What is the purpose of using pressure relief devices in compression equipment?

The purpose of using pressure relief devices in compression equipment is to ensure safety by limiting each stage's pressure to the maximum allowable working pressure. Compression systems operate under significant pressure, and without adequate safety mechanisms, there is a risk of equipment failure, which can lead to hazardous situations including explosions or catastrophic failures.

Pressure relief devices act as safety valves that open to release excess pressure, effectively preventing the system from exceeding the set safety limits. By maintaining the pressure within safe boundaries, these devices protect not only the equipment and its operators but also reduce the risk of environmental harm. This is crucial in industries using compressed natural gas, where the handling and compression of gases present unique safety challenges.
