A Bayesian Approach for Estimating the Thinning Corrosion Rate of Steel Heat Exchanger in Hydrodesulfurization Plants

Parameter Distribution for (a) Location, (b) Scale, and (c) Shape parameters of the GEV model for wall thickness thinning rate in heat exchangers (all the Probability Density Function (PDF) values plotted in this paper were adjusted in order for the distribution to “look like” the histogram. To do this, it is necessary to convert the PDF to the histogram’s size using the bins’ width and the number of bins. Reference [44] explains this process in detail).
