Abstract / Description of output

Pressure Swing Adsorption (PSA) has recently attracted attention as an efficient separation technology for CO2 capture. However, complex multibed/multi-steps PSA cycles are necessary to obtain high purity CO2 efficiently. The complex behaviour of the performance with respect to the process variables requires the development of automated tools for the design of PSA cycles.

In the present paper we introduce a multi-criteria design framework for multibed/multi-step PSA/VSA (vacuum swing adsorption) cycles for CO2 capture. A simplified, yet reliable, simulation tool has been developed to reduce computational requirements. A custom multi-objective genetic algorithm has been used to generate approximations of the Pareto front. A targeted fitness function has been defined, which encourages the evolutionary procedure to broaden the extent of the Pareto front.
