$1.$Leaching of Oil from Soybeans in a Single Stage. Repeat Example $12\mathrm{.}9-1$ for single$-$ stage leaching of oil from soybeans. The $100$ kg of soybeans contains $22$ wt $\%$ oil and the solvent feed is $80$ kg of solvent containing $3$ wt $\%$ soybean oil. $1\mathrm{.}552\mathrm{.}0$ kg$,$ yA$10\mathrm{.}239,$ v$1=50\mathrm{.}0$ kg$,$ xA$1=0\mathrm{.}239,$ N$1$ Ans. LEXAMPLE $12\mathrm{.}9-1.$ Single$-$Stage Leaching of Flaked Soybeans In a single$-$stage leaching of soybean oil from flaked soybeans with hexane, $100$ kg of soybeans containing $20$ wt $\%$ oil is leached with $100$ kg of fresh hexane sol$-$ vent. The value of N for the slurry underflow is essentially constant at $1\mathrm{.}5$ kg in$-$ soluble solid$/$kg solution retained. Calculate the amounts and compositions of the overflow Vi and the underflow slurry L$1$ leaving the stage.
