Combining HAZOP with dynamic simulation—Applications for safety education

Automated HAZOP using hybrid discrete/continuous process models

“…The production of 2-octanone from 2-octanol in a semi-bach reactor was the example used by Eizenberg et al (2006) to illustrate the improvements of their quantitative HAZOP approach based on dynamic simulation. The reaction is carried out in a two phase medium: an aqueous nitric acid phase (B), the first to be loaded into the empty reactor, in contact with an organic liquid phase containing 2-octanol (A) that is added at a constant feed rate until a desired molar ratio of the reactants is reached.…”

Hazard and operability (HAZOP) analysis. A literature review

“…Lawley [8] defined and delineated the principles needed to carry out operability studies and hazard analysis due to the increasing complexity of new processes that could not be examined thoroughly using the then-conventional approaches based on equipment-oriented practices. Indeed, the requirement for having process-oriented methods [161][162][163][164][165][166] 3.6 of examination was the reason for the generation of HAZOP. Lawley's paper defines the planning, execution, and treatment of the operability study.…”

“…Eizenberg et al [163] introduced HAZOP into process-safety education, both for educational purposes and training operators. Combining HAZOP with dynamic simulation could offer students the means for exploring the consequences of emergencies.…”

Influence of parameter uncertainty on modeling of industrial ammonia reactor for safety and operability analysis

“…In last years, the model-based HAZOP approach has been developed (Dimitriadis, Hackenberg, Shah, &Pantelides, 1996, Graf andSchmidt-Traub (2001), Eizenberg, Shacham, and Brauner (2006) and Srinivasan, Dimitriadis, Shah, and Venkatasubramanian (1997)). It is based on the description of a chemical plant using a mathematical model.…”
