The aim of this study was to investigate the effect of feed time of the oil phase on the average droplet size of Pickering emulsions produced in stirred tanks. Three types of impellers were tested: RT, up-pumping PBT (PBTU), and down-pumping PBT (PBTD). All the impellers were tested at two sizes, T/3 and T/2. All configurations were compared at constant tip speed, power per mass, and impeller Reynolds number. The droplet diameters were measured in Mastersizer (R) 3,000 (Malvern). The results showed that an increase in feed time causes a reduction in the average droplet size. At lower impeller speeds and higher feed times, the effect is more pronounced. It was found that some other geometric parameters also have an impact on the average droplet size.

Effect of operational parameters on anaerobic co-digestion of dairy cattle manure and agricultural residues: A case study for the Kahramanmaras region in Turkey Alkaya, Emrah; Bayramoğlu, Tuba Hande; DEMİRER, GÖKSEL NİYAZİ (Wiley, 2010-12-01) The aim of this study was to investigate the effect of temperature and hydraulic retention time (HRT) on anaerobic co-digestion/biomethanation of cattle manure and agricultural residues (clover, grass and wheat straw). For this purpose, 12 semi-continuous reactors, fed with/without agricultural residues, were operated under varied temperature (10 +/-, 20 +/- and 35 +/- 1 degrees C) and HRT (20 and 30 days) conditions. During the experimental study, all reactors were fed once on a daily basis and operated wi...
Effect of pressure on combustion kinetics of heavy oils Bağcı, Ali Suat (Informa UK Limited, 2005-07-01) In this study, 16 experiments were conducted to study the effects of pressure on crude oil oxidation in limestone medium. Karakus (29 degrees API), Beykan (32 degrees API), Bati Raman (12 degrees API), Camurlu ( 12 degrees API), Adiyaman (26 degrees API), Garzan (28 degrees API) and Raman (18 degrees API) crude oil from Turkish oil fields were used. The mixture of limestone and the crude oil was subjected to a controlled heating schedule under a constant flow rate of air. The produced gas was analyzed for i...
Effect of welding parameters on the susceptibility to hydrogen cracking in line pipe steels in sour environments Yavaş, Özgür; Doruk, Mustafa; Department of Metallurgical and Materials Engineering (2006) In this study, hydrogen induced cracking (HIC) behavior of welded steels used in petroleum lines under sour petroleum environments was investigated. The testing environment in NACE TM0284-2003 standard was used in order to simulate sour petroleum environment. In order to investigate behavior of welding parameters, used in pipe production, on HIC, welds were done with different line energies. Two different API X-65 steels were used in welding operations. The specimens taken from welded zones were tested in t...
Effect of crude oil type and heating rate on combustion of crude oil-lignite mixtures Kök, Mustafa Verşan (Elsevier BV, 1992-01-01) Research was conducted to investigate the possibility of upgrading low-quality lignites by mixing them with heavy crude oils. Three crude oil samples with API gravities of 12.9, 18.7 and 26.7 were mixed with lignite to form mixtures of 10 and 20% oil content. Thermal analysis experiments were conducted at non-isothermal heating conditions at heating rates of 5-100 K min-1. Differential thermogravimetric data were analysed using an Arrhenius-type reaction model assuming a first-order reaction. The results in...
Effect of heating rate on thermal properties and kinetics of raw and cleaned coal samples Özbas, Kazim Esber; Hicyilmaz, Cahit; Kök, Mustafa Verşan (Informa UK Limited, 2003-01-01) In this article, thermogravimetry (TG/DTG) was used to determine the effect of heating rate on the thermal properties and kinetics of raw and cleaned coal samples from Soma, Tuncbilek, and Afsin Elbistan regions. TG/DTG experiments were carried out at 4 different heating rates (5, 10, 15, and 20degreesC/min). Generally, for all of the samples higher peak and burnout temperatures were measured with an increasing heating rate. Kinetic parameters of the samples were determined using an Arrhenius-type kinetic m...
