The final design parameter to be studied in this chapter is the locations of the two fresh feed-streams. Up to this point we have assumed that the lighter reactant fresh feed F0A is introduced on the bottom tray of the reactive zone (NS + 1) and the heavier reactant fresh feed F0B is introduced on the top tray of the reactive zone (NS + 1 + NRX). This configuration seems like a logical choice. However, the fresh feeds could be introduced on trays inside the reactive zone. The question is how this affects the design, primarily in terms of energy consumption because this is our major economic performance criterion.
