API 521

This Guide presents recommended practices applicable to pressure-relieving and vapor depressuring systems. The information provided herein is designed to aid in the selection and type of system most appropriate for the risk and circumstances involved in the various installations. It is intended to supplement the practices set forth in API RP 520 for establishing a basis of design. 

Guidelines are provided for the examination of the principal causes of overpressure; for the determination of individual relieving rates; for selection of disposal systems; and for the design of disposal systems including such component parts as vessels, flares, and vent stacks. 

Piping information pertinent to pressure-relieving systems is presented in Sect. 5 Par. 5.3(A); however, the actual piping is to be designed in accordance with USAS B31.3 or other applicable codes.

API 521

This recommended practice is applicable to pressure-relieving and vapor depressuring systems. The information provided is designed to aid in the selection of the system that is most appropriate for the risks and circumstances involved in various installations. This recommended practice is intended to supplement the practices set forth in API Recommended Practice 520, Part I for establishing a basis of design.

This recommended practice provides guidelines for examining the principal causes of overpressure; determining individual relieving rates; and selecting and designing disposal systems, including such component pars as vessels, flares, and vent stacks. 

Piping information pertinent to pressure-relieving systems is presented in 5.4.1, but the actual piping should be designed in accordance with ASME B31.3 or other applicable codes.

Health risks may be associated with the operation of pressure-relieving equipment. The discussion of specific risks is outside the scope of this document.
