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 ...

Application of Hazard and Operability Analysis (HAZOP) Method for Risk Analysis in CGS Station [PDF]

Archives of Occupational Health, 2022
Background: The hazard and operability study (HAZOP) method is a risk assessment method based on engineering systems used for qualitative analysis or quantitative evaluation. It is mainly used to discover potential hazards and operational difficulties in

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.

How Can We Improve HAZOP, Our Old Work Horse, and Do More with Its Results? An Overview of Recent Developments

Chemical Engineering Transactions, 2016
All risk management starts in determining what can happen. Reliable predictive analysis is key. So, we perform process hazard analysis which should result in scenario identification and definition.

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 ...

Challenge pressure surge - which tasks have engineering and HAZOP?

Chemical Engineering Transactions, 2019
Pressure surges can damage pipeline systems and result in leakages which can cause considerable harm to people and the environment. Therefore it is a process safety topic directly related to the HAZOP.

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
