AB The following work shows the application of DASPK in EcosimPro™ with the aim of to calculatethe partial derivatives of the state variables with respect to the decision variables (sensitivities) andto improve the dynamic optimization. The implementation of DASPK was tested in three examples:disturbance rejection in a stirred tank with heater, the optimal production policy of hydrogen in amodel of a hydrodesulfuration plant and the optimal trajectory of the feeding in a batch bioreactor.The sensitivities with DASPK was compared with another two possible options: obtain the gradientsusing finite differences and to solve the extended system with the analytical expressions of thesensitivities. The outcomes shows that the implementation of DASPK is a suitable option to ensureoptimality in dynamics optimization without the need of writing the sensitivities by hand,nevertheless the CPU time must be improved to become this option attractive.
