Integrity and life assessment of catalytic reformer units

To summarise, therefore, this chapter is structured on a major component basis and the differential timeframe assessment approaches that can be made to these in the various types of CRU. 

1 Model types for timeframes and major components. Condition is as determined by inspection. 

Confirmation of current integrity status and definition of the probability and consequence of failure are essential plant management requirements. The following sections of this chapter deal with the approaches that can be made, both during the production period and at shutdown by utilising plant assessment technology to provide this information. Previous reviews (Brear, 1997 Brear and Townsend, 1997) have detailed the individual assessment techniques and the overall phased approach to component life assessment. 

Within the refining industry, the risk-based inspection procedure put forward by the American Petroleum Institute in its Recommended Practices RP-580 (2000) and RP-581 (2000) has been generally adopted and its three levels can be summarised as follows  

Qualitative analysis of a process unit is the starting point for any plant- or unit-wide risk based inspection study. It can be carried out while the equipment is in operation and comprises four main steps. To ensure uniformity of treatment and coverage of all aspects, a formal workbook or appropriate software is used to identify, record and analyse the necessary data.
