10.5 To what temperature must air be cooled to remove 40% of its heptane vapor content? The airstream is presently at 150 C and 1 atm, and contains 50,000 ppm heptane. 10.6 If the airstream of Problem 10.5 were flowing at 50 m/min, calcu- late the amount of money (in dollars per day) that could be saved by condensing 40% of the heptane. Assume that solvent (liquid) heptane has a specific gravity of 0.75 and sells for $1.00/liter. 10.5 To what temperature must air be cooled to remove 40% of its heptane vapor content?
