Emissions

Air emissions are created when products of human activity (substances which may have a negative impact on the environment in high concentrations) are introduced to the atmosphere. Air protection is basically the reduction of such emissions through upgrades of existing industrial technologies and investments in environmentally friendly transport.

In an effort to limit air emissions, PKN ORLEN monitors the conditions of their release into the atmosphere. We carry out air measurements on an ongoing and periodic basis, monitor air quality around the Płock Production Plant, and oversee the management of greenhouse gas emissions. This allows us to collect information on the environmental impact of our operations, and to assess the efficiency of measures implemented to protect the environment.

Air emissions

The 2014 results of periodic measurements of air emissions from the petrochemical, refining and CHP units in Płock and the PTA Plant in Włocławek confirmed that neither plant exceeds the permitted levels defined in integrated permits. The data from the continuous emissions monitoring system installed at the emission sources in the on-site CHP plant were in line with the Minister of Environment’s Regulation on Emission Standards for Installations.

Lower nitrogen oxides emissions in 2014 were attributable to the construction of new SCR units on K5 and K6 boilers, whereas higher sulfur dioxide emissions were caused by a 23% year-on-year decrease in gas consumption at the CHP plant, as well as an emergency shutdown of the circulating gas compressor at the petroleum tar desulfhurisation unit, which led to reduced supply of low-sulfur fuel for the CHP plant. Lower carbon dioxide emissions were driven by increased use of gas as fuel at the Refinery.

The higher emissions of sulfur dioxide, carbon monoxide or other pollutants (hydrogen bromide) followed from the temporary operation of the SK-5121 emission source in abnormal conditions, which are, however, permitted and provided for in the integrated permit for the PTA Plant.
