Steady State Optimization of the Cyclohexanol Production Unit
نویسنده
چکیده
The main objective of this paper is to cover the first stage of a real time optimization project for a cyclohexanol production multiphase reactor. Firstly, the optimization problem is stated and the upper layer of a two layers real time optimization approach is solved off-line. Some equations of the steady state process model show to yield a difficult NLP. The mathematical steady state model is validated with industrial data and it is based on mass, energy and momentum balances. Several simulation results are presented which show that the resulting optimization problem is a complex one. Failure of convergence may occur depending on the code for solving the NLP, but improved operating conditions may be reached.
