Optimization of ferronickel production from Sivrihisar nickel laterite ore
Pournaderi, Saeid; Geveci, Ahmet; Topkaya, Yavuz Ali; Department of Metallurgical and Materials Engineering (2014)
In this study, pyrometallurgical treatment of limonitic laterite ore from Sivrihisar region was investigated. The run-of-mine (ROM) ore contained 1.26 wt.% Ni but was initially upgraded to 1.405 wt.% Ni by screening out the +50 mm particles. Finer than 50 mm ore was crushed to -1 mm and used in the experiments. Then, the ore was calcined at different temperatures. The optimum calcination conditions were determined as 700°C and 40 min. which resulted in 10% weight loss. At the next (prereduction) stage, the ...
Optimization of overtopping type wave energy converters on existing breakwaters
Sayar, Serim Doğaç; Özyurt Tarakcıoğlu, Gülizar; Department of Civil Engineering (2022-7)
Global electricity generation today relies heavily on fossil fuels. Therefore, the need to create innovative and reliable technologies that can consistently generate clean and renewable electricity is of great importance. Generating electricity from wave energy has great potential although, the methods used to convert wave energy has limited applications in real life. Turkey surrounded by different wave conditions is a candidate for such applications. In the literature, there are various studies in which re...
Optimization of open-tube furnace diffusion with Bbr3 liquid source for industrial p-type boron doping process
Orhan, Efe; Kökbudak, Gamze; Semiz, Emel; Es, Fırat; Turan, Raşit (Middle East Technical University; 2018-07-06)
In this study, optimization of boron emitter for n-type crystalline Si solar cells has been studied in detail. Industrial open-tube (atmospheric) furnace with BBr3 as liquid B source was utilized which is a preferred dopant for the diffusion process of n-type wafers in industry [1] [2]. During the processes, full boat (270 wafers) n-type square samples were used to investigate the uniformity from gas zone to door zone and inside the wafer. To achieve uniform boron emitters on large n-type substrates, parame...
Optimization of energy production from an underground gas storage reservoir
Sınayuç, Çağlar; Kucukeksi, MS (2000-06-01)
The aim of this study is to supply the variable gas demand from an underground gas storage reservoir during heating season by an optimal selection of production rates. Because of the interaction of many influences, parameters, and previous decisions, determination of production rates becomes so involved that the manager can no longer use intuitive judgment. The objective, therefore, is to reach an optimum decision by applying the linear programming method in problem optimization.
Optimization of CO₂ EOR and storage design under uncertainity
Bender, Serdar; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2016)
The combination of CO₂ enhanced oil recovery (EOR) and permanent CO₂ storage in mature oil reservoirs have the potential to provide a critical near-term solution for reducing greenhouse gas emissions. In the literature, although there are many studies about CO₂ storage and EOR, only a few studies have focused on maximizing both the oil recovery and the CO₂ storage. Moreover, these studies are either experimental or conducted using synthetic reservoir models. Typically, pure CO₂ has the property of mixing wi...
