In the production of soybean oil, dried and flaked soybeans are brought into contact with a solvent (often hexane) that extracts the oil and leaves behind the residual solids and a small amount of oil. Draw a flowchart of the process, labeling the two feed streams (beans and solvent) and the leaving streams (solids and extract). The soybeans contain 18.5wt% oil and the remainder insoluble solids, and the hexane is fed at a rate corresponding to 3.00kg hexane per kg beans. The solids stream leaving the extraction unit contains 37.5wt% hexane, all of the non-oil solids that entered with the beans, and 1.25% of the oil that entered with the beans. For a feed rate of 1250kg/h of dried flaked soybeans, calculate the mass flow rates of the extract and residual solids, and the composition of the extract
