What is the primary function of a pressure relief device in CNG systems?

To hold maximum pressure indefinitely
To vent excess pressure to the atmosphere
To enhance fuel efficiency in combustion
To reduce the temperature of the gas

The correct answer is: To vent excess pressure to the atmosphere

The primary function of a pressure relief device in CNG systems is to vent excess pressure to the atmosphere. This is crucial for maintaining safe operating conditions. In cases where the pressure within the system exceeds safe levels, the pressure relief device activates to release gas, preventing potential failure or rupture of the system components. By allowing excess pressure to escape, the device helps to ensure the integrity of the storage tanks and other system components, thus protecting both the equipment and the environment. This safety feature is essential in any gas system, particularly one involving high-pressure gases like compressed natural gas, where maintaining appropriate pressure levels is vital to prevent accidents or hazardous situations.
