The inlet pressure drop rule is designed to protect pressure relief valves (PRVs) from instability; however, recent changes to API 520 allow the pressure drop to go above 3% of the set pressure if a supplementary engineering analysis is completed. This article, published in the September 2021 issue of World Fertilizer, discusses the improvements to the API codes and standards and how those changes impact the 3% rule.

Combustible dust explosions are well-documented, well-studied, and entirely preventable, and yet they continue to claim lives, as tragically demonstrated by the July 2025 explosion at a Nebraska biofuels facility. This article introduces the engineering fundamentals of explosion venting, walking through the key parameters, calculations, and judgment calls required to design a compliant and effective deflagration vent per NFPA 68.
Fragmented in-house knowledge and overreliance on third-party expertise are quietly eroding process design capability across the industry. Equity’s Process Design Practices (PDPs) provide a structured, customizable framework for capturing and transferring process design knowledge, supporting everything from equipment sizing and fluid handling to safety systems and basic engineering reviews.
Codes and standards are referenced constantly in process facilities, but early-career engineers often lack a clear framework for understanding what they are, how they relate to each other, and why they carry real legal and safety consequences. This article in our Engineering 101 series provides a practical introduction to the codes and standards landscape, covering construction codes, in-service codes, FFS standards, and RAGAGEP, with field examples and common pitfalls to help new engineers build a working foundation, whatever their role.
When a heat exchanger tube ruptures, the consequences can extend far beyond overpressure, as uncontrolled mixing of incompatible fluids can create serious safety, environmental, and operational risks that demand rigorous engineering assessment. This article examines the tube rupture credibility assessment (TRCA) and the critical role that damage mechanism review plays in determining whether a full-bore tube rupture is credible, and what that conclusion means for relief system design and inspection planning.
