In a hexane recovery unit, hexane is evaporated to nitrogen gas in an evaporator. A stream of inlet nitrogen-hexane at the temperature of 30 "C with a dew point of 5°C enters the evaporator and leaves the unit at 25 "C with nitrogen saturated with hexane The pressure of inlet and outlet stream was measured to be at 1 atm (absolute). In order to evaporate 100 kg/h of hexane, what is the required flow rate of gas coming ator? Perform a material balance on the evaporator and determine the to the ev
