Consequence Analysis

Consequence Analysis is a study based on events modeling for loss of containment of flammable or toxic substances that can lead to fire, explosions, or toxic leakage. It can be carried out at any point during the project’s development, from the initial design stage to when a hazard may present itself during operation. It is imperative that all asset owners are well informed on the potential impact of latent dangers within their facilities.

Pryxida TECH builds upon strong consequence analysis experience; we focus on intensively evaluating the repercussions related to thermal radiation, overpressure, and leakage of toxic substances. Our primary objective is to offer the highest possible quality information to our clients.

Software

Our team has a wide range of experience covering the use of specialized tools for the development of dispersion and impact models, such as:

Minimum Information Required

  • Process Flow Diagrams (PFD)
  • Process & Instrumentation Diagrams (P&ID)
  • Operating data and procedures
  • Mass and energy balances
  • Equipment datasheets
  • Process material composition

Process

According to previously identified hazards and the client’s requirements, Pryxida TECH establishes scenarios of interest to carry out the study. Each proposed scenario is modeled to determine if, under current process, material, and environmental conditions, the following events could develop:

  • Pool fires
  • Flash fires
  • Fireballs
  • Jet fires
  • BLEVE (Boiling Liquid Expanding Vapour Explosion)
  • Explosions
  • Toxic dispersion

It is key for us that our clients have a clear outlook on the studies conducted. We offer workshops to present findings and detailed explanations to clear up doubts, thus allowing for the asset owner to reach their project’s objectives.

Outcome

At the study’s conclusion, Pryxida TECH delivers a full-length report containing the following elements in detail:

  • First, the assumptions that were considered in the modeling process due to their criticality, with the results obtained
  •  Secondly, the graphic results of the events’ impact level layered over the plot plan with its respective analysis. Finally, we provide conclusions and recommendations to reduce the impact of the events.

We recommend the development of a QRA analysis to consider the failure frequencies and the probability of occurrence of these events. With this, the client’s decision-making process is based not only on consequence information.
