To conduct a fire and explosion analysis (FEA) to: Assess the Hazer CDP flammable hazards and their potential consequences; Review the safeguards in place; and Identify additional measures to reduce or eliminate risks
Hydrogen and synthetic graphite producer
A commercial demonstration plant (CDP) that uses biogas produced at a waste-water treatment plant as the natural gas feedstock for the proprietary Hazer process that converts methane (in the presence of an iron ore catalyst) into hydrogen and synthetic graphite.
To bring awareness to any safety hazards and influence the necessary control measures, Add Energy’s safety and risk experts provided the client with:
Add Energy compiled their results, findings, and recommendations of the technical analysis within a detailed engineering report.
Our experts concluded that the loss of containment events at the CDP could result in various safety hazards. Below is a sample of our recommendations provided, designed to mitigate the hazards and impacts identified during the study:
Ensure ESD (isolation and blowdown) is automatically initiated (via the SIS) on confirmed fire/gas detection and the CDP shutdown philosophy is reviewed
Provide fire/gas detection in packaged equipment enclosures (e.g.,compressors/fuel cells). Confirmed fire/gas detection at the enclosures can then be aligned to the system ESD/pressurised hold shutdown levels.
Installation of an emergency gate on the northwest plant boundary to enable escape from the plant in the event that the main access gate or escape routes to the main access gate are impaired.
Assign a designated muster area >54m away from the process area (outside the 4.7kW/m2 thermal radiation isopleth and potential flammable gas cloud range).
Provide manual alarm call points throughout the site to allow site personnel to initiate ESD
Review the Hazer CDP gas detection arrangements to ensure an appropriate combination of catalytic bead (pellistor) type and ultrasonic detectors are provided. Relatively novel ‘thin-film’ hydrogen gas sensors should also be investigated.
Clarity of risks
Provided the client with clarity on the fire and explosion risks involved with the operation of the CD
Insight into all possible consequence
Defined the potential consequences of the fire and explosion events in terms of impact to personnel, escalation potential and impact to adjacent infrastructure
Actionable insights designed to mitigate risk
Offered clear recommendations of the ways to improve the safeguards and controls for the CDP
Expert opinion and assurance
Provided independent third-party analysis and advice for mitigating risk within 2 months
This study, and the subsequent actions were fundamental for assuring the project was sanctioned and all safety assurance measures had been identified
