Operating Strategies and Optimum Feed Tray Locations of the Fractionation Unit of BTX Plants for Energy Conservation
E-mail:
Operating strategies and optimum feed tray locations were studied in a typical fractionation process of a BTX plant in Korea in order to reduce energy consumption. Control systems with fixed V/F or R/F ratios could be recommended for various feed compositions. By choosing the optimum feed tray location for the columns, about 16% of energy consumption could be reduced.
