Abstract:

The determination of the NMR spin–spin relaxation rate of water in (purely) aqueous particulate dispersions has been shown to be a convenient and facile experimental approach to probing the composition of near particle surface structures. Here, a systematic study has been undertaken of both non-aqueous and mixed aqueous–non-aqueous solvent particulate dispersions to explore the universality of the solvent relaxation technique. As in the aqueous case, a linear relationship between the surface area present and the solvent relaxation rate is observed, confirming the rapid exchange of the solvent molecules between the surface and the bulk and thereby illustrating the viability of the experimental methodology to study such systems. Crucially, the surface enhancement effect was considerably weaker in non-aqueous systems compared with aqueous dispersions and reflects a potential limitation of the wider deployment of this experimental methodology.

Abstract:

In recent years, new concepts in textile dyeing technology have been investigated which aim to decrease the use of chemicals and the emission of water. In this work, dyeing of cotton textiles with reactive dyes has been investigated in a silicone non-aqueous dyeing system. Compared with conventional aqueous dyeing, almost 100% of reactive dyes can be adsorbed on cotton textiles without using any salts in non-aqueous dyeing systems, and the fixation of dye is also higher (80%~90% for non-aqueous dyeing vs. 40%~50% for traditional dyeing). The pseudo-second-order kinetic model can best describe the adsorption and equilibrium of reactive dyes in the non-aqueous dyeing systems as well as in the traditional water dyeing system. In the non-aqueous dyeing systems, the adsorption equilibrium of reactive dyes can be reached quickly. Particularly in the siloxane non-aqueous dyeing system, the adsorption equilibrium time of reactive dye is only 5–10 min at 25 °C, whereas more time is needed at 60 °C in the water dyeing system. The surface tension of non-aqueous media influences the adsorption rate of dye. The lower the surface tension, the faster the adsorption rate of reactive dye, and the higher the final uptake of dye. As a result, non-aqueous dyeing technology provides an innovative approach to increase dye uptake under a low dyeing temperature, in addition to making large water savings.

Abstract:

gh European energy demands, the difference in prices amongst Europe and ambitious gas producers, have produced a scenario of high competition in a region that suffers a lack of fossil resources still required for energy generation. Therefore, other sources are under the scope of various countries to mitigate these issues. Shale gas is one fuel that presents a scenario that would decrease European dependence on imported gas. Although shale gas production is unlikely to give the energy security desired to the whole Europe, it would make a difference for the communities that will adopt it. However, shale gas has acquired a bad reputation with the public, mainly because of its extraction methods. This bad reputation is attributed to hydraulic fracturing, technology well-known as fracking, and its risks associated towards air and water pollution. Therefore, companies, institutions and governments are looking for other alternative methods of extraction with more environmentally friendly processes. Producing extensive high-pressure pulse waves at the base of the wellbore by using detonation is a promising potential technique for shale gas extraction. A fundamental study of deflagration to detonation transition using recirculated shale gas formation with pure oxygen as an oxidiser has been studied to design a system with lower DDT distance and higher pressure waves. Three proposed cases of UK shale gas composition were studied. Chemical equilibrium software GASEQ and chemical kinetic software CHEMKIN-PRO were used to estimate the product parameters. Results showed that the effect produced by diluents, such as carbon dioxide, are eliminated by the use of higher hydrogen content carbon-to-hydrogen species for the three cases proposed. OpenFOAM CFD was used to calculate the deflagration to detonation transition parameters in stoichiometric hydrogen air mixtures to evaluate different obstacle geometries on the transition phenomenon to improve the detonation process. The shape and layout of obstacles were found to have a significant effect on flame acceleration, and subsequent detonation propagation. The interaction of transverse pressure waves generated at the obstructions governs the propagation mechanism. The transverse waves and its frequency appear to play a pivotal role in supporting the detonation wave. H iv It was found that rectangular shape obstacles reduce the reaction time, while triangular ones achieved detonation with the minimum run-up distance. On the other hand, semicircular shape obstacles generate the highest pressure in a detonation tube. The outcome from numerical calculations and CFD were the guide to construct an experimental rig of 21.2mm diameter and 1500mm length tube with different obstacle configurations to demonstrate the concept of pulse detonation for shale rock cracking. Experimental work has been performed to determine the potential of shale gas production in the Dullais Valley, South of Wales. It was found through several tests using BS standard volatile analyses, Transmission Electron Microscopy and pyrolysis RockEval evaluation that the potential of extraction in this region is fair, with similar concentrations of pyrite but with low energy content compared to those resources located in the Midlands and Yorkshire. However, the use of controlled pulse detonation could be the ideal technology for extraction in Wales, as low sulphur (S) content will produce lower unwanted emissions, with a process that can promote opening of pores and further gasification of oil based molecular, with a subsequent increase in shale gas production, topic that requires further research. Finally, a 2-dimensional simulation was performed using ANSYS Parameter Design Language (APDL) to investigate the effect of pressure pulse generated by the detonation tube on a pre-crack. Results showed that the layer close to the applied load will be displaced, which means that it will be smashed. The maximum Von Mises stresses were found to concentrate at the perforating hole corners, while the region immediately after the crack tip is susceptible to compression stresses. The Same behaviour was found for the stress intensity factor. According to that, it is believed that the cracks will propagate diagonally from the perforating hole base. Therefore, the current work has theoretically demonstrated the technology for shale gas recovery, with an optimised geometry consistent of internal obstacles, for a region with potential for shale gas exploitation.

