Opis:: Results of ChemCad©6.0 simulation have been presented on usability of natural soda ash production process waste in order to remove SO₂ from flue gas. Properties and concentrations of the solutions used in this study belong to the waste stream of Eti Soda Inc., and the flue gas compositions were acquired from an existing thermal power plant. SO₂ and H₂O feed rates and flue gas entrance temperature to the absorption tower were optimized through the response surface methodology (RSM) in order to attain highest SO₂ removal yields. It has been found that SO₂ removal remained at 33.83% when the waste composition was lower than 2 wt. % while 100% SO₂ removal was reached as the waste composition was increased to 8 wt. %. This result clearly demonstrates that treatment of natural soda ash production process waste can be done safely and economically while serving as an SO₂ removal agent at the same time.

Opis:: The results of pilot plant investigations of simultaneous removal of NOx, SO2 and Hg from flue gas with ozone as the oxidizing agent and the spray tower absorber with NaOH solution as the absorbent have been presented. Flue gas was delivered into the pilot plant at the flow rate of 200 m3/h from the coal fired OP-430 boiler. The effectiveness of NOx removal was over 95% when the molar ratio O3/NO reached 2.0. Sulfur dioxide was practically completely washed out from flue gas in the absorber at the liquid-to-gas ratio 7.5 dm3/m3. The effectiveness of Hg removal in the studied system was approximately 80%. It was pointed out that CO concentration in flue gas could considerably increase the ozone consumption. The effect of carbon dioxide in flue gas on the chemistry of absorption due to hydroxides conversion into carbonates and bicarbonates was noticed.

Opis:: Exhaust gases with high SO2 concentrations are emitted from combustion of high sulphur fossil fuels and from different industrial processes (e.g. copper smelter and sintering plants). The application of the electron beam process for SO2 and NOx removal from such flue gases was investigated. A parametric study was carried out to determine the SO2 and NOx removal efficiency as a function of temperature and humidity of irradiated gases, absorbed dose and ammonia stoichiometry. The efficiency 90–95% of SO2 removal was obtained in the optimal treatment conditions with an inlet SO2 concentration of up to 15% vol. The synergistic effect of high SO2 content on NOx removal was indicated. The collected by-product was a mixture of ammonium sulphate and nitrate. The content of heavy metals in the by- -products was many times lower than the values accepted for commercial fertilizers.

Opis:: This paper reports studies on the influence of vanadium concentration on the catalytic activity of DESONOX catalysts (in DESOX reaction) based on modified montmorillonite from Jelsovy Potok. The investigation of the influence on the physicochemical properties of the catalysts on their behaviour has also been studied.
