HAZOP study teams must identify relevant parameters, i.e. those for which deviations could result in hazard scenarios within the study purpose, scope and objectives. This entails a systematic review of the process design. Some parameters usually are obvious. For example, flow, temperature, pressure and
Model-based HAZOP study of a real MTBE plant
In the presented paper, the model-based approach, including the HAZOP methodology, was applied on an methyl tertiary -butyl ether (MTBE) production plant. This case study is linked with a real industrial process and consists of two main operation units: a tubular reactor and a reactive distillation column.
Hazard and Operability (HAZOP) Studies
Background. A HAZOP study identifies hazards and operability problems. The concept involves investigating how the plant might deviate from the design intent. If, in the process of identifying problems during a HAZOP study, a solution becomes apparent, it is recorded as part of the HAZOP result; however, care must be taken to avoid trying to ...
What is HAZOP? Hazard and Operability Study | SafetyCulture
HAZOP, also known as HAZOP study or HAZOP analysis, is a Process Hazard Analysis (PHA) method recognized in OSHA's Process Safety Management (PSM) standard.
