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.
