Desulphurisation plant will cut emissions

The construction of a new desulphurisation plant at a power station near Warsaw will dramatically reduce the amount of sulphur dioxide entering the atmosphere. The work will mean cleaner air for local people and help Poland to meet its environmental obligations.

The goal of the project is to build a state-of-the-art wet flue-gas desulphurisation (WFGD) plant which will deal with emissions of sulphur dioxide produced by three boilers at the Elektrociepłownia Siekierki power station. This station is the largest energy producer in the region and is run by Vattenfall Heat Poland S.A.

In addition to constructing the WFGD plant, work will be carried out to develop associated infrastructure at the power station. A channel will be created to carry un-desulphurised exhaust gas from the boilers to the new plant, and a new ventilation and heating system will be installed. A channel will also have to be built to carry the purified flue-gas to a new exhaust stack, which will also be constructed as part of the project. Existing technical systems at the power station will be modified to ensure they are compatible with the new WFGD plant.

Various machinery and equipment that can be used in the flue-gas system will be purchased as part of the project. This investment is required for various tasks including the loading and unloading of powdered limestone and for the preparation of sorbents and process water. Equipment will also be purchased to handle gypsum dehydration, sewerage purification and the removal of sludge.

Environmental dividend

The key objective is to reduce the amount of sulphur dioxide entering the atmosphere, which will help to fulfil strict environmental standards for such emissions that have been binding in Poland since January 2008. In fact, sulphur dioxide emissions from the Elektrociepłownia Siekierki station should initially be reduced by 22.7 % per year, a figure which will rise to 45.3 % once Vattenfall Heat Poland has completed its entire sulphur dioxide reduction programme.

In the end, this will result in improvements to the natural environment in and around Warsaw and the Mazowieckie province. Vattenfall Heat Poland will own the assets created through the project.

Total and EU funding

The project “Construction of a Wet Desulphurisation Plant for boilers K14, K15, K16 at ‘Elektrociepłownia Siekierki’” has a total eligible budget of EUR 89 170 445, with the EU’s European Regional Development Fund contributing EUR 5 565 604 for the 2007 to 2013 programming period.
