The distillation column shown below is used to separate compound A from compound B in an adiabatic
Question:
a) Take 100 moles of the feed stream as a basis. What is the net heat supplied in this process?
b) Again, taking 100 moles of the feed stream as the basis, what is the heat removed at the condenser (QC), and the heat inputted at the reboiler (QR)? (Make sure your answer for QC is negative, indicating that heat is removed by the condenser.)
c) Suppose now that instead of the condensed liquid from the top of column being split into two equal streams to form the reflux and the overhead product, it is split into two streams, with the reflux being 3 times the overhead product. As before, take a basis of 100 mol of feed and determine the net heating requirements for the process and the heat removed in the condenser and added in the reboiler.
