Method for managing a process engineering facility

A method for managing a process engineering facility having at least one heat exchanger, wherein each of these heat exchangers is designed as a plate heat exchanger and each comprises a plurality of heat exchanger blocks, comprising:

• receiving sensor values from sensors which are arranged on or in the at least one heat exchanger;
• determining parameters wherein an operation of the at least one heat exchanger, on the basis of the received sensor values, wherein a temperature difference between heat exchanger blocks of the at least one heat exchanger is determined as a parameter;
• processing the sensor values and/or the parameters for a graphical display of a state of the at least one heat exchanger, wherein a service life of the at least one heat exchanger is determined as the state on the basis of the determined temperature difference between the heat exchanger blocks of the at least one heat exchanger, and a graphical display of the service life of the at least one heat exchanger is determined;
• outputting the processed sensor values and/or parameters in a graphical user interface, wherein the graphical display of the service life of the at least one heat exchanger is output in the graphical user interface;
• managing the operation of the at least one heat exchanger on the basis of the output, processed sensor values and/or parameters in the graphical user interface, wherein the service life of the at least one heat exchanger is monitored.
