Course detail

Process Equipment Construction

FSI-9SPZAcad. year: 2022/2023

The course is focused on aging / lifetime control of process equipment in operational conditions. The content of the aging / lifetime management system and material damage processes is explained. Mathematical descriptions of the most common material damage mechanisms of process equipment such as fatigue, creep and corrosion are presented. Procedures for assessing the permissible growth of defects found by non-destructive methods and procedures for assessing the resistance of brittle fracture to process equipment are explained. The procedure of creating a process equipment damage scenario and selecting independent variables is explained, including the determination of their statistical distribution when calculating the probability of failure of pf and the risk of a major process equipment accident.

Learning outcomes of the course unit

A student will know that process equipment material damage while operating can be influenced and will learn the ways to influence it. The student will understand that only using mathematical description of material damage based on the experiments the level of material damage and residual lifetime can be found. The students will learn that methods available now are to be constantly developed. They will be introduced to the scope and type of input data for the calculations and purposefulness of their statistical distribution knowledge. The students will know the difference between deterministic way of analysis and probabilistic analysis of accident occurrence.
