Resumo
The Brazilian CO2 Pilot Project was started off in 2012 in Florianopolis, SC, at a
6,280 m2
experimental cell located at the Ressacada Farm, Santa Catarina
Federal University (UFSC), fully sponsored by PETROBRAS Research Center
(CENPES). This pioneer initiative was carried out as a technical cooperation
among CENPES, the Brazilian Academy and international researchers, to
provide field infrastructure for carbon dioxide simultaneous detection in the open
environment, encompassing the atmosphere, subsurface and soil. The project
goals are to deploy, test and assess the multiple measurement tools
simultaneously deployed on site during CO2 controlled releases. These
methodologies are likely to be applied in future large scale carbon sequestration
sites. This work presents the initial results of the atmospheric dispersion
modeling studies and an overview of the atmospheric measurements carried out
in the 2013 CO2 controlled release, in which a standard CO2 Eddy Covariance
System (ECS) and a CO2 (delta13C) Isotope Gas Analyser (IGA) were deployed
to track CO2 in the air. Dispersion studies, currently at an early stage, were
carried out using AERMOD 8.8.9. Results showed overall consistent trends,
when comparing the outcome from the monitoring set as well as when
confronting model output with experimental data.
Keywords: geological carbon sequestration, CO2 controlled release,
atmospheric dispersion modelling, Eddy covariance, isotopic measures.
