Specific constant characteristics as well as initial operating parameters that are present during the operation of the facility are acquired. A computational simulation of the chemical processes in the reactors then takes place, wherein results of a measurement of the chemical composition of the product at the outlet side of the last reactor is also included. A computational simulation of the chemical processes in the reactors with different varied operating parameters is subsequently carried out and set of optimised operating parameters is determined from the computed chemical composition.
