Impact Of A Large Medical Waste Incinerator On Air Quality, Robert Oleniacz

Robert Oleniacz

In the paper, an assessment of the compliance with air emission limit values and the impact on air quality of one of the largest medical waste incinerators in Poland, with a total capacity of about 300 kg/h (two incineration lines) is presented. The assessment took the results of continuous and periodic measurements of emissions in the plant’s installation over a period of 12 months’ operation into account. For this period, a calculation was performed for the spread of air pollutants emitted by the two operating incineration lines. According to the analysis and calculations, the analysed medical waste incineration plant does …

Suchy System Oczyszczania Spalin Ze Spalania Odpadów Niebezpiecznych – Ocena Skuteczności Usuwania Substancji Gazowych I Możliwości Spełniania Standardów Emisyjnych, Robert Oleniacz

Robert Oleniacz

The research object was a medical waste incineration plant with a flue-gas treatment system based on dry sorption agent injection to combustion gases before a high-efficiency particulate collector. A combustion system was consisted with the fluidized bed reactor (starved air gasifier) and the secondary combustion chamber. As the dry absorbent was used a mixture of high reactive hydrated lime and activated carbon. Activated carbon content in the mixture was 5-10 % by mass. The absorbent was injected in the minimal recommended amount (4-5 kg/h). Applied collector was a ceramic filter with total filtration area of 120 m2 and guaranteed outlet …

The paper presents the research results of the air pollutant emissions from the graphitising process of fine carbon products in the Acheson furnace (discharge capacity 5,5 Mg). 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 …

Ocena Funkcjonowania Instalacji Oczyszczania Gazów Odlotowych Z Procesu Grafityzacji Elektrod Węglowych W Sgl Carbon S.A. W Nowym Sączu, Marian Mazur, Robert Oleniacz, Marek Bogacki, Przemysław Szczygłowski

The paper presents a general analysis of the suitability of individual elements of the flue-gas treatment system used in SGL Carbon SA in Nowy Sacz (Poland) for the graphitization process carried out in new LWG furnaces (Castner type). The flue-gas treatment system consisted of two installations: catalytic afterburning and flue-gas desulfurization. The analysis of the suitability of various methods of flue-gas treatment was based primarily on the assessment of the effects of their application, including the reduction of concentrations of selected components in post-graphitizing gases. The work also summarizes the results of evaluation of the functioning of the whole flue-gas …

Średni Współczynnik Toksyczności Spalin Emitowanych Z Procesów Spopielania Odpadów Niebezpiecznych, Robert Oleniacz

Robert Oleniacz

The paper presents the characteristics of the Average Toxicity Factor (ATF) for combustion gases emitted from incineration of hazardous waste. Proposals for the interpretation of this factor and the possibility of its use in assessing the degree of nuisance of the process in terms of the level of air pollutant emissions were also discussed.

English title: Average toxicity factor of combustion gases emitted from hazardous waste incineration.

Bezpośrednie I Pośrednie Efekty Wprowadzenia Ciągłego Odlewania Stali W Bilansie Emisji Zanieczyszczeń Z Huty Żelaza, Marian Mazur, Marek Bogacki, Robert Oleniacz

Robert Oleniacz

This paper presents a comprehensive analysis of the impact of continuous casting technology on emissions of air pollutants from "Katowice" Steelworks in Dąbrowa Górnicza (Poland). Sources of emissions occurring in the manufacturing process and emissions levels have been identified. Implementation of continuous casting of steel has increased the efficiency of production and brought substantial ecological effects.

English title: Direct and indirect effects of introduction of continuous casting of steel in the balance sheet of pollutant emissions from "Katowice" Steelworks.

Badania Emisji Chlorowodoru I Związków Fluoru Podczas Spalania Odpadów Niebezpiecznych, Marian Mazur, Robert Oleniacz, Marek Bogacki

Robert Oleniacz

The paper presents the results of measurements of the concentration of hydrogen chloride (HCl) and fluoride compounds (as HF) in raw and purified combustion gases discharged from the incineration of selected hazardous wastes. The study included two installations operating on an industrial scale: a multiple hearth furnace and a rotary kiln incinerator equipped with a single wet flue gas cleaning systems. In the multiple hearth furnace was being incinerated sludge from coke industry. In the rotary kiln were being incinerated coal (coke) tars, contaminated cleaning rags, sawdust, used gloves, outdated pharmaceuticals and medicines, hospital waste, waste paints, varnish and lubricant, …

Emisja Zanieczyszczeń Ze Spalania Odpadów Farmaceutycznych I Poszpitalnych W Piecu Obrotowym, Robert Oleniacz, Marian Mazur, Marek Bogacki

Robert Oleniacz

The work presents the problem of management and thermal treatment of medicines and hospital wastes and investigation results of incineration of these waste in the full-scale rotary kiln with wet gas cleaning equipment (alkaline scrubber). On the basis of measurements of air pollutant concentrations in combustion gases, maximum dose of these wastes in the feed to the kiln was specified in order to ensure a relatively low stack emissions using the hypothetical high-efficiency flue-gas treatment system.
