Quantitative Risk Assessment (QRA) for DMAPA and Hydrogen Peroxide Tanks

  • Galaxy Chemicals Egypt Co. established a facility for manufacturing surfactants in Ataqa Public Free Zone, Suez.  The facility produced types of surfactants used for manufacturing home, personal care, and cosmetic products.  The company performed a Hazard and Operability (HAZOP) study that recommended a Quantitative Risk Assessment (QRA) to analyze the performance of the DMAPA tank, unloading line, and transfer piping system, in addition to the potential hazards from the hydrogen peroxide tank.  Environics was commissioned to conduct the QRA.
  • Environics carried out a QRA that aimed at identifying the potential risks associated with the processes of concern & the acceptability of their on-site/off-site risk exposure.
  • The main scope of the assessment was the acute, rather than chronic, hazards, being the potentially rare incidents that may result in fatalities or severe injuries. Document research and site visits were conducted to produce the assessment, which included the following:
    • Description of the storage tanks and the characteristics of the chemicals they contain and transfer
    • Description of the meteorological conditions in Ataqa area
    • Identification of the hazards and assessment of their frequency
    • Presentation of the potential hazardous scenarios
    • Discussion of the failure frequency and frequencies assessment
    • Modelling of the consequence scenarios to determine the potential impacts on the surrounding areas
    • Presentation of risk assessment
    • Recommendation of actions to reduce risks.
