Thermo-feasibility optimization of multiple feed rate multicomponent distilation system

Abstract

Thermoexergetic rate profile, thermoexergetic-efficiency and thermoexergetic-destruction were used in combination with the view to determine the thermo-feasibility of multicomponent distillation system with multiple feed rate. Simulation was of a multicomponent distisllation system was carried out and the stage-by-stage system exergy analysis was carried out. Multiple feed rate base cases sensitivity results gave the most adequate and feasible thermo-exergetic rate profiles, efficiency ranges and destruction at the depropanizer and debutanizer. Overall system performance of multiple feed rate base case -30 ^oC design gave optimum overall system exergy destruction and efficiency. Multiple feed rate could ensure thermo-feasibility of the system and this can form basis for system performance and productivity improvement.
