A high pressure thermogravimetric analyser (HPTGA) has been used to explore the effect of total pressure (100, 200 and 300 psig) on the combustion behaviour and kinetics of crude oils. In combustion with air, three different reaction regions were identified, known as low-temperature oxidation, fuel deposition and high temperature oxidation. The Coats and Redfern procedure was applied to determine the kinetic parameters of the crude oils studied.

High pressure TGA analysis of crude oils Kök, Mustafa Verşan; Price, D (1996-09-25) A high pressure thermogravimetric analyser (HPTGA) has been used to explore the effect of total pressure (100, 200 and 300 psig) on the combustion behaviour and kinetics of crude oils. In combustion with air, three different reaction regions were identified, known as low-temperature oxidation, fuel deposition and high temperature oxidation. The Coats and Redfern procedure was applied to determine the kinetic parameters of the crude oils studied.
High temperature proton exchange membrane fuel cells Ergün, Dilek; Eroğlu, İnci; Department of Chemical Engineering (2009) It is desirable to increase the operation temperature of proton exchange membrane fuel cells above 100oC due to fast electrode kinetics, high tolerance to fuel impurities and simple thermal and water management. In this study; the objective is to develop a high temperature proton exchange membrane fuel cell. Phosphoric acid doped polybenzimidazole membrane was chosen as the electrolyte material. Polybenzimidazole was synthesized with different molecular weights (18700-118500) by changing the synthesis condi...
High temperature corrosion of steels used in petroleum refinery heaters Sultan, Abdelrahman; Karakaya, İshak; Department of Metallurgical and Materials Engineering (2005) The oxidation of three different steels used in the construction of petroleum refineryheaters was investigated by using thermogravimetric analysis technique (TGA). C-5,P-11, and P-22 steel samples were tested in two different oxidizing environments; air and CO2+N2+H2O (that simulates the combustion products of natural gas) at two different temperatures; 450oC and 500oC. In air oxidation P-22 had the best oxidation resistance among the three steels at two temperatures. In CO2+N2+H2O environment,C-5 possessed...
High-speed jet flows over spillway aerators Kokpinar, MA; Göğüş, Mustafa (2002-12-01) The characteristics of high-speed air-entrained jet flow over a spillway aerator were investigated using experimental data. Three different ramp designs (as well as the case of no ramp) were tested in a channel where the bed slope was adjusted to 0, 0.17, and 0.57, respectively. The effects of aerator geometry and flow condition on the air-entrainment process within the water jet and on the pressure fluctuations in the impact region are the main focus of the investigation. An extensive data analysis was per...
Combustion characteristics of crude oil-limestone mixtures: High pressure thermogravimetric analysis and their relevance to in-situ combustion Kök, Mustafa Verşan; Price, D. (1997-12-01) High pressure thermogravimetric analysis (HPTG) was used in order to study the oxidation of crude oil in a porous medium under pressurised conditions for simulation of in-situ combustion during oil recovery. Three distinct reaction regions were observed from the HPTG curves in an oxidising environment subjected to a constant heating rate. These were low temperature oxidation, fuel deposition and high temperature oxidation. The method of Coats and Redfern was used to obtain kinetic parameters and the results...
