propyne and propane are light hydrocarbons produced by thermal and catalytic

“Cracking” of heavier petroleumfractions. Propyne and propane have the same boilingpoints,

but can be separated by distillation. Representative conditions are shown in the figure.

A mixture of propyne and propane must be separated by distillation. Estimated thermodynamic

values for the currents are in the table.

TASK: Use the values in the table and calculate the Minimum work required for separation:

̇_ ^ = ̇_ _ + ̇_ _ − ̇_ _ (The answer must be in MJ/h)
