Accidental LFG and LNG Release Modeling Application

BREEZE LFG Fire/Risk analyzes the potential risks associated with release of liquefied fuel gas (LFG) and liquefied natural gas (LNG) from a vessel or pipeline failure as required for regulatory compliance and safety operations. This product also enables the predication of the vaporization rate and downwind vapor concentrations for explosion hazards and thermal radiation for the resulting fires. LFG Fire/Risk contains Source5, DEGADIS, and fire models, as well as an intuitive interface that guides users through entering the required and optional inputs.

Product Tour

Source5 Model

Source5 is a LNG-specific model developed by the Gas Technology Institute that predicts the vaporization rate from instantaneous spills and continuous leaks over land or water. This model was developed to specifically handle the complicated behavior of LNG as it vaporizes and forms a dense cloud. With the Source5 model, users will have the ability to choose from a variety of release types when predicting the evaporation rate and spreading of an evaporating LNG release. Learn more

 

DEGADIS Model

DEGADIS is an EPA approved  dense-gas model that predicts downwind vapor concentrations for explosion  hazards, developed specifically to model heavier-than-air gaseous releases. A  cloud from a dense gas release behaves very differently than a plume from a  lighter-than-air release. Since the gas is heavier than air, the cloud  characteristics are primarily gravity-driven. Negative buoyancy and stable  density stratification are among the factors that prevent the application of a  Gaussian... Learn more

 

Fire Models

BREEZE LFG Fire/Risk provides users with four fire models to choose from for their model run; Confined Pool Fire, Unconfined Pool Fire, BLEVE, and Vertical Jet Fire. These fire models calculate the thermal radiation flux associated with a potential explosion and fire, as well as many other parameters, so users can efficiently analyze the potential risks associated with a specific scenario.Users have the ability to select between the four fire models by simply clicking the fire model icon on the...
