REACTIVITY OF MARBLE WASTES FOR POTENTIAL UTILIZATION IN WET FLUE GAS DESULPHURIZATION Altun, Naci Emre (2016-01-01) Wastes of most marble types are distinguished with their superior CaCO3 content and potential to utilize them as an alternative to limestone. Control of SO2 using marble wastes in wet flue gas desulphurization (WFGD) units of coal fired thermal power plants is an important opportunity. In this study, nine types of marble wastes were evaluated in terms of their ability to dissolution (reactivity) in an acidic environment. The reactivity was expressed as fractional conversion with time with respect to the che...
Reactivity of limestones of different sources for flue gas desulfurization application Gülsün, Mehtap; Hoşten, Çetin; Department of Mining Engineering (2003) In today's world where millions of tons of pollutants are discharged into the atmosphere, continually increasing population and industrialization lead to ever increasing demand for energy which, in turn, leads to a continual increase in the amount of pollutants released into the atmosphere. Sulphur dioxide generated as a result of burning coal is one of the most significant pollutants in the atmosphere and has negative effects on both living beings and non-living things. There are wet and dry processes whic...
Reactivity of CO2 during thermal cracking of heavy paraffins under supercritical conditions Karakaş, Gürkan; Doğu, Timur (1997-11-01) Thermal cracking of n-hexadecane was investigated in a temperature range of 450-600 degrees C in the presence of CO2. Effects of pressure and temperature on product distribution were experimentally determined under both subcritical and supercritical conditions. At 1.2 MPa and with a CO2 to n-C-16 mole ratio of 25, C-6-C-14 olefins, C-10-C-17 paraffins, and C-5-C-10 fatty acids were identified in the liquid product. Experiments conducted at 4.5 MPa (supercritical) yielded higher selectivities for fatty acids...
Reactivity of limestones from different sources in Turkey Hoşten, Çetin; Gulsun, M (Elsevier BV, 2004-01-01) This paper presents a study on the reactivity of natural limestones from five deposits in Turkey. The conversion rates of carbonates in size fractions of the samples were measured in a stirred suspension of 2.5 1 at 20 degreesC and a constant-pH value of 5 obtained with the addition of HCl solutions by a pH control pump. Particle size and the dolomite content of the limestones were found to be the most influential parameters in the reactivity measurements.
Reactivation potential of indicator bacteria in anerobically digested sludges after dewatering processes Erkan, Müge; Sanin, Faika Dilek; Özdağ, Hilal; Department of Biotechnology (2011) Anaerobic digestion process which has long been known to successfully reduce the organic content of sludge is one of the most common alternatives to meet pathogen reduction requirements for particular classes of biosolids. However, it has recently been reported that, significantly higher densities of indicator bacteria have been measured in dewatered cake samples compared to samples collected right after anaerobic digestion. In addition, this increase in bacterial population has been commonly observed after...
