CGA H-17, Guideline for Small Scale Hydrogen Production, addresses the safety aspects associated with siting and operating small scale hydrogen plants which are not currently addressed in existing publications for large HYCO (hydrogen, CO, and/or mixtures thereof) plants.
CGA G-4.1, Cleaning of Equipment for Oxygen Service, is a harmonized publication that describes the cleaning methods and requirements for equipment used in the production, storage, distribution, and use of liquid and gaseous oxygen in order to reduce the risk of fire, explosion, or promotion of combustion.
CGA recently issued a new publication CGA P-96, Reciprocating Cryogenic Pumps and Pump Installations for Hydrogen and Liquefied Natural Gas. The scope of CGA P-96 covers pumps in liquid hydrogen and liquefied natural gas, but this article will focus on cryogenic liquid hydrogen.
High temperature hydrogen attack is a mechanism that can significantly weaken and damage a variety of steel materials, including carbon steel and various low alloy steels, that are used in the construction of hydrogen plants. H-16 provides guidance for the review of existing plant assets, risk categorization, inspection strategies, and recommendations on risk mitigation, and actions for the owners and operators of HYCO plants in response to the updated guidance on the HTHA mechanism documented in API RP 941.
Over the last two years, CGA has worked to identify opportunities and develop a strategy for translating CGA publications into Spanish to facilitate adoption and acceptance in Mexico, Central America, and South America. In 2021, a task force of members was formed to evaluate the opportunities and strategy to translating a select group of publications to test demand and reach of the translations.
Compressed gas cylinders are used to store gases at high pressures. They can be dangerous if not handled properly, as they can explode or leak if damaged. Learn 10 tips for handling compressed gas cylinders safely.
In December 2022, the Compressed Gas Association released the 3rd edition of the harmonized publication CGA P-56, Cryogenic Vaporization Systems—Prevention of Brittle Fracture of Equipment and Piping. Learn more about this important harmonized standard in this publication spotlight.
CGA is modernizing the CGA Handbook of Compressed Gases by making it a virtual tool, and we are pleased to announce that the gas monographs are now available in electronic format and can be accessed by going to the Handbook publication detail page and then clicking on the “Handbook Online” button.
CGA’s Committees have been hard at work in 2022 and have published, revised, and reaffirmed more than 60 publications.
CGA has recently published a first edition publication P-97, Guideline for the Safe Handling of Liquefied Petroleum Gas Cylinders . Formerly known as S-8, this document dates back to 2007, when the first edition was issued with the title Recommendations to Minimize Hazards of CG-7 Pressure Relief Valves and Ancillary Devices for Liquefied Petroleum Gas Cylinders.
