Question

A gas stream contains 18.0 mole% hexane and the remaindernitrogen. The stream flows to a condenser, where its temperature isreduced and some of the hexane is liquefied. The hexane molefraction in the gas stream leaving the condenser is 0.0500. Liquidhexane condensate is recovered at a rate of 1.50 L/min. (a) What is the flow rate of the gas stream leaving thecondenser in mol/min? (Hint : First calculate the molar flow rateof the condensate and note that the rates at whichC6H14 and N2 enter the unit mustequal the total rates at which they leave in the two exitstreams.) (b) What percentage of the hexane entering the condenser isrecovered as a liquid?
