Gas and dust emissions

Another environmental issue is direct and indirect greenhouse gas emissions. PKN ORLEN, by a decision of the Polish Council of Ministers (Regulation of the Council of Ministers of 1 July 2008 on the adoption of the National Plan for the Allocation of CO2 Emission Allowances in 2008–2012 under the Community Emissions Trading Scheme, Polish Journal of Laws Dz. U. no. 202, item 1248 of 14 November 2008) received CO2 emission allowances for the period 2008–2012. Those allowances will be used to calculate the actual and auditor revised emissions in the period. The Company has a permit to participate in the Community Emissions Trading Scheme for emissions from:

  • the CHP and refinery units – valid until 31 Dec 2014;
  • the petrochemical cracking unit – Olefins II – valid until 31 Dec 2017.

GHG emission is generated from processes covered by the CO2 emissions trading scheme:

  • fuel combustion in fuel combustion units (combined heat and power plant);
  • combustion in refinery unit devices, in particular furnaces, flares, stationary combustion engines;
  • refinery processes (hydrogen production, catalyst regeneration, decoking of furnace chambers (pipes).

According to the 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 PKN ORLEN is constantly balanced based on measuring circuits installed at fuel feeders. In 2008, we reported a 21% drop in fuel combustion dust emissions into the atmosphere. This is due to a lower ash content in fuel combusted in the Plant’s process boilers and furnaces compared to the year before. Meanwhile, reduced nitrogen monoxide emission (as per nitrogen dioxide) is mainly due to the modernisation of burners and maintaining oxygen regimes. A slight drop in SO2 emission is due to lower sulphur content in fuel.

Pollutant emission was constantly measured at 3 emitters at the CHP. Besides, in 2008, we performed 92 periodic checks of pollutant emission at emitters at the Production Plant in Płock, including 54 emitters subject to mandatory measuring.
