ORLEN ORLEN Group 2017
Integrated Report

Emissions and Ambient Concentrations



Air emissions of pollutants are monitored through periodic or continuous measurements, so that actual emissions can be compared against emission limits defined in the relevant integrated (IPPC) permits on an ongoing basis.

Substances accounting for the largest percentage of total air emissions from the ORLEN Group’s installations include: sulfur dioxide, nitrogen oxides, carbon monoxide and dioxide, as well as particulate matter, including PM 2,5 and PM 10. They are generated mainly from the combustion of fuels to produce electricity and heat, as well as in the refining and chemical processes. There are also volatile organic emissions and process-specific emissions.

Total ORLEN Group’s air emissions, including of carbon dioxide, reached 15,226,911 Mg in 2017.

In 2017, periodic measurements of air emissions from the petrochemical, refining and CHP units in Płock and the PTA plant in Włocławek revealed no exceedance of the permitted emission levels from the integrated permits. Similarly, data from the continuous monitoring system installed at the emission sources of the on-site CHP plant were in line with the Minister of Environment’s Regulation on Emission Standards for Installations.

At the ORLEN Group companies, total air emissions in 2017 largely remained at the 2016 level.

Air emissions from all ORLEN Group companies, by type of substance [Mg]

Substance Emissions [Mg]
  2017 2016 change [%]
Sulfur dioxide 20,462 21,688 (5.65)
NOx 10,516 9,680 8.64
Carbon monoxide 4,794 3,508 36.67
Particulate matter 1,665 1,520 9.54
Other substances 13,329 14,184 (6.03)
Total 50,766 50,579 0.37

Nearly 90% (11,945 Mg) pf ‘other substances’ are emissions of volatile organic compounds.

Ambient concentrations

In 2017, air quality monitoring in the vicinity of the Płock production plant covered the same substances as in the previous year: O3, CO, SO2, NO2 and BTX, and was carried out from an automatic monitoring station located outside the plant’s premises − at Junior High School No. 5. The station has been included in the State Environmental Monitoring programme, and atmospheric measurements are automatically sent to the Inspector of Environmental Protection for the Warsaw Province in Warsaw.

Analysis of the 2017 measurement readings indicates that the Company complied with the environmental standards for all measured pollutants, as laid down in the Minister of Environment's Regulation of August 24th 2012. There were no instances of the maximum annual average concentrations being exceeded for any substance.

Besides PKN ORLEN, ambient air quality monitoring is carried out by three companies: ANWIL, ORLEN Lietuva and Unipetrol.

At ANWIL, off-site periodic measurements are taken at two locations to measure the concentrations of vinyl chloride (C2H3Cl) and 1,2-dichloroethane (C2H4Cl2), while on-site measurements additionally cover ammonia (NH3) and nitrogen dioxide (NO2).

ORLEN Lietuva monitors ambient concentrations at four off-site locations, within the so-called sanitary zones. Measurements are taken once a day to monitor the levels of VOCs, benzene (C6H6), toluene (C7H8), ethylbenzene (C8H10), carbon monoxide (CO), hydrogen sulfide (H2S) and nitrogen dioxide (NO2).

Monitoring at Unipetrol covers ambient concentrations of sulfur dioxide (SO2), nitrogen oxides (NO2) and benzene (C6H6). Ambient concentrations are monitored on a continuous basis from an automatic station.

A comparison of monitoring data against permissible levels has shown compliance with applicable legal requirements.

Management of greenhouse gas emissions

Direct greenhouse gas (GHG) emissions at the ORLEN Group include emissions reported under the EU Emissions Trading Scheme (EU ETS). There are no biogenic CO2 emissions. There are also CO2 emissions not covered by the EU ETS, which totalled 798,442 Mg in 2017.
In 2017, greenhouse gas emissions were balanced monthly for the Group’s units which participate in the Emissions Trading Scheme (ETS). The extent to which the allocated CO2 emission allowances were utilised was monitored on an ongoing basis for each unit.

The largest increase in CO2 emissions was reported for PKN ORLEN, after the CCGT unit in Włocławek was brought on stream, and for Unipetrol RPA, after its steam cracker was restored to normal operation.
The results of independent carbon emissions verification were positive for all units of the ORLEN Group.

The ORLEN Group monitors emissions against its allowances on an ongoing basis, seeking to ensure that it has the required allowance amounts.
