Selection of safety valves for natural gas buffer tanks
Thread Content
The most important parameters for selecting a safety valve are the set pressure and discharge capacity. I need to install a safety valve on the buffer tank; should this set pressure be determined by multiplying the normal operating pressure by a safety factor, or should it be based on the design pressure? As for the discharge capacity, I think it’s sufficient as long as the safety valve can expel the gas when it opens in order to reduce pressure. Increasing the discharge capacity is intended to help lower the pressure in the tank more quickly. Are there any relevant standards or formulas for calculating the discharge capacity? Thank you in advance to all those with experience in this field.

Is there any requirement regarding displacement due to overpressure in the buffer tank, or are there specifications for the size of the safety valve’s interface during the design process? Since the pressure inside the buffer tank changes with the volume of gas, how should the pressure and displacement of the safety valve be determined? Thank you everyone; I’m a newcomer and seeking guidance
