Abstract
In the presented paper two quality parameters are used to represent the state of a heat exchanger.
The remaining lifetime can be estimated by trend regression. Also of interest is the uncertainty of the
predicted lifetime which is determined by the confidence interval of the parameter estimation. These
algorithms developed are used in this paper in an off-line evaluation of the measurements on a heat
exchanger in a refinery. It is shown that the time point of the heat exchanger cleaning can be predicted. So
the presented method can be used for planning the cleaning time point in advance and saving money in
maintenance.
