A continuote process uses hexane to cutract vegetable oa from canola seed, Olt is miked with couched seeds and dissotves the oil from the solid part of the reed. Then the oilhexane miature is separated from the solld parts of the seed and sent on for Later refinement. This problen tocuies solely on the miving and separating of the oil from the seet. The process conshts of two units, a miver and a separator. The crushed canola seed flows into the mber at a pate of 10.0 (lgilinin]. The oil content of the seeds is 45 with with remaining imass being sobids which are not dissolved in the hexane. Pure hexane is added to the maver at a second streamat a rate of 50.0 ligglining. The material beaving the reiker flows into a sepurator whire the solids are removed conpletely in one streams but they are soaked with residual oif and hexane. The second stream lewing the sepurator has a total flow rate of 450ikg/min and a8.25wt. od and the balance heane and contalis no solds. A. Draw a process flow diagram and bbel all streaens with appropriate variables. Choose letters to represent the 3 species. 7. How many usetul contrd vplumes can we draw for this system? C. Pertorm a degree of freedom analysis foount uninowns and equations) for each control volume in pirt till and determine which control volumes an be solved first with the piven information. Explicity state the unkrowns and equations for each control volume. D.
