Chemistry

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


a. What is the mole fraction of B in the air coming out of theprocess?

b. For an inlet flow rate of 2000 ft3/min of air saturatedwith B, what would be the flow rate of the liquid B stream(lb/min)?

c. If the process could cool the stream down to 50ï‚°F insteadof 80ï‚°F, what would be the outlet mole fraction of B in thiscase?



Note:
Vapor pressure of B at 80ï‚°F = 0.5067 psia
Vapor pressure of B at 130ï‚°F = 2.221 psia MW of B = 20

Heat capacity of liquid B = 0.87 (btu)/(lb)(ï‚°F)
