chemical engineering 5

The diagram below shows a circuit consisting of three (3) distillation columns that is being used to separate a feed stream A into four final products C, D, Fand G. The feed contains four (4) components labelled 1-4, whose mass fraction concentrations are shown as Xiri where i component and j stream. Assume that the circuit is operating at steady state with no reactions occuring 4,C 1, B 2,B 3, B 4, B 1,A 2,A 3.A 4,A Question Completion Sta 2,E 3,E 4, E 4,G How many independent mass balance equations can be written for this circuit? Only count mass-balance equations e. do not include Zixij 1 equations). Enter your answer as a whole number with no decimal places.

Explanation / Answer

There are 6 different components that cross the system boundaries in the overall scheme, hence there should be 6 independent mass balance equations written for this circuit.
