It is desired to process 1000 kg/h of bran (A) from a cerealcontaining 20% oil and no solvent. Benzene is used as a solvent.Temperature and pressure are constant and equilibrium data areshown in the table. For countercurrent extraction where 662 kg/h ofpure solvent are admitted. A raffinate with 5% oil is obtained instep ānā. Determine the number of steps needed.