Abstract:

Non-aqueous wax/solvent systems of industrial relevance for the manufacture of paste polishes have been investigated. These mixtures have been modelled using a paraffin wax of Japanese origin (Nippon Seiro 140/145°F) in a solution of pure heptane to which dopant components are added.The stability of any resulting gel has been assessed via solubility studies and measurement of the solvent vapour pressure. A new technique for the measurement of vapour pressure in these systems has been developed. The operation of the apparatus has been made almost completely automatic by the use of modern control units.Complementary analytical techniques such as Differential Scanning Calorimetry and Nuclear Magnetic Resonance have been used to augment the data where appropriate and the structure of these pastes has been investigated with the use of Optical Microscopy.

Abstract:

Magnetite, an iron oxide, is a possible candidate for in situ remediation of contaminated groundwater systems due to its oxidation/reduction potential for reduction of contaminants such as carbon tetrachloride. Little characterization and analysis has been done to describe the kinetics of magnetite transformation during oxidation. This work focuses on monitoring the concentrations of magnetite and one of its oxidation transformation products, maghemite, by the use of UV-Vis-NIR spectroscopy. As oxidation proceeded at a constant specific temperature, the concentration of magnetite decreases, which was indicated by a decrease in absorption in the NIR-region of the spectrum. As magnetite concentrations decreased, the concentration of maghemite increased, which was indicated by an increase in absorption in the UV-region. The temperature at which the suspensions of magnetite and maghemite were measured was of great importance for complete understanding of the magnetite transformation as seen by UV-Vis-NIR spectroscopy analysis. Higher measurement temperatures produced higher absorptivities of FeII-FeIII electron hopping transitions, while decreasing the absorptivity of FeIII-FeIII in the NIR and UV-regions respectively. Lower temperatures produced the opposite effects on the iron oxidesâ transitions. Higher temperature increased the rate of oxidation.

Abstract:

Abstract Foam flooding is a crucial enhanced oil recovery technique for profile control during the oil displacement process. The stability of the foam is the key factor for the success of foam flooding, but typical aqueous foams generally lose their stability in the presence of hydrocarbons because of their low oil tolerance. Non-aqueous foams possess outstanding stability in the presence of hydrocarbons as a result of their unique properties. However, few studies have been conducted on the stabilization mechanisms of non-aqueous foams in the presence of hydrocarbons. In this study, comparative experiments were performed to investigate differences in the stabilization mechanism between aqueous and non-aqueous foams. The results showed that a non-aqueous foam had excellent oil tolerance in a bulk foaming test. Then, the stabilization mechanisms of foams were investigated in terms of surface dilatational viscoelasticity and liquid film thinning. For a non-aqueous foam system, the maximum viscoelastic modulus of 55 mN/m occurred at a surfactant concentration of 5.0 wt%, which indicated that the foam was more stable. In a foam film thinning experiment, the thinning time of an aqueous foam system was shortened but the liquid film thickness was increased by crude oil, whereas crude oil increased the thinning time of a non-aqueous foam system but decreased its liquid film thickness. In a non-aqueous foam system, the film could remain stable for hours before rupturing, which indicated that its stability in the presence of an oil phase was excellent. These results are meaningful for the understanding of the stabilization mechanisms of oil-based foams and the employment of non-aqueous foams for enhanced oil recovery.

Abstract:

Recent advent of Aqueous-Two-Phase-System (ATPS), more biologically friendly compared to conventional oil-water systems, has shown great potential to rapidly generate aqueous droplets without tedious post-processing. However, understanding of underlying physics of droplet formation in ATPS is still in its infancy. In this paper, we investigate hydrodynamic behaviors and mechanisms of all-aqueous droplet formation in two flow-focusing droplet generators. Two incompatible polymers namely polyethylene glycol (PEG) and dextran (DEX) are mixed in water to make ATPS. The influence of inlet pressures and flow-focusing configurations on droplet sizes, and thread breakup length is studied. Flow regime mapping for two different configurations of droplet generators possessing junction angles of 30° and 90° is also obtained. The results show that droplet size is very susceptible to the junction angle while inlet pressures of the PEG and DEX flows readily control four main flow regimes including back flow, dripping, jetting and stratified.

Abstract:

The Montney Formation in Alberta and British Columbia, Canada is an early Triassic siltstone currently in an active diagenetic environment at depths greater than 1,000 m, but with maximum burial depths potentially exceeding 5,000 m (Ness, 2001). It has undergone multiple phases of burial and uplift and there is strong evidence for multiple generations of hydrocarbon maturation/migration. Understanding the origin and history of diagenetic fluids within these systems helps to unravel the chemical changes that have occurred since deposition. Many cores taken near the deformation front display abundant calcite-filled fractures including vertical or sub-vertical, bedding plane parallel (beefs), and brecciated horizons with complex mixtures of vertical and horizontal components. We analyzed vertical and brecciated horizons to assess the timing and origin of fluid flow and its implications for diagenetic history of the Montney Fm. Aqueous and petroleum bearing fluid inclusions were observed in both vertical and brecciated zones; however, they did not occur in the same fluid inclusion assemblages. Petroleum inclusions occur as secondary fluid inclusions (e.g. in healed fractures and along cleavage planes) alongside primary aqueous inclusions indicating petroleum inclusions post-date aqueous inclusions and suggest multiple phases of fluid flow is recorded within these fractures. Raman spectroscopy of aqueous inclusions also display no evidence of petroleum compounds supporting the absence or low abundance of petroleum fluids during the formation of aqueous fluid inclusions. Pressure-corrected trapping temperatures (&gt;140°C) are likely associated with the period of maximum burial during the Laramide orogeny based on burial history modelling. Ice melt temperatures of aqueous fluid inclusions are consistent with 19% NaCl equiv. brine and eutectic temperatures (-51°C) indicate NaCl-CaCl2 composition. Combined use of aqueous and petroleum fluid inclusions in deeply buried sedimentary systems offers a promising tool for better understanding the diagenetic fluid history and helps constrain the pressure-temperature history important for characterizing economically important geologic formations.
