how do you design a relilef device

Question

Accepted Answer

A relief device is designed by considering the process conditions, fluid properties, and applicable codes and standards.

Identify the process conditions such as maximum allowable working pressure (MAWP) and temperature.
Determine the fluid properties including flow rate, density, and viscosity.
Select the appropriate relief device type based on the process conditions and fluid properties (e.g. pressure relief valve, rupture disk).
Calculate the required relieving capacity to protect the system from overpressure scenarios.
Ensure compliance with relevant codes and standards such as API 520, ASME Section VIII, and ISO 4126.
Consider installation and maintenance requirements for the relief device to ensure proper functioning.
Perform sizing calculations and simulations to validate the design.
Document the design process and specifications for future reference.
