In Figure P11.6 you will see two successive liquid separations columns operating in tandem in the steady state (and with no reaction taking place). The compositions o the feed and products are as shown in the figure. The amount of W₂ is 20% of the feed. Focus only on the material balances. Write down the names of the material bal ances for each column treated as separate units (one set for each column), along with the balances themselves placed next to the names of the balances. Also, place an as- terisk in front of the names of the balances that will comprise a set of independent equations for each column. Write down in symbols the unknowns for each column_ Calculate the degrees of freedom for each column separately. % A 60 B 20 C 20 Feed 100 kg % A 15 B 30 C 55 ▲ P₁ O 3 W₁ 2 P₂ W₂ % A 10 B 85 C5 % A 0.2 в 7 C ?
