Harvesting the Potential of CO2 before it is Injected into Geological Reservoirsby
![]() ![]() Abstract
To store CO2 in geological reservoirs, expansion valves have been used to intentionally release supercritical CO2 from high-pressure containers at a source point to lower-pressure pipelines and transport to a selected injection site. Using expansion valves, however, has some shortcomings: (i) the fluid potential, in the form of kinetic energy and pressure which can produce mechanical work or electricity, is wasted, and (ii) due to the Joule-Thomson cooling effect, the reduction in the temperature of the released CO [...] 1092 7271 |
Potential of Coupling Heavy Metal (HM) Phytoremediation by Bioenergy Plants and Their Associated HM-Adapted Rhizosphere Microbiota (Arbuscular Mycorrhizal Fungi and Plant Growth Promoting Microbes) for Bioenergy ProductionAbstract
There is growing concern for the contamination of our soils and waters worldwide with heavy metals (HMs), as a result of indiscriminate use of agrochemicals for feeding growing population which require optimal use of resources and sustainable agricultural strategies. This can be simultaneously achieved by using microbes as bio-fertilizers, bio-protectants, and bio-stimulants, and suitable phytoremediation- plant capable of removing heavy metals contaminants from contaminated sites. There is a growing need to adopt [...] 980 7792 |
The Drag Forces on a Taylor Bubble Rising Steadily in Vertical PipesAbstract
By the adoption of a drag-buoyancy equality model, analytical solutions were obtained for the drag coefficients (CD) of Taylor bubbles rising steadily in pipes. The obtained solutions were functions of the geometry of the Taylor bubble and the gas volume fraction. The solutions were applicable at a wide range of Capillary numbers. The solution was validated by comparison with experimental data of other investigators. All derived drag formulas were subject to the condition that Bond number >4, for air-water systems. 938 7057 |
Effect of Mineral Additives on Fusion Behavior of Agricultural Residue Ashes during Combustion or Co-combustion with LigniteAbstract
In this work, the conducted chemical, mineralogical, fusibility, and thermogravimetric analyses and calculated the slagging/fouling indicators for predicting deposition tendencies in boilers to study the ash fusibility behavior of selected agricultural residues and their blends with lignite. Two additives, bauxite, and clinochlore, were used at varying amounts to reduce ash melting, followed by examining their anti-fusion mechanisms. Initial deformation and softening temperatures of biomass materials were low for c [...] 1033 7082 |
Variation of CO2-Brine Contact Angles on Natural Rocks of Different CompositionsAbstract
Contact angles were measured for CO2-brine interactions on 20 different rocks that represent the properties of various CO2 storage depositional environments to characterize the wettability during geologic carbon storage. Three different CO2 phases (gaseous, liquid, and supercritical) were considered to investigate the effect of pressure and temperature. Bubbles were studied in two groups of larger and smaller than 500 μm, the latter being more relevant to pore scale. Variation was observed among contact angle measu [...] 877 7597 |
Hydrogen Storage in Cryogenic, Cybernetic, and Catalytic Vessels for Transport VehiclesAbstract
Most of the hydrogen storage vessels meant for vehicles to run the electric motor via a fuel cell during transport are designed for drives of only a few tenths of kilometers per day. The present report, however, describes a vessel model that is conceived to hold the hydrogen energy only for short periods during transport, such as a few hours. This would include transport via a light-duty vehicle, a taxi, or a bus, which would load liquid hydrogen at a station every morning for the day. This is a simple model based [...] 1059 9927 |
Advances in Wind Farm Layout Optimization: Wind Direction Robustness and Wake Induced Asymmetric Thrust LoadAbstract
In this study, we address the wind farm layout optimization (WFLO) problem and tackle the issue of optimal turbine placement by incorporating additional aspects of an economically driven target function. Firstly, we have analyzed the effect of wind direction on a given turbine arrangement. Based on the direction-dependent wake pattern, practitioners sometimes shut down certain turbines on their farms. Our method computes which turbines should be shut down in which wake situation. On this basis, we have developed a [...] 832 6769 |
Ion Transport in Organic Electrolyte Solutions for Lithium-ion Batteries and Beyondby
![]() ![]() ![]() ![]() ![]() ![]() ![]() Abstract
The performance of metal-ion batteries at low temperatures and their fast charge/discharge rates are determined mainly by the electrolyte (ion) transport. Accurate transport properties must be evaluated for designing and/or optimization of lithium-ion and other metal-ion batteries. In this review, we report and discuss experimental and atomistic computational studies on ion transport, in particular, ion diffusion/dynamics, transference number, and ionic conductivity. Although a large number of studies focusing on l [...] 1849 15226 |
Development of the Flash Ironmaking Technology (FIT) for Green Ironmaking with Low Energy ConsumptionAbstract
This article describes the development of a novel ironmaking technology based on flash reduction. The development started with the proof of the kinetic feasibility, considering that a typical flash reactor provides only a few seconds of residence time. This was followed by tests in a laboratory flash reactor and finally a pilot plant operation. The rate equations formulated in this work were developed considering the optimum combination of temperature, residence time, and reducing gas partial pressure to achieve > [...] 1555 13299 |
