A 100 kmol/h stream that is 97 mole% carbon tetrachloride (CC14) and 3% carbon disulfide (CS2) is to e recovered from the bottom of a distillation column. The feed to the column is 16 mole% CS2 and 4% CC14, and 2.5% of the CC14 entering the column leaves in the overhead (top of the column). a) Draw and label a flowchart of the process and do the degree-of-freedom analysis. b) Calculate the mass and mole fractions of CCl4 in the overhead stream and determine the molar low rates of CCl4 and CS₂ (kmol/h) in the overhead and feed streams.

Question
Transcribed Image Text:A 100 kmol/h stream that is 97 mole% carbon tetrachloride (CC14) and 3% carbon disulfide (CS₂) is to
be recovered from the bottom of a distillation column. The feed to the column is 16 mole% CS₂ and
84% CC14, and 2.5% of the CCl4 entering the column leaves in the overhead (top of the column).
(a) Draw and label a flowchart of the process and do the degree-of-freedom analysis.
(b) Calculate the mass and mole fractions of CCl4 in the overhead stream and determine the molar
flow rates of CCl4 and CS₂ (kmol/h) in the overhead and feed streams.
