    ● Process simulation and optimization

CoSPE is concentrated on the simulation and optimization of chemical/biological processes. Using NLP (Non-Linear Programming), MINLP (Mixed-Integer NLP) and MOP (Multiobjective Optimization Programming) techniques, optimum design/operation parameters are identified in terms of energy-efficiency, cost reduction, and environmental impacts.
An integrated environment has been developed for several specific purposes such as simulation, optimization and parameter estimation of SMB, PSA (pressure swing adsorption) and batch chromatographic processes, FAST-Chrom/SMB/PSA.
The following papers concern the simulation and optimization of SMB (simulated moving-bed) processes .
