Resumo: | |||||||||||||||||
The present work presents studies related to the simulation
of transport and attenuation processes of gasoline spills
in conditions normally encountered in petrol stations. These
studies are carried out through the application of
numerical methods for the analysis of transport of
multicomponents in porous media.
Computer programs for 3D analysis of flow and transport of
contaminants were used as well as graphics routines for the
visualization of results. A detailed study of the programs
used was carried out. Validation tests were performed as
well as an external implementation of a new routine to
simulate a particular chemical reaction (reaction of BTEX
with Fenton`s reagent) related to a special remediation
technique.
As application of the studied procedures, a case related to
the gasoline spill in a petrol station located in the city
of Rio de Janeiro-RJ was focused. In order to represent as
close as possible the gasoline spill the simulation was
divided into three stages. The first one, refers to an
attempt to reproduce the flow and contamination conditions
of BTEX compounds formed in situ until the removal of the
underground tanks. The second stage corresponds to a period
just after the replacement of the damaged tanks. Finally,
the last stage consisted in the injection of oxygen used
for bioremediation of the contaminated area.
The present work describes the overall methodology used,
the obtained results and pertinent comments.
