Abstract
A numerical study of heavy gas dispersion over sea from an LNG storage facility
at Renythousa Island in Greece is examined for the various hazards imposed on
the population of the surrounding areas. The study is done by using the code
ADREA-HF solving the conservation equations of mass, momentum and energy
for the mixture of the heavy gas and air, as well as the mass fraction of heavy
gas. Distributions of methane, ethane and propane concentrations for various
time instants after the gas release are obtained, identifying the riskiest zones
using scenarios based on weather forecast data. Thus the contribution of this
work is to show how the available time for the authorities to safely evacuate the
nearest affected areas can be evaluated.
Keywords: heavy gas dispersion, Navier-Stokes equations, turbulence model,
flammable plume zone.
1 Introduction
Large quantities of substances that are hazardous for the public and for the
environment are produced or utilized in large quantities by most modern process
industries that are often sited near populated areas. These substances being
toxic, radioactive, flammable or explosive during an accident in the production
process, transportation or storage may provoke a release of gas (or gas-liquid)
clouds or plumes that are denser than air. The density difference of the
formulated \“heavy gas” introduces buoyant forces that can distort significantly
Keywords
heavy gas dispersion, Navier-Stokes equations, turbulence model,
flammable plume zone.
