HAZOP Study of Process Plants Covered under IREP #CDU/VDU3, DHDT, VGO HDT, PFCC, DCU, SRU3 & related utilities for Kochi refinery - BPCL

Bharat Petroleum Corporation Limited awarded iFluids Engineering to conduct the Hazard and operability study (HAZOP) for the following Process Plants: CDU/VDU3, DHDT, VGO HDT, PFCC, DCU, SRU3, NHT-ISOM and related Utilities.

HAZOP, the concise form of Hazard and Operability Study is a systematic way to identify the hazards associated in a process. Firstly, the study begins by breaking down the process into simple nodes and uses guidewords (No, Less, More) combined with the significant process parameters (Flow, Temperature, Pressure & Level) to form Deviations. Deviations helps us to brainstorm the causes for the particular deviation happens in the process. For Example: In a particular node, what are the causes for No flow. Then, it identifies the consequences and their safeguards present in the system for each cause. After that, it evaluates the sufficiency of the existing safeguards and access whether those safeguards are adequate enough to protect PEAR (People, Environment, Asset and Reputation) related to the system. Finally, if the safeguards are not enough to protect PEAR, feasible recommendation/s would be proposed. Thus, the same process is repeated step by step for all the nodes.

BPCL HAZOP had been successfully completed by brainstorming each unit with the multi-disciplinary team such as process engineers, DCS engineer, Process safety Engineer and Control & Instrumentation engineers led by the Chairman. Therefore, BPCL HAZOP quantitatively evaluated the severity and risk for each consequence and identified the gaps present in the process with the aid of above mentioned procedure.
