Fresh halibut livers containing 25.7 wt % oil are to be extracted with pure ethyl ether to remove 95% of the oil in a countercurrent multistage leaching process. The feed rate is 1000 kg of fresh livers per hour. The final exit overflow solution is to contain 70 wt % oil. The retention of the solution by the inert solids (oil-free liver) of the liver varies as follows (C1), where N is kg inert solid/kg solution retained and yA is kg oil/kg solution: N yA 4.88 0 3.50 0.2 2.47 0.4 1.67 0.6 1.39 0.81 Calculate the amounts and compositions of the exit streams and the total number of theoretical stages.

Question
Fresh halibut livers containing 25.7 wt % oil are to be extracted with pure ethyl ether to remove 95% of the oil in a countercurrent multistage leaching process. The feed rate is 1000 kg of fresh livers per hour. The final exit overflow solution is to contain 70 wt % oil. The retention of the solution by the inert solids (oil-free liver) of the liver varies as follows (C1), where N is kg inert solid/kg solution retained and yA is kg oil/kg solution:
| N | yA |
| 4.88 | 0 |
| 3.50 | 0.2 |
| 2.47 | 0.4 |
| 1.67 |
0.6 |
| 1.39 | 0.81 |
Calculate the amounts and compositions of the exit streams and the total number of theoretical stages.
