The reference I am following
https://www.ou.edu/c... of Freedom.pdf
So according to the reference we have two degrees of freedom
So if is specify number of stages and and feed locations are the systems fully defined?
So in my case I have strict feed concertation A & B
Distillate purity defined 0.99
Bottom purity defined 0.99
So that means I have only two variable to play with No of stages and feed locations, I will get Reboiler duty and condenser duty out of the.
The partial condenser that I have will just add (one) stages to both no of equations available and total no of variables.
Now for absorption column
Feed locations are fixed But I can change the solvent concentration and flowrates and no of stages. To calculate the column cost.
The purity of top product C 0.99 and bottom products D0.99 are fixed.
Hear I Also see two degree of freedom
Ami I correct??
