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 CasADi framework shall be applied. The capabilities and applicability are to be demonstrated for steam cracking simulation. An adequate simulation model of the tubular reactor coil with a reduced set of chemical reactions shall be implemented. Simulation results shall be compared to measurement data. Additionally, mathematical parameter estimation techniques shall be applied for adaptation of the kinetic model to measured data.
