USE OF THE HAZOP ANALYSIS FOR EVALUATION OF CVD REACTORS [PDF]

Le Journal de Physique IV, 1991
Before equipment is installed at AT&T Bell Laboratories, Allentown, a hazard and operability (HAZOP) analysis is done. Through a systematic process, a team leader guides a group of knowledgeable individuals through the equipment design to discover the hazards and the operating range of the equipment.

From continuous to interruptible distillation: Flexible electric heating column architecture with fast start‐up

AIChE Journal, Volume 72, Issue 8, August 2026.
Abstract Electrification of distillation offers a promising route to reducing scope‐1 emissions from one of the chemical industry's most energy‐intensive unit operations. However, conventional adiabatic columns are dynamically inflexible: Long, energy‐intensive start‐ups make shutdown and restart impractical under variable electricity prices and ...

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 ...
