Q.1: 100 kg of an aqueous solution of B, containing 10% B is to be extracted using S solvent. Water and Solvent are immiscible within the range of concentration involved. Determine percentage extraction of B if the extraction is carried out in three stages cross-current using 50 kg of S in each stage. Equilibrium data are as follows: by weight kg B/kg water: kg B/kg S: 0.030 0.074 0.16 0.21 0.029 0.070 0.156 0.24

Question
Q.1: 100 kg of an aqueous solution of B, containing 10% B
is to be extracted using S solvent. Water and Solvent are immiscible within
the range of concentration involved. Determine percentage extraction of B
if the extraction is carried out in three stages cross-current using 50 kg of
S in each stage.
Equilibrium data are as follows:
by weight
kg B/kg water:
kg B/kg S:
0.030 0.074
0.16 0.21
0.029 0.070
0.156 0.24
