Understand API and ASME standards to prevent oversizing PSVs

Taylor, B., Anvil Corp.

If you have ever sized or selected a pressure safety relief valve (PSV) using vendor sizing programs or hand calculations, you have probably run into a strange anomaly.

Improve refinery production and efficiency with asset monitoring

Donnangelo, M., Emerson Automation Solutions

The sheer volume of equipment in a refinery—from vessels, columns, huge structures and mazes of pipes to pumps, valves, controllers and instruments—is staggering.

Built-up backpressure at the outlet flange of a pressure relief valve

Cordero, G. O., Techint Engineering & Construction

Even for pressure relief valves (PRVs) discharging directly to the atmosphere through short tailpipes, API 520 Part 11 warns that choked flow may develop at the outlet flange, resulting in high backpressure.

Stability analysis of debutanizer columns with hot-vap or bypass pressure control

Nagpal, S., IHS Markit

A debutanizer column was experiencing unstable operation, with frequent pressure swings and product composition fluctuations from the column overheads system.

Ensure a truly rigorous relief valve sizing method

Guner, U., Bryan Research & Engineering, Inc.

Pressure relief valves (PRVs) protect equipment from excessive overpressure and, in case of emergency situations, they should ensure a sufficient discharge of mass to reduce the pressure below the recommended pressure limits.
