Markus Auer: Improvement of kinetic model for steam cracking furnaces

Steam Cracking is an important process for the petrochemical industry transforming saturated hydrocarbons at elevated temperature in the presence of steam into smaller unsaturated hydrocarbons, mainly for production of lighter alkenes such as ethylene and propylene, as well as butadiene and aromatics. In this master's thesis, simulation and optimization techniques of the open source framework CasADi were applied on steam cracking furnace simulation. An adequate model of the tubular reactor coil with a reduced set of chemical reactions was implemented. Simulation results for initial and boundary value problems were compared with reference results. The optimization problems covered in this thesis include the maximization of product yield by variation of feed stock or heat flux profile. Additionally, mathematical parameter estimation techniques were applied for adaptation of the kinetic model to measured data.
