripping tower is used to separate the components of a gas containing 28.0mole% carbon monoxide (CO) and the balance ethane. A stream of this gas is fed to the bottom of the absorber. A liquid containing 0.485mole% dissolved CO and the balance ethanol is recycled from the bottom of the stripper and fed to the top of the absorber. The product gas leaving the top of the absorber contains 1.12mole%CO and essentially all of the ethane fed to the unit. The CO rich liquid ethanol solvent leaving the bottom of the absorber is fed to the top of the stripper and a 100 moles/h stream of nitrogen gas (N2) is fed to the bottom. Ninety percent of the CO in the liquid feed to the stripper comes out of solution in the column, and the nitrogen/ CO stream leaving the column passes out to the atmosphere through a stack. The liquid stream leaving the stripping tower is the 0.485mole%CO solution recycled to the absorber. The absorber operates at temperature Ta and pressure Pa and the stripper operates at Ts and Ps. Ethanol may be assumed to be nonvolatile, that is, none enters the vapor phase in either column and N2 may be assumed insoluble in ethanol. a) Taking a basis of 70moles/h of product gas leaving the top of the absorber, draw and label a flowchart of the process. For the stripper outlet gas, label the component molar flow rates rather than the total flow rate and mole fractions. Do the degree-of-freedom analysis and write in order the equations you would solve to determine all unknown stream variables. b) Circle the variable(s) for which you would solve each equation (or set of simultaneous equations). c) Calculate the fractional CO removal in the absorber (moles absorbed/mole in gas feed) and the molar flow rate and composition of the liquid feed to the stripping tower. Question 4 (20 pts). A liquid mixture of 35 mole % n-hexane (H),30 mole % n-octane (O) and the balance n-decane (D) is fed to a distillation column at steady state. The bottoms product which has a flow rate of 88moles/h contains 97 mole %D and balance O.95% of D in the feed is recovered in this stream. The overhead product from this first column is fed to a second distillation column. The overhead product from the second column contains 95% of the H in the feed to this column. The composition of this stream is 93mole%H and the balance O. a) Draw the flowchart of the process and perform degrees of freedom analyses. b) Calculate all the unknown variables for the process.
