D17. On a Robeson (1993) plot (log-log plot of selectivity versus oxygen

D17. On a Robeson (1993) plot (log-log plot of selectivity versus oxygen permeability in Barrer) the upper bound for separation of oxygen from nitrogen plots as a straight line. Approximate values of end points are P02 = 0.0001 Barrer, 002-N2 = 42.0; and P = 10,000 Barrer, 02-N2 = 1.9. Barrer = 10-10 [cc STP cm]/[cm s cm Hg]. a. Find the equation for the straight line. 02 b. If we need an 02-N2 = 8.0, what is the maximum value of P, that can be obtained?
