Abstract:

The flow of particulate suspensions and brines in porous media is encountered in a wide range of industrial situations such as oil production, soil erosion, and ground water pollution and in the operation of filter beds. Three major classes of such problems are addressed in this thesis, namely particle movement, scale formation and filtration. Particle movement and scale formation are known to be serious problems in oil reservoirs where incompatible brine is brought into contact with the formation. Dramatic reductions in permeability are observed in such cases due to the release of fine partic

Abstract:

Concerns over the environmental impact of carbon dioxide (CO2) have led to a resurgence of interest in CO2 injection (CO2I) in oil reservoirs, which can enhance oil recovery from these reservoirs and store large quantities of CO2 for a long period of time. Oil displacement and recovery by CO2I has been studied and applied in the field extensively. However, CO2I lacks acceptable sweep efficiency, due to the large viscosity contrast between CO2 and resident reservoir fluids. Various CO2I strategies e.g. alternating (WAG) or simultaneous injection of CO2 and water have been suggested to alleviate

Abstract:

In recent years, oil shale has attracted renewed attention as an unconventional energy resource, with vast and largely untapped reserves. Oil shale is a fine-grained sedimentary rock containing a sufficiently high content of immature organic matter from which shale oil and combustible gas can be extracted through pyrolysis. Several complex physical and chemical changes occur during the pyrolysis of oil shale where macromolecular network structures of kerogen are thermally decomposed. The pyrolysis of oil shale leads to the formation of a microscopic pore network in which the oil and gas produc

Abstract:

Surfactant enhanced oil recovery (EOR) is used to increase production from oil reservoirs where, after conventional water-flooding processes, typically 60-70% of oil remains trapped by capillary forces. Enhanced recovery processes are important because of the reduction of easily accessible new reservoirs and increasing global demand for energy. This thesis describes studies on the visualisation of the oil-water interface during surfactant flooding enabling investigation of the underpinning mechanisms of surfactant EOR. The results will aid design systems for more efficient oil recovery and imp

Abstract:

Fouling is a complex phenomenon which commonly occurs in crude oil heat transfer equipment, reducing heat transfer, increasing pressure drops and in general resulting in reduced energy recovery efficiency and increased capital and operating costs of refineries. Measuring with accuracy the fouling behaviour of an oil at or close to industrial conditions is not easy. A High Pressure Oil Rig (HIPOR), designed to overcome current limitations and operate in a regime close to refinery heat and tube exchangers, has been developed at Imperial College under the direction of Prof. G.F.

Abstract:

The prediction of residual oil saturation (Sor) and relative permeabilities after waterflooding in mixed-wet systems is a very challenging task. These are important parameters which must be estimated for a full field simulation of waterflooding. The Sor also defines the target oil for any proposed EOR process after an initial waterflood. Pore-scale network modelling can be used to estimate relative permeabilities, and the amount and nature of the trapped residual oil if the correct physics of oil displacement are properly included. During the waterflooding of mixed-wet systems, oil may drain d

Novel epoxidized sucrose soyate (ESS) resins perform much better than other vegetable oil-based resins; thus, they are of current interest for commercial scale production and for a wide range of applications in coatings and polymeric materials.

To achieve this goal, canola oil was first epoxidized at a 300 g scale to study the epoxidation rate and thermal profile at different hydrogen peroxide (H2O2) addition rates, bath temperatures, and reaction times.

Carbon geosequestration (CGS) has been recognized as a strategic solution to prevent/counter the catastrophic consequences of climate change.

Furthermore, combining carbon geosequestration with Enhanced Oil Recovery (EOR) is an efficient and economically a

Abstract:

Over the course of normal oil well operations, pipes used downhole in the oil and petroleum industry tend to accumulate a mineral deposit on their interior, which restricts the flow of oil. This deposit, termed scale, will eventually occlude the interior diameter of the pipe making removal from service and descaling a cost effective option. The pipes are sent to cleaning yards where they remain until descaling can be performed. This storage period can potentially create a health concern not only because of the external radiation exposure but also because of the radon gas emissions, both of

Abstract:

Geologic CO2 storage has been identified as key to avoiding dangerous climate change. Carbon dioxide is also injected into oil fields to enhance oil recovery (EOR). The aim of EOR is to enhance recovery by reducing the residual or remaining oil inside the pore space of reservoir rocks while the aim of carbon storage is to maximize CO2 trapping. The processes governing trapping are fundamentally rooted in the wettability or capillarity of the system. The wettability of CO2-brine-rock systems will have a major impact on the management of carbon sequestration in subsurface geological formations.

Carbon dioxide corrosion, which can cause premature failure of oil and gas pipelines, is an imperative health, safety and environmental issue in the oil and gas industry.

This scale can be protective toward the carbon steel pipelines.

Abstract:

The last couple of decades have seen entrained-flow gasification of black liquor (BL) undergo an incremental process of technical development as an alternative to combustion in a recovery boiler. The ability of the technology to combine chemical recovery with the production of clean syngas renders it a promising candidate for the transformation of chemical pulp mills into integrated forest biorefineries. However, techno-economic assessments have shown that blending BL with the more easily transportable pyrolysis oil (PO) can not only increase the system efficiency for methanol production but r

Abstract:

The palm oil processing industry in Ghana is dominated by informal small-scale mills. However, the waste management of the informal mills have received little attention in research. The aim of this research was to determine the sources and quantity of water used, quantity and quality of wastewater produced to guide sustainable management of the wastewater. Twenty-five mills were selected for assessing the water sources and quantities, wastewater quantities and disposal practices. Wastewater samples were collected from four of the processing mills in both lean and peak production seasons for ch

Abstract:

Research on the electrocoagulation (EC) of hexane extractable materials (HEM) has been conducted at the University of New Orleans using a proprietary bench-scale EC reactor. The original reactor configuration forced the fluid to follow a vertical upward-downward path. An alternate electrode arrangement was introduced so that the path of flow became horizontal. Both configurations were evaluated by comparing the residence time distribution (RTD) data generated in each case. These data produced indication of internal recirculation and stagnant water when the fluid followed a vertical path. These

Abstract:

The rapid expansion of oil palm cultivation in Southeast Asia raises environmental concerns. Oil palm growers in Indonesia are faced with the challenge of sustaining high yields to keep pace with the growing global demand for oil and fats, while reducing the environmental impacts of oil palm cultivation. Environmental impacts associated with the deforestation at the initial phase of an oil palm plantation establishment are well documented, however the impacts of mature oil palm plantation on water quality remain poorly investigated. Oil palm is a perennial crop cultivated predominantly on wea
