Terrain Modelling Effects on Risk Contours for a Liquid Biogas (LBG) Plant

The effects of terrain modelling on risk contours for a Liquid Biogas (LBG) plant

This case study highlights the importance of correct terrain modelling when assessing risk related to a Liquid Biogas (LBG) plant in a hilly area.

VEAS, Norway’s largest wastewater treatment plant, is setting out to produce LBG for carbon-neutral public transportation in the Oslo area.

Gexcon has assisted VEAS in assessing the risk and establishing a risk analysis for approval by the Norwegian Directorate for Civil Protection (DSB).

 

What you will learn

In this case study, you will learn:

  • Terrain has a significant influence on the dispersion of flammable gas
  • Terrain effects can be realistically modelled using CFD
  • Realistic modelling of dispersion improves the understanding of risk and gives better decision support for a cost-effective plant design and operation
  • 3D risk contours can be calculated and presented in a realistic terrain model using FLACS-CFD
