Industrial pressure vessel design

The 1999 ASME Section VIII addenda reduced the standard design margin from 4.0 to 3.5, allowing for thinner steel walls in chemical plant equipment. Marcus and Sofia explain the engineering requirements for reactors, separators, and fractionators while detailing the 2010 Tesoro Anacortes refinery explosion caused by High-Temperature Hydrogen Attack. This analysis covers the transition from traditional half-life inspection rules to API 580 Risk-Based Inspection and the necessity of Canadian Registration Numbers for vessels operating in Alberta. Engineers use Finite Element Analysis in Level 3 Fitness-for-Service assessments to determine if distorted equipment remains safe for continued operat...
