Application of innovative risk assessment methodology for damage mechanisms identification on part of amine regeneration unit

When implementing the method for quantitative risk analysis, usually based on RBI (Risk Based Inspection), conditions which directly influence the identification of damage mechanisms are defined at the beginning of the analysis. Thus, conducted analysis applies to the exact parameters and very specific combinations of conditions and damage mechanisms. The question arises as to whether such an analysis and its results may represent initial data for some subsequent analysis that can be carried out in the following period, regardless of the reasons for the implementation. The extension of the methodology from the one shown in the ASME PCC 3 standard is to identify both active and passive/potential damage mechanisms and the conditions under which passive can be activated. This addition to the methodology is successfully applied in case of a Middle East refinery, and as a representative example, a typical amine regeneration unit present in all modern gas or oil refineries, specifically the ...part of the unit with lean amine, is shown.
