I have a final year project which is designing a distillation column (deethanizer). it is a theoretical design so it's not going to be applied in real life. By far i have calculated everything except the cost. i want to choose marshall and swift index (M&S) or CEPCI index to calculate the cost of the column, reboiler and condenser.
what equations should i use to calculate them and calculate the operating cost too.
if you can give me the equations directly i'll appreciate it.
Thanks in advance.
