The Effect Of Carbonate Rock Wettability On The Performance Of Low Salinity Water Flooding: An Experimental Approach, Hildah Nantongo
The Effect Of Carbonate Rock Wettability On The Performance Of Low Salinity Water Flooding: An Experimental Approach, Hildah Nantongo
Chemical and Petroleum Engineering Theses
The performance of low salinity waterflooding (LSWF) in different wettability environment is still unclear for the oil industry. The concessions among researchers are that low salinity does not work in water-wet carbonate oil reservoirs. In this project carbonate core flooding experiments on cores with different wettability’s conditions, including water-wet, oil-wet, and intermediate wettability were performed at reservoir conditions of pressure and temperature. Seawater was selected as a base water and its concentration & composition were modified through dilution and/or spiking with sulfate. The base water was diluted with water 10 and 50 times and spiked with sulfate to 2 and …
Calcium Phosphate/Ionic Liquid Ptfe Composite Membrane For Proton Exchange Membrane Fuel Cell Applications, Ahmad Ibrahim Hasan Ka’Ki
Calcium Phosphate/Ionic Liquid Ptfe Composite Membrane For Proton Exchange Membrane Fuel Cell Applications, Ahmad Ibrahim Hasan Ka’Ki
Theses
The dependence on fossil fuels can be possibly reduced by the utilization of renewable energy sources. Fuel cells offer a promising alternative for renewable power generation. Among the various types of fuel cells, Proton Exchange Membrane Fuel Cell (PEMFC) is recently attracting attention due to its several advantages of high-power density, all solid structure, and silent operation. The diverse types of materials used in this type of fuel cell raised drawbacks related to fuel cell cost and durability. By far, Nafion of DuPont is still the current state-of-the-art membrane for PEMFCs. It is known for its high ionic conductivity and …
Growth Of Microalgae For Simultaneous Treatment Of Industrial Wastewater And Biodiesel Production, Mohammed Ahmad Abujayya
Growth Of Microalgae For Simultaneous Treatment Of Industrial Wastewater And Biodiesel Production, Mohammed Ahmad Abujayya
Chemical and Petroleum Engineering Theses
The treatment of industrial wastewater contaminated with phenols is among the main challenges in the chemical, and particularly the petrochemical industry. Phenols, which present in considerable amounts in industrial wastewater, are toxic even at low concentrations. Therefore, it is essential to reduce their concentrations in water to harmless levels before being discharged. On the other hand, the dependence on the conventional fossil sources of energy, which is non-renewable, is not sustainable and can cause harmful environmental impacts. Therefore, in this work, the dual utilization of microalgae as a cheap and efficient means to remove phenolic compounds commonly found in refinery …
Developing A New Formula For Predicting Oil Recovery Factor In Water Flooded-Heterogeneous Reservoirs, Mohamed Khaled Aljifri
Developing A New Formula For Predicting Oil Recovery Factor In Water Flooded-Heterogeneous Reservoirs, Mohamed Khaled Aljifri
Theses
In this work, two sets of empirical correlations were developed for predicting the recovery factor (RF) in water-flooded layered oil reservoirs. The first set of these correlations encompasses four key parameters believed to have a significant impact on waterflooding performance, namely, reservoir heterogeneity (permeability variation coefficient), injected water viscosity, permeability anisotropy (ratio of vertical permeability to horizontal permeability), and water injection rate. This first set consists of two expanded forms, one for predicting the RF at water breakthrough time (BT) and the other for predicting the RF at the end of the project (EOP). Out of the aforementioned four key …
Designing Metal-Organic Frameworks For Natural Gas Storage And Delivery, Labeeb Ali
Designing Metal-Organic Frameworks For Natural Gas Storage And Delivery, Labeeb Ali
Chemical and Petroleum Engineering Theses
Natural gas is major resource in UAE, constitute about 90% methane and as compared to other fossil fuels, it is more environmentally friendly. Energy demand from natural gas can be projected to exceed two hundred exajoules per year in 2040. In the UAE, many natural gas filling stations are already built for utilizing natural gas as a vehicle transportation fuel where these materials have potential applications to store and deliver this fuel. This research aims to study various kinds of Metal-Organic Frameworks, and to investigate adsorption properties for the storage of natural gas and its delivery. MOFs possess porous material …

Poly (Lactic Acid)/Nanoclay Nanocomposites For Packaging Applications, Maissa Akram Adi
Theses
With increasing stringent environmental regulations and attempts to reduce dependence on fossil fuels for polymer production, bio-based polymers are receiving appreciable global attention. In this context, bio-based poly (lactic acid) (PLA) is one of the most frequently used polymers in packaging applications. However, despite of its high versatility, this polymer is limited in packaging applications due to its low mechanical properties. The two-dimensional nanofillers such as nanoclay and graphene are well known for improving the thermo-mechanical properties of polymers at low concentrations. However, increasing higher filler concentration to improve barrier properties of polymers reduces their mechanical properties which is a …
