Question:
One million pound-moles per day of a gas of the following composition is to be absorbed by n-heptane at -30?F and 550 psia in an absorber having 10 theoretical stages so as to absorb 50% of the ethane. Calculate the required flow rate of absorbent and the distribution, in lbmol/h, of all the components between the exiting gas and liquid streams.
