Calculate the degrees of freedom in "column 1"

3 ТopI Top II Column I Feed Column II Bottom I Bottom II
Transcribed Image Text:3 ТopI Top II Column I Feed Column II Bottom I Bottom II
The flowsheet below shows a process with two distillation columns in series, where the distillate (top product) of the first column is fed to the second one. It is known that: • The feed to the column contains 30 wt% X, 45 wt% Y, and 25 wt% Z. • The "Bottom l" product contains only X and Y, with a 80 wt% X • The "Top I" stream contains only Y and Z. Both "Bottom II" and "Top II" stream contain only Y and Z. The "Top II" stream contains 72% Z. The "Bottom Il" stream contains 30% Y and flows at a rate of 220 kg/hr.
