1700 kmol/h of a liquid mixture of NBR and water enters at the top of a column containing an NBR mole fraction of 0.32. After an NBR removal of 77%, the liquid mixture leaves the equipment through the bottom of the tower. For its part, the gas used to carry out the separation (water vapor + NBR) has a molar fraction of 0.035 NBR, since it comes from a recycling stage. The gas flow to be used (Kmol/h) must be 1.8 times the minimum. a. What are the values of X1, x1, X2, X2, Y1, Y1 & L2? (8 Points) b. Determine the value of Ls (4 Points) c. Determine the minimum Vs value (show on the graph how you did it) (16 Points) Use the graph provided for this. D. Determine the value of Vs (4 Points) e. Determine the value of Y2, y2, V2 & V1 (8 Points) f. Draw the line of operation on the corresponding graph (6 Points) Use a different graph than the previous one so that you do not get confused. gram. In the case of an ideal countercurrent-multistage process, determine (graphically) the number of stages necessary to carry out said separation. (7 Points) Use the graph where you present the line of operation. H. Graphically determine the values of x & y (lowercase) for each ideal stage and plot them on a "box" flowchart. (12 Points)
