“…At each of these nodes, deviations in the process parameters are examined using the guide words (Dunj o et al, 2011a(Dunj o et al, , 2011b). To perform this task, the main causes that produce the performance deviations (i.e., failures or human errors), identified in step 2, can be easily used and added to the HAZOP worksheets (Fig.…”

“…Substance cycles and establishments are by and large combustible, hazardous and harmful. In this manner, the distinguishing proof of these risks is fundamental to guarantee the protected plan and activity of these handling plants [4]. The number of procedures created to forestall mishaps in process ventures has expanded since the modern upheaval.…”

The HAZOP strategy is viewed as one of the best peril investigation methods and was created with the central point of giving a standard danger decrease process pointed toward guaranteeing the wellbeing and operability of exercises. Guarantee the creation of the unit. This study means to apply the HAZOP strategy to process and security activities in the petrol creation industry. Raw petroleum creation units are isolated into more modest segments and investigates are performed on these segments. By applying the HAZOP technique, the probabilities of 71 related not set in stone. Assessments of ecological, wellbeing and financial effects focus on their preservation. The utilization of the technique and the preventive activities characterized brought about 47 suggestions to address the issues distinguished.

“…The HAZOP methodology was developed in the 1970s, when the growing size of chemical plants made a preventive approach necessary. In subsequent years, this methodology was applied to pharmaceutical [12], nuclear [13] and transportation [14] sectors and in continuous chemical processes [15,16].…”

Hazop Analysis of a Bioprocess for Polyhydroxyalkanoate (PHA) Production from Organic Waste: Part A

et al. 2023

View full text Add to dashboard Cite

the number of bioprocesses for the circular economy of organic waste has grown in recent years. Implementation of new processes and technologies should consider occupational health and safety issues from the initial design stages. Among the process hazards analysis techniques, HAZard and OPerability (HAZOP) methodology is widely used for studying both the process’s hazards and their operability problems, by exploring the effects of any deviations from design conditions. In the present study, a modified version of HAZOP methodology has been applied to a three-steps process developed at pilot scale in the Treviso municipal wastewater treatment plant in order to produce polyhydroxyalkanoate (PHA) as the final high value product. This paper shows the results of HAZOP analysis applied to the first process step (acidogenic fermentation) aimed at volatile fatty acids production. The analysis has been applied to the process conditions corresponding to the maximum PHA content in the biomass. The HAZOP study results showed that this methodology allowed a comprehensive exploration of conventional chemical engineering process hazards and biological hazards. Final piping and instrumentation diagrams (P&IDs) for acidogenic fermentation have been designed, identifying all prevention measures aimed at managing the hazard and operability issues. The P&ID shows the interconnection of equipment and the instrumentation required for controlling the process.
