Which of the following is a common method to prevent over-pressurization in process systems?

Pressure relief systems are essential components designed specifically to prevent over-pressurization in process systems. These systems function by providing a safe outlet for excess pressure that may result from equipment failure, process fluctuations, or other unforeseen events. When pressure within a vessel reaches a predetermined limit, the pressure relief system activates, allowing gases or liquids to escape safely, thereby maintaining pressure within acceptable levels and protecting equipment, the facility, and personnel from potential hazards.

In contrast, flow restrictors can limit the flow of materials but do not directly address the issue of pressure build-up. Heat exchangers manage temperature control rather than pressure directly, while temperature sensors monitor conditions within a system but do not provide a mechanism for pressure relief. Thus, while all options may contribute to the overall safety and functionality of a process, pressure relief systems specifically target the prevention of over-pressurization.
