Imagine a substance with the following points on the phase diagram: a triple point at 0.5 atm and - 5 °c; a normal melting point at 20 °c, a normal boiling point at 150 °c; and a critical point at 5 atm and 1000 °c. the solid-liquid line is "normal" (i. e. positive gradient). roughly sketch and label the phase diagram. annotate all important areas and points.

A100 kmol/h stream that is 97 mole% carbon tetrachloride (ccl4) 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% ccl4, and 2% of the ccl4 entering the column is contained in the overhead stream leaving the top of the column. calculate the mass and mole fractions of ccl4 in the overhead stream, and determine the molar flow rates of ccl4 and cs2 in the overhead and feed streams. 12. mw_ccla- 153.82; mw_cs2-76.14.
