IGEM/SR/25 Hydrogen Supplement - Hazardous area classification of installations using Hydrogen or blends of up to 20% by volume Hydrogen in Natural Gas

A draft of IGEM/SR/25 Hydrogen Supplement - Hazardous area classification of installations using Hydrogen or blends of up to 20% by volume Hydrogen in Natural Gas, is available for comment.

A draft of IGEM/SR/25 Hydrogen Supplement “Hazardous area classification of installations using Hydrogen or blends of up to 20% by volume Hydrogen in Natural Gas”, is available for comment. This draft Standard has been prepared by a Panel and is submitted to industry for its consideration and comment. The draft can be found here and the comment form can be downloaded here.

Background

This supplement to the standard IGEM/SR/25 Edition 2 presents the data and approaches needed to perform hazardous area classification for installations handling hydrogen, including blends of up to 20% hydrogen by volume in natural gas. The supplement contains updated tables of zone distances for fixtures and fittings, and vent pipe terminations for both pure hydrogen and for blended gas. The principal topics covered in the supplement include the calculation of gas mass flow rates, an updated approach for estimating failure frequencies for equipment where hydrogen is present and a calculation procedure for assessing the adequacy of ventilation for enclosures in which a hydrogen or blend release may occur. The supplement is written to be used in parallel with the existing version of IGEM/SR/25.
