Several measures are taken in an LNG plant to prevent overpressure events, which are critical to ensure safety and prevent equipment damage. Pressure safety valves (PSVs) are installed on equipment and pipelines to automatically relieve pressure if it exceeds a safe limit. These valves are designed to open at a set pressure and vent the excess pressure to a flare system or a safe location. Pressure indicators and controllers are used to continuously monitor and control the pressure in process equipment. These devices provide operators with real-time information about pressure levels and....
