QUESTION 1 A mature of 6% pentane, 54% hexane, 30% heptane and 10% octane are distilled at 1 atm. The goal is to recover 96 molls of hexanes in the overhead and 92 molW of heptane appears in the botlom products. The feed is bolling liquid. Table 1: A mixture of the composition with K-Value. 1.1. Defermine the Light and Heavy Key components for the system. (2) 1.2. Complete the table above and calculate the relative volatily. (12) 1.3. Using Underwoods method determine the range of the required value of (=1.2,1.3,1,35) 1.4. Determine the minimum neflur ratio (3) 1.5. Determine the minimum number of stages.

A solution of 9.3% acetaidehyde in toluene is to be extracted with water in a six stages co-current unit. If 32.1kg waten 100kg feed is used, what is the mass of acetaldehyde extracted and the final concentration? The equilibrium relation is given by: ( kg acetaidehyde/kg water) = 2.27(kg acetaldehyde/kg toluene)
