Environmental and social <strong>responsibility</strong> / Calculation of emissions According to guidelines, fuel combusting facilities may only use measured fuel streams whose emission characteristics are known. Fuel consumption is measured with the help of measuring systems used to measure the size of fuel consumption and subject to adjustment and control. Fuel consumption in <strong>PKN</strong> ORLEN is continuously balanced, based on measuring circuits installed at fuel feeders. Calorific value is calculated on the basis of gas composition specified with the application of chromatographic analysis method. Sampling frequency is determined by analyses schedule developed on the basis of required sampling frequency. Analyses are performed by a laboratory possessing required accreditations. Emission indicator is calculated on the basis of chromatographic analysis of composition. In 2009, we <strong>report</strong>ed an approx. 0.5% drop in total emissions to the atmosphere compared to the previous year, while the volume of processed oil went up by over 2%. The drop in total emissions was accompanied by increased emissions from energy generation such as: SO 2 , NOx and CO, while the emissions of hydrocarbon and dust dropped. The drop in total hydrocarbons by 10% was caused by the permanent shutdown of the Ethylene Oxide and Glycol I unit, while dust emission fell by approx. 12%. This is due to lower ash content in fuel combusted in the Plant’s process boilers and furnaces, compared to 2008. Increased emission of carbon monoxide resulted from a large load of post-combustion furnaces at the Hydrosulfreen unit and changeability of composition of post-combusted chimney gas and fuel gas, which resulted in variable oxygen demand. The increased emission of this pollutant remained within the limits specified in the integrated permit. Pollutant emission was continuously measured at three emitters at the CHP. Their scope covered: SO 2 , NOx (NO 2 ), dust. Periodic measurements of pollutant emission: • in 2009, we performed 92 checks of pollutant emission at emitters at the Production Plant in Płock, including 54 emitters subject to mandatory measuring; • emission measurements were carried out at emitters included in the integrated permit twice a year, once in each half-year; • the scope of periodic emission measurements covered (depending on the emitter) the following pollutants: SO 2 , NO 2 , NOx (NO 2 ), CO, dust, H 2 S, aliphatic hydrocarbons, aromatic hydrocarbons: benzene, toluene, xylene, cumene.
