Christian Liggett, Senior Engineer at Frazer-Nash Consultancy, will be presenting at Hazardex in the Regions: Grangemouth on 18 June. He will be exploring the DSEAR assessment for the Ammonia Synthesis Plant from Intermittent Renewable Energy (ASPIRE) project, a demonstrator facility for flexible E-Ammonia synthesis managed by STFC.

The ASPIRE project is funded under the Low Carbon Hydrogen Supply 2 competition supported by DESNZ.

Frazer-Nash supported the project through safety assessments at every major design phase: Preliminary Design/FEED, Detailed Design, and Commissioning. This staged approach enabled early integration of DSEAR expertise, ensuring safety considerations and best practice were embedded from the outset. The talk will highlight the advantages of this methodology and offer key insights into the specific hazards associated with E-Ammonia synthesis.

We’ll also delve into some of the safety arguments underpinning the DSEAR assessment, including the application of “Enhanced Tightness” and “Negligible Extent” concepts, as defined in BS EN 1127-1 and BS EN 60079-10-1 respectively. An overview of the Hazardous Area Classification (HAC) strategies for different sections of the plant will also be presented.
