Abstract: A method for configuring a control system for a process plant using a dynamic model of the process plant, the dynamic model being based on at least one of thermo fluidic correlations, thermo dynamic correlations, phenomenological correlations, and equations, and being based on geometry and/or topology of components of the process plant, the dynamic model receiving process parameters as input values, the dynamic model being adapted to represent a transition from one to another state of the process plant and the dynamic model covering the entire operating range of the process plant wherein the dynamic model is used in an offline mode, in which the dynamic model is used in stand-alone fashion, wherein, based on input and output values of the dynamic model, a behaviour of the process plant is predicted, and wherein, based on the predicted behaviour of the process plant, the control system is configured.

Abstract: A method for operating a process plant using a dynamic model of the process plant, the dynamic model being based on at least one of thermo fluidic correlations, thermo dynamic correlations, phenomenological correlations, and equations, and being based on geometry and/or topology of components of the process plant, the dynamic model receiving process parameters as input values, the dynamic model being adapted to represent a transition from one to another state of the process plant, wherein the dynamic model is used in an online mode, in which the dynamic model is used in parallel with the operation of the process plant, wherein signals from a control system of the process plant, the signals representing values of at least one first process parameter, are received and fed into the dynamic model.

Abstract: A remaining service life of a process-engineering apparatus through which fluid flows and which is embodied as a heat exchanger, column, or container for phase separation is acquired. A computing unit is mounted on the apparatus and coupled to a remote computing unit. Temperature measurement values are obtained by a plurality of sensors arranged in or on the apparatus. Mechanical stress is acquired as a characteristic variable not directly measurable from the measurement values of the temperature. The remaining service life is acquired from the mechanical stress. The mechanical stress is acquired by means of the computing unit and the mechanical stress and/or the temperature measurement values are transmitted to the remote computing unit, and the remaining service life is acquired there. Alternatively, the temperature measurement values are transmitted to the remote computing unit, and the mechanical stress and remaining service life are acquired there.

Abstract: The present invention relates to a method for determining a number of mechanical stresses (304) prevailing at different first locations in a material of a process engineering apparatus (1), wherein the number of mechanical stresses (304) prevailing at the different first locations in the material of the process engineering apparatus (1) is determined from a number of temperatures (301) prevailing at different second locations in the material of the process engineering apparatus using an empirical model (M3), the empirical model (M3) being trained by means of training data (207?), which are derived using a thermos-hydraulic process Simulation model (M1) and a structural-mechanical model (M2) of the process engineering apparatus (1).
