The accumulation during the relief process in a vessel specifically refers to the pressure increase over the Maximum Allowable Working Pressure (MAWP) of the vessel. This concept is crucial in understanding pressure relief systems, as they are designed to engage and function when the pressure within the vessel exceeds its safe operating limits. The relief device, such as a pressure relief valve, acts to prevent a hazardous situation by allowing excess pressure to escape, thereby protecting the integrity of the vessel and ensuring safety.

When discussing accumulation, it's important to note that it is a key factor that must be taken into account when designing and maintaining pressure vessels, as excessive pressure can lead to catastrophic equipment failures. Understanding how accumulation operates allows safety engineers and operators to implement appropriate safety measures and ensure compliance with safety regulations. This knowledge is critical for anyone involved in the operation or maintenance of pressurized systems.
