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.The resulting differential-algebraic equation (DAE) optimization problem has been
