Relief devices are widely used means of overpressure protection within processing plants to protect against dangers of overpressure. Relief devices should be adequately sized for them to serve their purpose effectively. API Standards 520/521/2000 and ASME Section I/VIII list the design requirements for relief systems. Based on analysis done for over 60,000 relief devices worldwide for various types of operations consisting of refiners, petrochemical complexes, polymer processing and specialty chemicals, Ingenero uncovered numerous deficiencies within the exiting relief system design. Some of these deficiencies if left unattended can heavily compromise relief protection. This poster talks about common relief system design deficiencies and their root causes.
