Two materials, A and B, are to be separated using two unit operations, 1 and 2. The feed has 10 tons/h A and 4 tons/h B. The split (fraction of material rejected by each operation) is given in Table P6-14.
a. Which sequence of operations, (1 2) or (2 1), will yield the greatest recovery of material A?
b. What will be purity of material A using that sequence?
c. What will be the efficiency of separation for the entire process train with regard to material A using the Worrell-Stessel equation?
