This paper provides a detailed examination of API Standard 521, the industry benchmark for the design and sizing of pressure-relieving and depressuring systems. As the downstream oil and gas industry operates under high pressures and temperatures, the integrity of process equipment relies heavily on Overpressure Protection (OP) systems. This document explores the fundamental causes of overpressure, the methodologies for calculating required relief rates, and the sizing criteria for relief devices. Furthermore, it addresses the increasing industry focus on Depressuring Systems, flare network dynamics, and the integration of API 521 with API 520 and API 526. This paper serves as a technical guide for process engineers regarding the safe and compliant design of safety systems.
