n-Hexane is used to extract oil from soybeans. (See Problem 6.24.) The solid residue from the extraction unit, which contains 0.78 kg liquid hexane/kg dry solids, is contacted in a dryer with nitrogen that enters at 85°C. The solids leave the dryer containing 0.05 kg liquid hexane/kg dry solids, and the gas leaves the dryer at 80°C and 1.0 atm with a relative saturation of 70%. The gas is then fed to a condenser in which it is compressed to 5.0 atm and cooled to 28°C, enabling some of the hexane to be recovered as condensate. Make a detailed flowchart with the unknowns and degree of freedom chart a) Calculate the fractional recovery of hexane (kg condensed/kg fed in wet solids).
