API Standard 521, Pressure-Relieving and Depressurizing Systems, provides guidance, recommendations, and alternatives for the design of pressure-relieving and vapor de-pressuring systems at liquefied natural gas terminals, petrochemical facilities, gas plants, and other petroleum production facilities.
API Standard 521, 7th Edition, provides guidelines for pressure-relieving and depressuring systems design. Engineering standard for oil and gas industry.
API 521 provides guidelines for flare sizing and relief conditions. This article explains core requirements, design implications, and more.
API 521 provides guidance for designing pressure relief and vapor depressuring systems across refineries, gas plants, LNG facilities, and petrochemical complexes. It helps engineers: Identify causes of overpressure — from blocked outlets to thermal expansion and external fires.
This API training course will focus on evaluating relief systems, applicability of overpressure scenarios, relief devices capacities and flare system calculations
API publications necessarily address problems of a general nature. With respect to particular circumstances, local, state, and federal laws and regulations should be reviewed.
RECOMMENDED PRACTICE 521 FOURTH EDITION, MARCH 1997 American Petroleum InstitutefFOREWORD This recommended practice has been developed as 2 guide for plant engineers in the design, installation, and operation of pressure-relieving and depressuring systems.
This document was produced under API standardization procedures that ensure appropriate notification and participation in the developmental process and is designated as an API standard.
An application programming interface (API) is a connection between computers or between computer programs. It is a type of software interface, offering a service to other pieces of software. [1] A document or standard that describes how to build such a connection or interface is called an API specification. A computer system that meets this standard is said to implement or expose an API.
