Ocena Składu Gazów Odlotowych Z Procesów Spopielania Odpadów Niebezpiecznych Pod Kątem Trudności Oczyszczania I Toksyczności, Robert Oleniacz

Robert Oleniacz

Tightening of the European Union law in the field of the air emission limit values from waste incineration causes necessity for existing and new incineration plants to conform to the standards. It will often involve modernization of the flue gas cleaning system. Proposed in the paper the methodology of evaluation of the combustion gases composition in point of view cleaning difficulty should be useful to this end. Average toxicity factors for hazardous waste incineration flue gases were defined as well. Among other things they can be used in comparative analysis of the air pollutant concentration in the raw gas (before …

Czynniki Wpływające Na Skład Spalin I Wielkość Emisji Zanieczyszczeń Z Procesów Termicznego Przekształcania Odpadów Niebezpiecznych, Robert Oleniacz

Robert Oleniacz

The work summarizes factors influencing on air emissions from various full-scale hazardous waste incinerators (rotary kiln, multiple hearth furnace, starved-air incinerator, fluidized bed incinerator, liquid injection incinerator). Air pollutant emissions from hazardous waste incineration can be minimized not only by flue-gas cleaning. There are many factors that influence on flue-gas composition and the quantity of air pollutants formed during incineration: the type, the composition and the quantity of waste, the way of waste introducing to the incinerator, excess air ratio, combustion temperature, retention time of exhaust gases etc. Special attention was paid to the loading of waste and incineration conditions …

Ocena Udziału Huty Katowice W Poziomie Opadu Pyłu, Ołowiu I Kadmu Na Powierzchnię Terenu Wokół Zakładu, Marian Mazur, Robert Oleniacz, Marek Bogacki

Robert Oleniacz

The paper presents the results of modeling of deposition on the land surface of dust, lead and cadmium emitted from the "Katowice" Steelworks. The calculations were carried out in the vicinity of the location of the dust deposition measuring points existing around the plant. Computational data were compared with the results obtained from direct measurements for the same calendar year. The responsibility of this plant in shaping the level of dust and heavy metal deposition in the region of the protective zone was determined.

Prognoza Wpływu Na Stan Zanieczyszczenia Powietrza Procesu Unieszkodliwiania Odpadów Pestycydowych W Piecu Cementowym, Marian Mazur, Robert Oleniacz, Marek Bogacki

Robert Oleniacz

The paper presents the general conditions associated with running of pesticide waste co-incineration in rotary kilns for cement clinker burning, and describes the behavior of toxic substances entering to this process with waste materials or forming as the result of thermal decomposition. Additional air emissions and their impact on air quality were also assessed.

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.

Dobór Systemu Oczyszczania Gazów Odlotowych Ze Spalania Odpadów Niebezpiecznych, Robert Oleniacz

Robert Oleniacz

The flue gas cleaning system is usually one of the most costly elements of the installation to the incineration of hazardous waste. Adapting the system to the actual needs could therefore bring obvious economic benefits.

The paper presents the method of the preselection of the configuration of the cleaning system based on knowledge of the level of concentration of selected components of the raw exhaust gas (sulfur dioxide, hydrogen chloride, hydrogen fluoride, total dust, mercury, cadmium and thallium, and other heavy metals). Twelve examples of flue-gas cleaning systems were proposed and extreme concentration values of the substances in the raw …

Niezorganizowana Emisja Zanieczyszczeń Powietrza Z Hal Ciągłego Odlewania Stali, Marian Mazur, Marek Bogacki, Robert Oleniacz, Agnieszka Łopata

Air pollutant emissions occurring in an uncontrolled way do not be subject to the regular verification just like it takes place in case of the controlled sources, for which the routine measurements are carried out. In the paper a methodology and the results of some research were presented. The research consisted in determination the quantity of dust and gaseous pollutants emitted from the halls in which technological processes connected with the steel continuous casting were being run. Stocktaking of all the uncontrolled emission sources were carried out and the technological operations predominating in the level of the particle matter and …

Lead Isotope Tracking Of Atmospheric Response To Post- Industrial Conditions In Yerevan, Armenia, Charles Dunlap, Robert Kurkjian

Charles Dunlap

Temporal gradients in environmental lead concentrations and isotopic compositions trace the rapidly shifting transition from high to low industrial emissions in Yerevan, Armenia following the dissolution of the Soviet Union in the early 1990s. Shortly after the breakup, in 1995 and 1996, atmospheric lead concentrations averaged ~0.4 µg/m3 and the combustion of leaded gasoline was the primary source of industrial lead emissions in Yerevan. But by 1998, unleaded gasoline was predominant and atmospheric lead concentrations had decreased by two orders of magnitude to ≤ 0.003 µg/m3 because industrial lead emissions from stationary sources had also been radically curtailed. The increased …

An Investigation Of Environmental Racism Claims: Testing Environmental Management Approaches With A Geographic Information System, Gregg P. Macey

Gregg P. Macey

The purpose of this research was to explore the concept of an environmental racism claim through the use of several environmental management tools. The EPA's Toxics Release Inventory, Cumulative Exposure Project, and the Los Angeles County Department of Health Services' Hot Zone Census Tract Assessment were combined with racial and socioeconomic data to test claims that minorities in South Central Los Angeles are disproportionately exposed to environmental lead. Multivariate analysis indicated that race is strongly associated with the number of cases of elevated lead levels in South Central, irrespective of poverty status. Proximity to point sources, a common focal point …
