The paper presented methods of reducing emissions of sulfur oxides, nitrogen and greenhouse gases. Flue gas desulphurization takes place as a result of wet, dry and semidry. Waste gas denitrification is carried out through the application process by the catalytic reduction of dry and wet by oxidation. While the separation of CO2 from flue gases is done by: absorption, adsorption, membrane separation and cryogenic fractionation. An example is here Bełchatów Power Plant, which seeks to make full use of these methods, using newer technologies, so as to maintain the standards imissions.

(Data obrony: 2017-09-27) Szczęchal, Magdalena
Wydział Geologii, Geofizyki i Ochrony Środowiska
W pracy zostały opisane istniejące metody odazotowania spalin w energetyce zawodowej w Polsce. w części wprowadzającej zostały scharakteryzowane tlenki azotu oraz opisano ich powstawanie. Przedstawiono obowiązujące normy dotyczące emisji tlenków azotu z podziałem na nominalną moc cieplną źródła. Opisano związki azotowe występujące w paliwach oraz prześledzono redukcję tlenków azotu w procesach spalania. Praca przestawia stosowane metody odazotowania spalin z podziałem na wtórne i pierwotne oraz prezentuje jakie metody są stosowane w danych elektrowniach w Polsce, wraz z przedstawieniem wad i zalet danych rozwiązań.

This diploma thesis presents technologies used to reduce sulfur oxides and nitrogen oxides emissions. The basic legal acts establishing the limits of compounds emission were discussed. The processes of formation the sulfur and nitrogen oxides from fuel combustion in power boilers were presented. The methods of reducing the emission of these pollutants were described. The installations of flue – gas cleaning in plants producing electricity and heat, existing in Poland, were described. The efficacy of the methods of the flue – gas desulfurization and denitrification was defined.

Wykorzystanie metody chromatografii gazowej do oceny procesu denitryfikacji w wodach triasowego zbiornika wód podziemnych rejonu Opola

The studied aquifer - Major Groundwater Basin (MGWB) 333 is located near Opole in Muschelkalk carbonate rocks. The hydrological conditions of the investigated area are determined by monoclinal structure of the geological formations. On the outcrop of the Muschelkalk formation, the aquifer is unconfined and the recharge rate and conductivity are relatively high. In the northern part of the aquifer, which is covered with a confining unit of the Keuper formation, the average hydraulic conductivity and the flow velocity decrease. Nitrates have been the main indicator of groundwater contamination. The high NO3 concentrations which are observed in the outcrop area decrease significantly in the zone near the border of the Kauper extent. There are two main reasons of the nitrate concentration decline: denitrification process and groundwater age. Denitrification was identified using data on dissolved gas concentrations which were detected and quantified by gas chromatographic method. The expected denitrification effects have been observed in the samples from transitional zone of the Triassic aquifer.
