Item type:Article, Access status: Open Access , Emisja zanieczyszczeń z procesu grafityzacji elektrod węglowych w piecach LWG (Castnera). Część 1. Wybrane substancje gazowe(Wydawnictwa AGH, 2005) Mazur, Marian ; Oleniacz, Robert ; Bogacki, Marek ; Szczygłowski, PrzemysławIn the paper the results of measurements of quantity pollutants originated and emitted to air from resistor stoves of type LWG (Castner) were introduced. The investigation was carried out during graphite process of coal electrodes, until moment of end of ventilation the stove across applied installations of cleaning of cool gases (catalytic burning and the wet desulphurization). The measurement results of $CO$, $CO_{2}$, $HC+H_{2}$, $SO_{2}$, $H_{2}S$, $CS_{2}$, $NO$, $NO_{2}$, $NH_{3}$ as well as chosen hydrocarbons $(C_{1}-C_{6})$ and aromatic hydrocarbons (BTX) were presented. In result of conducted investigations was qualified courses of changeability of concentrations in gases these substances before and for the cleaning system. The effectiveness of the substance removing from exhaust gases was estimated as well as range of occurrence of their maximum release. The additional investigations of catalytic burning showed, that this process causes the formation of the additional quantities of benzene.Item type:Article, Access status: Open Access , Emisja zanieczyszczeń z pieca Achesona do grafityzacji wyrobów drobnych(Wydawnictwa AGH, 2006) Mazur, Marian ; Oleniacz, Robert ; Bogacki, Marek ; Szczygłowski, PrzemysławIn the paper research results of the air pollutant emissions from the graphitising process of fine products in the electric resistance Acheson furnace (discharge capacity 5,5 Mg) were presented. Research was performed for two kinds of raw material inputs (based on petroleum coke and pitch coke). Approximately 40-hours measurement series were carried out for each material including mainly such substances like carbon monoxide, hydrocarbons, nitrogen oxides, sulphur dioxide, hydrogen sulphide, carbon disulphide, ammonia, benzene, toluene, xylenes, total dust, tar substances and polycyclic aromatic hydrocarbons. Both average and maximum concentrations and mass streams in the flue gases and average emission factors were presented for the substances.Item type:Article, Access status: Open Access , Emisja zanieczyszczeń ze spalania odpadów podestylacyjnych z produkcji witaminy C w piecu fluidalnym(Wydawnictwa AGH, 2005) Oleniacz, RobertIn the paper some results of continuous or periodical measurements of selected air pollutant concentrations and mass streams in the flue gases from liquid waste incineration in a fluidized bed incinerator were presented. During the researches distillation tails from vitamin C production, that is waste traces from regeneration such solvents as for example ethylene chloride, chloroform or trichloroethylene were incinerated. As a result of the researches there was determined optimal temperature of the fluidized bad in which the waste incineration should be carried out to minimization of CO and $NO_{x}$ formation. Required effectiveness of HCl removal from combustion gases to comply with the emission limit values was presented as well. Applied in the installation alkaline fluidized absorbers working on the parallel arrangement were not sufficient to achieve it.Item type:Article, Access status: Open Access , Emisja zanieczyszczeń z procesu grafityzacji elektrod węglowych w piecach LWG (Castnera). Część 2. Wybrane substancje pyłowe(Wydawnictwa AGH, 2006) Mazur, Marian ; Oleniacz, Robert ; Bogacki, Marek ; Szczygłowski, PrzemysławIn the paper the measurement results of quantity of dust pollutants originated and emitted to air from resistor stoves of type LWG (Castner) during graphite process of coal electrodes were introduced. The investigation was carried out for total dust, total tar substances and polycyclic aromatic hydrocarbons (PAHs). The measurements were performed both before and after the flue gas control system (catalytic burning and wet cleaning). Thus changes of the substance concentrations in the gases for the cleaning system were estimated. As a result of the investigation was conclusion that the graphite process of coal electrodes in LWG stoves is not a significant source of dust emissions. Although there is occurred increasing of total tar substances and PAHs concentrations in the gases and changing of PAHs profile within the catalytic reactors using for the flue gas burning.
