Accidental release of hazardous chemicals

  1. Plume, Puff, Spill Dispersions with PROBITs based on Gaussian dispersion calculations and modeling, with tabular and graphic display with 6-User defined Isopleths in XY-Slice at Y-Cross wind distance. Full 3-D “CAT-Scan” output possible with dispersion “Cake slicing in XY (Isopleth)  Graphs. Graphics are in colour. It is a complete CAT-Scan with Probits (PROBIT short for Probability Unit, is the percent Fatality and Injury due to exposure to any hazardous agent.). This Advanced Dispersion provides for Mass and volumes of various concentration zones and concentration zone shells of Plumes, Puffs and Spill pool evaporation dispersions.

  2. Free spread Pool fire, Dyke Pool fire, Tank fire, jet fire, fireball, flash fire, with PROBITs. Graphics are in colour
  3. UVCE, BLEVE, Under ground explosions, mechanical explosions with PROBITs cylindrical vessel, spherical vessel, Dust explosion with PROBITs. Graphics are in colour. 
  4. ALARP, FAR, FN-Curve, ISO-Risk levels from 10-2 to 10-10, Individual Risk computations.

A QRA (Quantitative Risk Assessment) study is a systematic, data-driven process to quantify the probability and consequences of hazardous incidents in industrial settings, identifying potential failures, assessing their likelihood and impact on people, assets, and the environment. The steps involve hazard identification (like HAZID or HAZOP), scenario selection, frequency and consequence modeling, risk estimation, and implementing mitigation measures to achieve an Acceptable Level of Risk, often guided by the ALARP principle. 

1. Hazard Identification: Identifying potential sources of risk, often using techniques like HAZID (Hazard Identification) or HAZOP (Hazard and Operability Study). 
2. Scenario Identification: Generating a list of potential hazardous events and accident scenarios from the identified hazards. 
3. Frequency Analysis: Estimating the likelihood of each scenario occurring by using historical data, statistical models, and engineering principles. 
4. Consequence Modeling: Evaluating the potential impact and severity of the accidents identified, considering factors like toxic release, thermal radiation (fire), and blast overpressure. 
5. Risk Estimation: Combining the frequency and consequence data to quantify the overall risk in numerical terms, such as individual risk levels or societal risk. 
6. Risk Mitigation: Recommending and evaluating preventive and mitigative control measures to reduce the identified risks to an acceptable level, often aiming for ALARP (As Low As Reasonably Practicable). 

elp on how to do BLEVE simulations

 

BLEVE (Boiling Liquid Expanding Vapour Explosion) scenarios
A BLEVE is an explosion caused by a liquid, which is boiling and continuing to produce vapour.If the chemical is flammable, it is likely that the resulting cloud of the substance will ignite after the BLEVE has occurred, forming a fireball and possibly a fuel-air explosion. BLEVEs, which result in very large fireballs, occur when process vessels containing flammable materials with high vapour pressures are exposed to significant external heat. 

 

If Liquid is flammable flashing liquid or flammable liquid:

 

BLEVE scenarios

Under explosion scenario options

  1. Tank-over heating by external source or Mechanical Explosion leading to BLEVE scenario (CnE)  

  2. Tank-over heating by external source or Mechanical Explosion puff delayed internal ignition leading to Unconfined vapour cloud explosion BLEVE scenario (UCE)"

Under fire scenario options

  1. Tank over heating by external source puff Immediate Edge Ignition leading to Fire Ball leading to BLEVE scenario

 If Liquid is non-flammable

 

Mechanical Explosion scenario

Under explosion scenario options

  1. Tank-over heating by external source leading to Mechanical Explosion (CnE)
