As part of initiatives to mitigate environmental impact, during 2010 INA completed the process of introduction of Euro V fuel at its petrol stations. New products, Eurosuper 95 BS and Eurodiesel BS, are high-quality fuels containing up to 10 mg/kg of sulfur, and fully meet the European standards EN 228 and EN 590.
CO2 emissionsIn the year 2010 INA, d.d. facilities emitted 12.02% less CO
2 than in the previous year due to reduced primary and secondary production, and lower heating value of refinery gas (until 2010 literature data were used for emission factor, and in 2010, in accordance with the Greenhouse Gases Monitoring Plan, the emission factor calculation was based on gas analysis). Carbon dioxide emissions derive from process plants, steam and power production plants and boilers used for heating the facilities.
In 2011, 3.2 % less CO2 was released from INA facilities in comparison to previous year. INA’s total CO2 emissions (direct + indirect) in 2011 amounted to 2,098,071.45 tones.
CO2 emissions from INA, d.d. in the last five years and INA Group in 2010
CO2 emission reduction measuresDuring the year 2010 through newly built pipeline Kukuljanovo – Urinj natural gas has reached Rijeka refinery and is used for running newly built installations (hydrogen production plant, hydrockrecking). Installation of the natural gas pressure release station in Refinery Rijeka is in progress, with the aim of bringing natural gas as fuel to all process furnaces and boilers.
CO
2 emissions trading (EU ETS): In addition to the Regulation on Greenhouse Gas Emission Quotas and the Method of Emission Allowance Trading the greenhouse gas emission monitoring were made plans for INA Group instalations (Rijeka and Sisak refinery, CGS Molve, Etan plant, Zagreb Lubricants), which will be covered by the emission trading scheme (ETS).
Since January 1st 2010 CO
2 emissions have been monitored in accordance with GHG emission monitoring plans, and after Croatian accession to the EU, but not before January 1st 2013, these plants will become a part of the European emission trading scheme (EU ETS).
In July 2011, an installation for releasing natural gas pressure was installed at Rijeka Refinery, making possible the supply of natural gas as an energy source for boilers and process furnaces and its continued use. This resulted in reduced SO2 emissions (by 31.5%) in 2011 compared to 2010, while the number of SO2 emission limit transgressions at the refinery’s air quality monitoring station was reduced as well.
The EOR (Enhanced Oil Recovery) project in Exploration & Production BD aimed at increasing the oil recovery by CO2 injection is in the final stage. Injections are planned on the Ivanić and Žutica fields, the carbon dioxide source is Central Gas Station (CGS) Molve in the Podravina District. The project has an environmental dimension, as it imprinted significant amounts of CO2 into the underground thus reducing emissions into the air.
