Abstract
Distillation is by far the most important separation process in the chemical industries, but is also one of the most energy intensive units, thus significant efforts are being placed on optimizing the design and operation of both new and existing distillation systems to achieve potentially significant energy and/or capital savings. This work introduces an optimization strategy based on combining a preliminary stochastic optimization method, either Particle Swarm Optimization (PSO) or Genetic Algorithm (GA), which is used to perform a global search, with a deterministic optimization method, Outer Approximation method (OAERAP), for the local search. A dividing wall distillation column and a hybrid distillation/pervaporation superstructure is used to illustrate the methodology. The performance of stand-alone PSO, stand-alone GA, combined PSO/OAERAP and combined GA/OAERAP, are compared and it is shown that the PSO/OAERAP combination provides the optimal design in a significantly shorter time and can also optimize a superstructure efficiently. This work also presents the use of a parallel computing function when performing stochastic optimization, which significantly speeds up the optimization.
