<p>Canada’s Oil Sands Region in northern Alberta contains the world’s largest deposits of commercially exploited bitumen. Extraction of synthetic crude oil from these deposits is a water intensive process, requiring large ponds for water recycling and/or final storage of tailings, already covering a total of over 100 km<sup>2</sup> of liquid surface area in the Athabasca Oil sands. The primary extraction tailings ponds primarily contain sand, silt, clay and unrecovered bitumen, while a few secondary extraction ponds also receive solvents and inorganic and organic by-products of the extraction process. Fugitive emissions of pollutants from these ponds to the atmosphere may therefore be a concern, but until recently, data on emission rates for many pollutants, other than a few reported under regulatory compliance monitoring, were sparse. We present here the results from a comprehensive field campaign to quantify the emissions from a secondary extraction pond to the atmosphere of 68 volatile organic compounds (VOCs), 22 polycyclic aromatic compounds (PACs), 8 reduced sulfur compounds as well as methane, carbon dioxide and ammonia. Three micrometeorological flux methods (eddy covariance, vertical gradients and inverse dispersion modeling) were evaluated for methane fluxes to ensure their mutual comparability. Methane and carbon dioxide fluxes were similar to previous results based on flux chamber measurements. Emission rates for 12 PACs, alkanes and aromatic VOCs, several sulfur species, and ammonia were found to be significant. PACs were dominated by methyl naphthalenes and phenanthrenes, while diethylsulfide and  and n-heptane were the dominant reduced sulfur and VOC species, respectively. The role of these previously unavailable emission rates in regional pollutant budgets will be discussed.</p>

Filtration Technology

Abstract The actual biotrickling filtration technology addresses volatile organic compounds (VOCs) removal from air, by their conversion into less harmful gaseous compounds (e.g. carbon dioxide). The actual study extends this capability towards not only VOCs removal, but also removal of carbon dioxide issued from biodegradation, in the same biotrickling filter (BTF). This upgrade results in higher C-capture and the reduction of greenhouses gases associated with this process, thus increasing the environmental performance of such BTFs. The model pollutant used in this study is ethanol, while a co-immobilised microalgae and compost-derived microorganisms is used for the first time accomplishing the above mentioned desiderate (simultaneously removal of VOC and carbon dioxide in the same BTF), under continuous regime and illumination provided by an array of light-emitting diodes (LED)). Very promising performances are obtained, revealing new competitive alternatives with high potential for further development, in the light of atmospheric protection and climate change issues.
