After that, your instructor ask you a question: If the two feed streams afe entered to the column directly each at its optimal location, how many number of plates you need for the given separation and at which plate should you added each feed streams? How do you compare the obtained results?

The following vapor pressure was obtained for phenol and ortho$-$cresol:
