The first intention of this research is to identify specific CO2-philic solids from two candidates, namely sugar acetates and tert-butylated aromatics, which can be used to separate high pressure CO2 from H2. In this work, many of these solids were found to melt in the presence of high pressure CO2 (600 ¨C 1000 psi) and absorb large amounts of CO2. It was hoped that upon exposure to a 1:1 CO2/H2 high pressure gas mixture that was selected to be representative of a shifted gasifier effluent strea...

SummaryThe displacement of oil from reservoir rock pore spaces is a function of many interacting variables, amongst which the reservoir wetting state has been shown to be one of the important affected by the rock lithology, oil chemistry and brine salinity. A finding from previous research says that the injection brine into oil saturated core plug increased oil recovery. Based on this the objective of this master thesis is to investigate the effect of brine concentration on flow properties in tw...

Knowledge regarding carbon dioxide (CO2)-brine interfacial tension (IFT) is important for petroleum industry and Carbon Capture and Storage (CCS) strategies. In petroleum industry, CO2-brine IFT is especially importance for CO2 – based enhanced oil recovery strategy as it affects phase behavior and fluid transport in porous media. CCS which involves storing CO2 in geological storage sites also requires understanding regarding CO2-brine IFT as this parameter affects CO2 quantity that could be se...

Brine and disordered interfacial layers (DILs) on ice are known to significantly alter the interaction between trace gases and ice surfaces. In order to better predict the impact of a warming climate on atmospheric composition, a quantitative physical understanding of the interaction between ice surfaces and key atmospheric trace gases is essential. In the series of complementary studies presented in this dissertation, theoretical and experimental techniques were employed to gain insight into th...

The mixture of hydrochloric acid and magnesium chloride is a good lixiviant for the processing of sulfide minerals, concentrates and matte samples. The proton activity in this mixture deviates positively from ideal activity. This enhances the leaching power to break sulfide lattices down and to dissolve metals into solution. Magnesium (chloride) was chosen because it is one of a few reusable salts among alkali and alkali earth metal chlorides. The thermodynamic properties of this mixture are bes...

The mining industry is a water usage intensive industry that generates large volumes of wastewater. This wastewater is technically difficult to treat when it is very saline. Large quantities of reagents are needed for chemical treatment, which is very expensive.

<p>The primary aim of these coal fired industries for co-disposing fly ash and brine was to use the fly ash as a sustainable salt sink. It is therefore important to study the interaction chemistry of the fly ash-brine systems to fully understand the leaching and mobility of the contaminant species, and to determine the possibility of capturing the salts from the brine solution when fly ash and brine are co-disposed. In order to achieve the aims and objectives of this study, several leaching proc...

Delineating the extent of brine contamination in shallow groundwater systems using piezometers is costly and does not provide adequate data resolution. Direct-push (D-P) electrical conductivity (EC) profiling enables rapid in situ measurements of bulk soil EC (ECa) at the cm scale.

The effect of brine ionic composition on oil recovery was studied for a limestone reservoir rock at a high temperature. Contact angle, imbibition, core flood and ion analysis were used to find the brines that improve oil recovery and the associated mechanisms. Contact angle experiments showed that modified seawater containing Mg[superscript 2+] and SO4[superscript 2-] and diluted seawater change aged oil-wet calcite plates to more water-wet conditions. Seawater with Ca[superscript 2+], but witho...

A limited number of laboratory studies and pilot programs have been reported in chemical Enhanced Oil Recovery (EOR) flooding of carbonate reservoirs (Adams & Schievelbein, 1987). Fewer still have involved surfactants in limestone reservoirs. No surfactant/polymer flood on a field wide basis of a carbonate reservoir has ever been documented in the literature (Manrique, Muci, & Gurfinkel, 2010). This void represents a colossal opportunity given that nearly a third of the 32 billion barrels of oil...

Terahertz line-images of surfactant-stabilized dodecane(C 12 H 26 )-brine emulsions are obtained by translating the emulsified region through the focus of a terahertz time-domain spectrometer, capturing a time-domain waveform at each vertical position. From these images, relative dodecane content, emulsion size, and stability can be extracted to evaluate the efficacy of the surfactant in solvating the dodecane. In addition, the images provide insight into the dynamics of concentrated emulsions a...

The system under investigation is the crude oil/brine/mineral (COBR) system. Deposition of polar asphaltenes from oil causes mineral wetting to alter from strongly water-wet to less water-wet. The degree of alteration depends on the hydrophobicity of asphaltene and the amount of deposition, which depends on many factors such as asphaltene content and solvency of the oil, acid and base content of the oil, brine pH and salinity, aging condition, and mineral type. Bulk and interfacial physico-chemi...

The potash industry in Saskatchewan produces potash tailings as a waste material. These tailings are transported in a brine slurry to the tailings facility where they are spigotted onto the tailings pile. The current maximum height of the potash tailings piles in Saskatchewan ranges from 50 to 60 meters, in which only the bottom 3 to 5 meters of tailings is saturated. In the management of these waste piles, concerns regarding the environmental impact of the tailings pile on the existing groundwa...

Potash plants handle very corrosive raw materials and several corrosive intermediates and by-products. Several corrosion problems are encountered during potash production due to the prevalent conditions of high pressures and temperatures, high fluid velocities, abrasion, erosion, and the presence of very corrosive chemicals and by-products. The corrosion wear of materials results in severe corrosion damage and other forms of degradation. Corrosion wear is defined as the degradation of materials ...

In recent years, numerous studies have been done on the alteration of the permeability of clayey soils as a result of exposure to concentrated organic or inorganic permeants. These permeability changes have been attributed to either changes in the microfabric or the macrofabric of the clays as a result of physico-chemical interactions between the clay particles and pore fluid chemistry. However at the present there still remains no theoretical framework for interpreting the mechanism for changin...

Brine shrimp (genus Artemia) are small (8 to 12 mm long) cosmopolitan crustaceans (Anostraca) found predominately in hypersaline water bodies such as inland salt lakes and pans, coastal lagoons, and salt works at salinity levels above 40 g(.)l[superscript(-1)]. They have been extensively studied due to their high monetary value as food for larval fish in aquaculture and their unique reproductive strategies. Brine shrimp occur as either bisexual species or as parthenogenetic populations. Despite ...

A large portion of Canada's reserves of crude oil consists of extra heavy crude and natural bitumens. As the reserves of conventional crude oil continue to decline, heavy oil and bitumen are becoming increasingly important sources of hydrocarbon liquids.
