SUSTAINABILITY
Air Quality Protection
Eni is committed to implement the best available techniques and the best procedure standards for the reduction of emissions and the control of main pollutants (e.g. nitrous oxides, sulphur oxides, particulate, carbon monoxide and aromatics). In addition, following the issues of the of integrated environmental authorizations, some plants located in sensitive areas applied measures to control and contain dusts and their precursors, as well as smelling emissions.
The 2010 has been considered a restart of activities recording a CO2 emission from combustion and consumption increase compared to 2009 which was affected by the economic crisis during 2008. SO2 emissions have recorded a total increase of 4.8%. The performance is attributed to the refining sector temporary closure of desulphurization and denitrification (SNOx) plant of the Gela refinery in addition to the start up plants of Taranto refinery. Nonetheless, it is important to highlights the significant SO2 emission reductions following the fuel switching of various sectors: G&P (down 21%), E&C (down 24%) with a fuel reduction (ATZ down 96% and BTZ down 73%) and Petrochemical sector (down 28%) with a 32% of BTZ reduction.
In 2010, NOx emissions declined by about 5.4%. This trend is mainly attributed to the contribution of the E&P sector (reduction of 8.5% corresponding to about 6,396 tonnes) that balances the 7% increase in the power generation (emission indexes hold steady).
In 2010, Eni implemented or improved the monitoring of air quality in some affiliates in the E&P sector in Angola, Croatia, Indonesia, Italy, Kazakhstan, Libya. EniPower completed the installation of VeLoNOx burners on 8 combined cycle plants of the 9 that are technologically suited to this technology. The Petrochemical sector continued the monitoring of fugitive emissions that was started in 2009. At year end, 265,000 units were set up for monitoring these emissions. The project will be completed in 2014. In the area of transport and storage, Eni continued to substitute old turbines with new ones with lower emissions, in the next 4 years other 13 turbines will be substituted.
In the second half of 2010, Eni started a pilot project called "Development of a VOC monitoring system" based on the Wireless Sensor Network technology at the Mantova plant. This project aims at identifying possible measures for reducing environmental impacts, it involves business units taking part in drafting a unified standard.
