Computation of the Optimal Value of Operating Parameters in a Reactor – Heat Exchanger System by Differential Evolution Techniques

In this research work, the modern soft computingtechnique of Differential Evolution (DE) algorithm is consideredto determine global optimal values of the operating parameters ina Reactor -Heat Exchanger (RHE) system. In addition, a penaltyterm is incorporated in the objective function and therebycomputing annual cost of the RHE system in terms of operatingand investment costs. A comparative study is also made withGenetic Algorithm (GA) in RHE system. Results clearly indicatethe supremacy of DE for global optimization of operatingparameters in RHE system. A convergence test is performed andreported here.
