HAZOP and Preliminary Process Safety Considerations on an e-SMR for Hydrogen Production

The demand for hydrogen is increasing rapidly, yet the current production process via methane steam reforming is responsible for a staggering 3% of global dioxide emissions. To tackle this issue, innovative production processes such as those based on renewable energy sources, biomass, and carbon capture, usage, and storage (CCUS) technologies are being explored. One highly promising solution is the electrification of the methane steam reformer, which can significantly reduce carbon dioxide emissions. To ensure maximum safety and minimize risks, the widely adopted Hazard and Operability (HAZOP) approach is implemented in the risk assessment of a new chemical plant startup that produces pure hydrogen from biogas, with CCUS strategies in place. The electrified catalytic reformer achieves almost complete methane conversion. The Hazop analysis helps to detect potential risks, hazards, and operational issues, providing a comprehensive understanding and recommendations to mitigate and eliminate the identified risks. Additionally, analyzing the process in terms of compatibility matrix supports the identification of preliminary process safety considerations. Overall, the goal is to ensure maximum safety and minimize risks throughout the production process.
