(b) A gas stream contains 18 mole% hexane and the remainder nitrogen. The stream flows to a condenser, where its temperature is reduced and some of the hexane is liquefied. The hexane mole fraction in the gas stream leaving the condenser is 0.05. Liquid hexane condensate is recovered (as pure hexane) at a rate of 1.50 L/min. The molecular weight and specific gravity of hexane are 86.17 g/mol and 0.659 respectively. (i) Draw and label a flow chart. (ii) Determine the molar flowrate of the liquid hexane condensate. (iii)Determine the molar flowrate of the condenser feed. (iv)Determine the molar flowrate of the gas stream leaving the condenser.

Transcribed Image Text:(b) A gas stream contains 18 mole% hexane and the remainder nitrogen. The stream
flows to a condenser, where its temperature is reduced and some of the hexane is
liquefied. The hexane mole fraction in the gas stream leaving the condenser is 0.05.
Liquid hexane condensate is recovered (as pure hexane) at a rate of 1.50 L/min. The
molecular weight and specific gravity of hexane are 86.17 g/mol and 0.659
respectively.
(i) Draw and label a flow chart.
(ii) Determine the molar flowrate of the liquid hexane condensate.
(iii)Determine the molar flowrate of the condenser feed.
