In the present study, the effect of different kinds of impellers with different baffles or no baffle was investigated. Up-pumping pitched blade turbine (PBTU) and Rushton turbine (RT) were the two types of impellers tested. The reactor was equipped with different designs of baffles: full, half and surface baffles, or no baffles. Single (PBTU or RT) and dual (PBTU/PBTU or RT/RT) use of impellers with full (FB), half (HB), surface (SB), and no baffle (NB) combinations formed two sets of 16 experiments. The first group of experiments was close to the equilibrium line (P = 26.5 bars and T = 8.5 6 C), and the second group was deep in the equilibrium line (P = 24.5 bars and T = 2 degrees C). There was estimation of rate of hydrate formation, induction time, hydrate productivity, overall power consumption, split fraction, and separation factor. In both single and dual impellers, the results showed that RT experiments are better compared to PBTU in the rate of hydrate formation. The induction time is almost the same because we are deep in the equilibrium line while, hydrate productivity values I are higher in PBTU compared to RT experiments. As a general view, RT experiments consume more energy compared to PBTU experiments.

The Effect of Experimental Conditions on Methane (95%)-Propane (5%) Hydrate Formation Longinos, Sotirios Nik; Parlaktuna, Mahmut (MDPI AG, 2020-12-01) In the present study, the effect of different kinds of impellers with different baffles or no baffle was investigated. Up-pumping pitched blade turbine (PBTU) and Rushton turbine (RT) were the two types of impellers tested. The reactor was equipped with different designs of baffles: full, half and surface baffles or no baffles.

Kinetic studies for the production of tertiary ethers used as gasoline additives Boz, Nezahat; Doğu, Timur; Department of Chemical Engineering (2004) In the present study, the kinetics studies for etherification reactions were investigated in detail. In the first phase of present study, different acidic resin catalysts were prepared by the heat treatment of Amberlyst-15 catalysts at 220°C at different durations of time and also by the synthesis of sulfonated styrene divinylbenzene cross-linked resins at different conditions. A linear dependence of reaction rate on hydrogen ion-exchange capacity was in 2M2B+ethanol reaction. However, in the case of 2M1B+e...
Exploration of preservice teachers’ reflective judgment and argumentation skills revealed in a socioscientific issues-based inquiry laboratory course Karışan, Dilek; Yılmaz Tüzün, Özgül; Zeidler, Dana L.; Department of Elementary Education (2014) This study aimed to explore preservice teachers’ (PTs) reflective judgment skills and determine the argumentation pattern used during argumentation in socioscientific issues (SSI) based Inquiry Laboratory Course (ILC). The association between reflective judgment skills and argumentation pattern was also investigated in SSI-based ILC. The participants of the study were 20 PTs from the Department of Elementary Education at a large, research oriented public university in Turkey. Qualitative research method was...
Learner-friendly textbooks: Chemistry texts based on a constructivist view of learning Tasdelen, Ugur; KÖSEOĞLU, FİTNAT (Springer Science and Business Media LLC, 2008-04-01) In this study, the use of inquiry methods, learning cycles, a conceptual change model and analogy in creating alternative science texts was discussed. An alternative text on the topic of acids and bases was created by integrating the methods and models discussed in this paper. The alternative text and a sample of a traditional text taken from a textbook, which is still used in Turkish high schools, were given to two groups, totaling 42 pre-service teachers-the alternative text was given to an experimental g...
Analysis of Argumentation and Questioning Patterns in Argument-Based Inquiry Classrooms GÜNEL, MURAT; Kingir, Sevgi; Geban, Ömer (2012-04-01) The purpose of this study was to analyze the argument-based inquiry approach implementations with respect to questioning in the classrooms. In addition, the study aimed to explore the relationship between levels of questioning and negotiation of ideas. The study was conducted with three teachers and 146 students. The video transcripts obtained from these teachers' classrooms were analyzed through discourse analysis. The findings indicated that teachers' questioning and implementation level are two crucial f...
