Resumen:
In this work, the open loop dynamic optimization of a cryogenic process has been performed. The resulting differential-algebraic equation (DAE) optimization problem has been solved with an advanced simultaneous strategy that transforms the original problem into a large scale nonlinear program (NLP) through discretization of the entire set of variables by collocation on finite elements. Prior to this discretization, the original distributed parameter problem, which results from energy balances around heat exchangers, is transformed into an initial value problem by finite differences. The dynamic model provides profiles of controlled and manipulated variables, which are in agreement with available data.
