API Updates Gas Refinery Safety Standards


The American Petroleum Institute recently issued updated standards in the hopes of improving oil and gas refinery safety. The new initiative focuses on state of the art devices that help reduce pressure and increase safety.

New standards increase safety

According to Your Petrochemical News, the Sixth Edition of API Standard 520, Part II on Installation was published in March 2015 and aims to help managers of oil and gas refineries design and install pressure-relieving devices. It includes step-by-step instructions for industry professionals looking to make encouraged pressure adjustments.

“The standard offers engineering guidance for the design and installation of these critical safety devices which protect workers and the environment in the event of overpressure in process units and systems,” stated David Miller, API Director of Standards, in a press release.

Revisions made to old standards

In addition to this new standard, two older API standards were recently edited and revised. Your Petrochemical News explained that the Ninth Edition of API Standard 520, Sizing, Selection and Installation of Pressure-relieving Devices, Part I – Sizing and Selection, originally published in July 2014, was among the standards that underwent changes. The source explained that this previously-written rule referred to the selection and sizing of pressure-relieving devices. It provides managers with definitions and basic information about bringing pressure-relieving objects into their refineries.

One of the other standards that was recently updated by the API was The Sixth Edition of API Standard 521, Pressure-relieving and Depressuring Systems, which was originally published in January 2014. According to Your Petrochemical News, this standard discusses vapor depressuring systems, which it recommended for use primarily in oil refineries, though they can be used in liquefied natural gas facilities, oil and gas production facilities, gas plants and petrochemical facilities.
