Abstract: In this paper, a new approach using artificial neural network and genetic algorithm for the
optimizationof the thermally coupled distillation is presented. Mathematical model can be
constructed with artificial neuralnetwork based on the simulation results with ASPEN PLUS.
Modified genetic algorithm was used to optimize themodel. With the proposed model and
optimization arithmetic, mathematical model can be calculated, decisionvariables and target
value can be reached automatically and quickly. A practical example is used to
demonstratethe algorithm.
