A stream of 5.00 wt% oleic acid in cottonseed oil enters an extraction unit at a rate of 100.0 kg/hr. A separate stream of propane enters the unit. Propane is able to dissolve oleic acid but cannot mix with the cottonseed oil. Two streams exit the unit: One stream of propane that contains 90% of the oleic acid that enters the process; and a second stream that contains all of the cottonseed oil along with the remaining oleic acid. The concentration of oleic acid in the propane stream is 6.15 wt%. (a) Draw and label a flow chart for this process. Perform a degree of freedom analysis around the extraction unit. (b) Determine the flowrate (kg/hr) of propane entering the process.
