Surface growth is one of the major steps in the soot formation processes where most of the total mass is formed. Freshly generated soot from an ethylene diffusion flame was sampled and mixed with ethylene in a flow tube at elevated temperatures and using nitrogen as the carrier gas. The changes in the size of the soot particles after hydrocarbon addition were measured using a differential mobility analyzer. These measurements showed a significant mass increase of soot particles as a result of the hydrocarbon addition where the total number density remained the same. Soot surface growth kinetics were obtained from the changes in the size, surface area and volume distributions. The activation energy (Ea) for ethylene was obtained. Pure pyrolysis experiments for ethylene were also performed. The surface growth process yield was found to be higher than the yield of the pyrolysis process.

Modeling of underground gas storage in a depleted gas field Gumrah, F; Izgec, O; Gokcesu, U; Bağcı, Ali Suat (Informa UK Limited, 2005-07-15) It is possible to predict the behavior of fluids in permeable and porous medium under different operating conditions by using reservoir models. Since geological data and reservoir properties can be defined most accurately by reservoir models, it has been accepted as a reliable prediction tool among reservoir engineers. In this study, a gas reservoir has been modeled with IMEX Module of CMG Reservoir Simulator. Rock properties, gas composition and certain production data were entered to the model as input da...
Determination of wettability and its effect on waterflood performance in limestone medium Karabakal, U (American Chemical Society (ACS), 2004-03-01) Wettability measurement methods, the effect of wettability on fluid distribution, and fluid flow in porous media were discussed, and the influence of rock wettability on the relative permeability and recovery of oil by waterflooding were investigated. Experimental studies were conducted on a total of 23 core plugs from two different limestone formations. Synthetic brine (NaCl solution) and mineral oil, which has a viscosity ratio of similar to10, were used as the test fluids. Core samples, saturated with sy...
Characterization of tight-gas sand reservoirs from horizontal-well performance data using an inverse neural network Kulga, B.; Artun, E.; Ertekin, T. (Elsevier BV, 2018-11-01) Characterization of a tight-gas sand formation using data from horizontal wells at isolated locations is challenging due to the inherent heterogeneity and very low permeability characteristics of this class of resources. Furthermore, characterizing the uncontrollable hydraulic-fracture properties along the horizontal wellbore requires financially demanding and time-consuming operations. In this study, a reservoir characterization model for tight-gas sand reservoirs is developed and tested. The model describ...
Comparison of single particle combustion behaviours of raw and torrefied biomass with Turkish lignites Magalhaes, Duarte; Panahi, Aidin; Kazanç Özerinç, Feyza; Levendis, Yiannis A. (Elsevier BV, 2019-04-01) This study investigated the combustion behaviour of single pulverized biomass and lignite coal particles under high temperature-high heating rate conditions. Selected fuels included three important agricultural residues in Turkey (olive residue, almond shell, and hazelnut shell), and two lignite coals from the regions of Tuncbilek and Soma in Turkey. Biomass fuels were either raw or torrefied at 275 degrees C for 30 min in nitrogen. The biomass fuels were sieved to a size cut of 212-300 mu m, and the coals ...
INCIDENTAL RELEASE OF BITUMEN DURING OIL SHALE GRINDING AND IMPACTS ON OIL SHALE BENEFICIATION Altun, Naci Emre (Estonian Academy Publishers, 2009-01-01) The particle surface characteristics of oil shale and the changes in these characteristics with increasing fineness were determined. FTIR and electro-kinetic studies showed that the surfaces of oil shale particle were controlled by oxygen-rich polar groups. FTIR and XPS studies showed that with increasing fineness the polar oxides decreased and organic surface groups increased at grind sizes finer than 100 microns. Flotation was used to view the impact of the changes in surface characteristics on oil shale ...
