A Computational Study of the Implosion of a Food Storage Tank

Chemical Engineering &Technology, Volume 49, Issue 8, August 2026.
This study focused on a structural and thermodynamic analysis of a real‐case implosion incident of a storage tank after a cleaning procedure in a food industry company. A quantitative analysis of the incident will support future studies of solutions to prevent it.

Chemical Risk Assessment in Black Mass Processing Facilities: Addressing Safety in a Critical and Emerging Industry

Advanced Energy and Sustainability Research, Volume 7, Issue 7, July 2026.
A dedicated chemical risk assessment framework for black mass processing across different operational scenarios is proposed. By integrating regulatory hazard classification with a semi‐quantitative probability–severity matrix, the framework provides the first structured tool for risk evaluation and prioritization in black mass facilities, supporting ...

Stream-based HAZOP: A More Effective HAZOP Method

, 2011
The Hazard and Operability Study (HAZOP) is probably the most commonly applied process hazard analysis method. As such, HAZOPs are a very important tool for improvement of process safety. But HAZOPs are not as effective as they should be.

AI in chemical engineering: From promise to practice

AIChE Journal, Volume 72, Issue 7, July 2026.
Abstract Artificial intelligence (AI) in chemical engineering has moved from promise to practice: physics‐aware (gray‐box) models are gaining traction, reinforcement learning complements model predictive control (MPC), and generative AI powers documentation, digitization, and safety workflows.

Multi‐Criteria Decision‐Making Methodologies Applied to Hazard and Operability Studies in High‐Hazard Industries

Quality and Reliability Engineering International, Volume 42, Issue 2, Page 774-792, March 2026.
ABSTRACT Major accidents causing fatalities and significant environmental and asset damage continue to occur in high‐hazard industries, despite regulatory requirements and organisational mitigation measures. The Hazard and Operability (HAZOP) study is a widely used risk assessment method to identify hazards and implement mitigation measures, but it has

Meta‐Analysis of Industry Incident Reports: Identifying Gaps in Climate‐Related Safety Risks

Safety Science and Technology, Volume 1, Issue 1, March 2026.
Climate‐related hazards like floods, storms, and heatwaves are increasing, raising concerns for industrial safety. When such events trigger technological failures (NATECH incidents), consequences can be severe, particularly in chemical and energy sectors. A PRISMA and bowtie‐based meta‐analysis of 50 climate‐linked incidents from the US Chemical Safety
