Calculate outlet mole fraction, Physics

An air stream is saturated with a vapor (B) at 130°F and 1 atm pressure.  It is cooled down to 80°F where some of the B is condensed and separated from the vapor stream.  The remaining vapor stream is then reheated back to 130°F.

a) What is the mole fraction of B in the air coming out of the process?

b) For an inlet ?ow rate of 2000 ft 3/min of air saturated with B, what would be the ?ow rate of the liquid B stream (lb/min)?

c) If the process could cool the stream down to 50°F instead of 80°F, what would be the outlet mole fraction of B in this case?


 Vapor Pressure of B at    80°F = 0.5067 psia
 Vapor Pressure of B at  130°F = 2.221 psia
 MW of B = 20
 Heat capacity of liquid B = 0.87 (btu)/(lb)(°F)
