The desulphurisation process involves the injection of a limestone slurry, which removes up to 95 per cent of the sulphur dioxide which is one of the main causes of acid rain.
The contract execution (in the formula "turnkey") a complete, modern flue gas desulphurisation plant for two steam boilers OP-230 K-7 and K-8 in the CHP Bialystok in order to reduce SOx emissions to = 130 mg / Nm3 (understood as total SO2 + SO3) in dry flue gas at O2 = 6%, and reduce dust emissions to = 10 mg / Nm3 in the dry flue gas at O2 = 6% during fuel combustion of coal.
This would involve the modernisation or replacement of dusters on boilers, the construction of a desulphurisation unit, installation of low NOx burners and the conversion of combustion for lower sulphur content fuel.
This Agreement, both in terms of the installation of a new CCGT and the development of new technologies, is a clear indication of ENDESA's commitment to clean fuel, including not only the use of natural gas, desulphurisation, denitrification and reduction of new contaminants but also the capture and storage of CO2 which could help the use of coal as a fuel in the future.

The installation of the new desulphurisation system in the two oldest groups at this power station (G1 and G2 from 1981 and 1982 respectively), with a total capacity of 250MW (the station also has two other groups of 130MW each which already have this system installed), will allow annual reductions in emissions of sulphur dioxide (SO2) of nearly 75% and an 80% reduction of particles.
