Carbon dioxide is produced from the combustion of fossil fuels and as a by-product of many chemical processes. The increasing concentration of CO2 in the atmosphere has now been decisively linked to global climate change. The use CO2 as a carbon-building block has attracted much attention due to its low cost, ease availability, and its potential to substitute fossil fuel-based feedstocks, in addition to the clear positive environmental effect of removing it from the atmosphere.
Tungsten carbide-based coatings are used to protect oil field equipment from wear and corrosion. The coatings are carbide-metal composites and are applied by a spraying process. By applying the coatings it is possible to extend the lifetimes of critical equipment such as pumps and valves, and avoid unplanned outages. The spraying process used to deposit the coatings produces a substantial amount of waste powder . This project will design a method to recycle the scrap powders to enable them to be used to produce industrial -quality protective coatings.
In the upstream pipelines, the application of the internal pipeline coatings with specialized polymer has been utilized to protect pipeline from corrosion and abrasive wears. The coatings are rearranged or re-lined when the coating wears out. However, there is no direct and continuous monitoring for the integrity of internal pipeline coatings. Thus the rearrangement or re-lining of the coating is performed pre-emptively before fully utilizing the coating. It is required to develop a novel technique, not only for the efficiency but also to prevent pipeline leakage.
In an effort to ensure pipelines continue to operate in a safe condition, various inspections and assessments are completed on a continual basis during their operating lifespan. These assessments include radiographic or ultrasonic examinations, forms of non-destructive examination (NDE), of circumferential girth welds formed between multiple pipe sections.
Recent pipeline projects in Canada and the US have attracted lots of attention due to their importance for our future economy and environment. In the proposed project University of Alberta and Shawcor propose to work together towards developing E-smart pipelines and creating defect free system. We will utilize the vast amount of emerging and cutting-edge technical know-how in wireless technologies and apply that for the benefit of our energy and environmental sectors. Such information provides the opportunity to intelligently develop defect free pipeline.
Phytoremediation (plant-based environmental cleanup) is a green, cost-effective alternative to conventional methods for contaminated site cleanup, which often involve extensive, community-disruptive, industrial efforts. Deep-rooted trees, such as hybrid Canadian poplars, can effectively be used to contain and clean up petroleum-derived contaminants in soil and groundwater resources.
The use of natural gas as a fuel for on-road commercial vehicles offers significant benefits, including lower greenhouse gas emissions. Methane, the main component of natural gas, has many virtues as a fuel. One of these benefits is that it is a very stable molecule. This stability does introduce a challenge: it is hard to remove from the exhaust stream any methane that isnt consumed in the engine. This internship will help to address this factor, focusing on using a catalytic reactor in the exhaust of an engine.
Transportation of oil and gas through pipeline networks remain a crucial infrastructure for sustainable economic growth in Canada. Pipeline wear and damage will remain a major concern as it can lead to catastrophic failures causing environmental and economic damage if undetected. For easier detection of damage on a large network of pipelines, an array of wireless radio frequency identification tags was developed for steel pipes. However, the material used for the tags were not suitable for pipes made with polymer composites as the stiffness of the copper could damage it.
Sand production during extraction of bitumen in oil sand industry is the most significant challenge which results in many operational problems such as erosion of downhole and surface equipment, collapse of the formation, and subsequently a dramatic increase in capital and operating costs of the production plant. Mesh weaves are currently used to reject sand during production and mitigate these effects. The proposed research project will investigate the flow, and solid retention capacity of different mesh weaves in various test cells.
In this project, we develop a framework to use the data from fiber sensing technologies to smart monitoring of Oil and Gas Reservoirs. The project involves extensive lab experiments simulating different monitoring conditions. Different configurations for installation of sensing equipment will be examined. The optimum location of tubing will be also determined. Signal processing methods will be used to extract useful information from the raw fiber-sensed data. Through experiments, we will record and analyze the relationship of fiber-sensed signals and the flow conditions.
