The product from a reactor contains 60% w/w A, 25% w/w B and 15% w/w C. The final saleable product is required to contain 90% A. The mixture can be purified in a distillation column but under the conditions possible in the column the product produced is 100% A with the bottom product containing no A. It is possible to mix the reactor products and the distillation product. Calculate:
1) The amount of reactor product that could bypass the distillation system to give the maximum amount of saleable product at minimum cost.
2) The amount and composition of the waste material.
