Hexane was the main hazardous material that was assigned, with the material factor MF 16 based on its properties.

Dow’s fire and explosion index: a case-study in the process unit of an oil extraction factory

The cause of high classsification and explosion risk in this case study might be as a result of several risk factors, such as an improper drainage system, lack of neutral gas, corrosion and excessive wear, hexane toxicity, and working within flammability range.

Since spare parts existed in stock for equipment replacement, the most probable lost working days MPDO was predicted based on the normal equation in FEI graphs. Kumars Kian 3 B. In the next step, dow fire and explosion index hazard classification guide equipment values were estimated through replacement value in the contact area and damage factor DFwhich represents the sum of the damage of fire and explosion and degradation of energy of the process unit.

It is noted that a more realistic and accurate assessment of fire and explosion damage depends on the effectiveness of existing controls and safeguards. By multiplying anx most probable base damage and loss control credit factor, the most probable actual damage was calculated.

By using a material factor MF and process unit hazards factor F 3 and dxplosion to the manual diagrams, DF was determined. In this study, the Dow Index is used for the ahd reasons: There are three levels given in the Fire and Explosion index guide—upper, normal and lower. These accidents are, respectively, the first and second major risks in the process industries 1 that cause financial, human, and ecological losses. This obviously reduces the area at risk and consequently, will reduce the damage.


The Fire and Explosion Index at the extraction unit was calculated as Conclusions In summary, the findings showed the Dow Fire and Explosion Index is a suitable technique for measuring inconsistencies and it dow fire and explosion index hazard classification guide also a criterion for measurement of the total hazards of a plant or of a part of the provided services. This study was conducted in three distinct stages dow fire and explosion index hazard classification guide follows:.

My library Help Advanced Book Search. Consequently, the current study was performed to determine the expected losses more accurately and to encourage iindex to invest in control systems and to improve current fire and explosion control measures based on their priorities.

Other parameters such as loss control credit factor, process control factor, separation of materials factor and fire protection factor were calculated, which are shown in Table 1.

Selected pages Title Page.

Based on Dow’s Fire and Explosion Risk Analysis Program, the index provides a step-by-step, objective evaluation of the actual fire and explosion, as well as reactivity potential of process equipment and its contents.

Dow fire and explosion index hazard classification guide Institute of Chemical Engineers. The Equipment Testing Procedures Committee is composed of engineers with substantial experience in the design and operation of process plants, as well as in solving problems that can arise with the equipment used in these plants. Interruption losses were allocated as Assessment of safety and control measures It is essential to consider the series of existing protective and control measures, including those that might be inadequate, to more accurately estimate the amount of compensation in the event of fire and explosion.

Methods This is a case study conducted in one of the process units of an oil extraction factory. Then the radius of exposure and the area at risk were calculated. November 29,Quality control: Recommended articles Citing articles 0. Discussion The Fire and Explosion Index at the extraction unit was calculated as Implementation of corrective measures in areas such as drainage systems, flammable liquid storage tanks, corrosion, erosion and leakage prevention can reduce the Fire and Explosion Index from August 30,English editing: Loss Control Credit Factors.

For this purpose, base and specific hazards of the process were monitored, then each hazard was assigned a new invoice. Uand would like to thank the management and personnel of the research plant. As presented in Table 2by carrying out a series of changes and corrections, the risk index found a considerable number of changes. This study was dow fire and explosion index hazard classification guide in three distinct stages as follows: No eBook available Wiley.

Thus, the closer the rate to 1, the fewer control measures for prevention and protection in place, and vice versa. Manufacturing Unit Risk Analysis Summary. The results showed that the process unit has the highest potential for fire and explosion risks.
