Increasing worldwide energy demand requires the replacement of fossil fuel sources with clean and alternative ones to limit the chances of a climate collapse. In this scenario, natural gas supplies approximately 30% of total energy demand and is…
The problem of oil spill pollution associated with the transport of crude oil and its products across the globe is of serious concern. The sorption technique has proved to be promising for oil spill treatment but is limited by the hydrophilic nature…
Entropy generation and thermal analysis for freezing process of paraffin within a duct with air turbulent flow have been scrutinized in current article. Unsteady formulation has been utilized with incorporating implicit approach and two dimension…
Underground gas storage (UGS) is a beneficial economic method of compensating for the imbalance between natural gas supply and demand, which is currently considered an important part of the gas chain. To reduce the capital investment of gas storage,…
Asphaltenes represent the heaviest fraction of crude oils, being recognized by their tendency to self-associate and precipitate. Asphaltene precipitation and subsequent deposition can cause problems in all stages of production. The objective of this…
The United States Department of Energy (DOE) manages over 50 Metric Tons Heavy Metal (MTHM) of aluminum-clad spent nuclear fuel. One main source for DOE's Aluminum-clad spent nuclear fuel (ASNF) inventory is the advanced test reactor (ATR) at the INL…
We developed a novel methodology that combines thermo-analytical measurements and mathematical methods to inform the reliable pyrolytic treatment of specific soil/contaminant systems. Our approach improves upon current "black-box" design methods that…
Thermochemical reactions are under investigation for a wide variety of applications. However, the system of two coupled gas-solid reactions exchanging both thermal energy and gas solely with each other has not been investigated yet. This approach…
Because of destructive effects of organic chlorides, elimination of these compounds from contaminated crude oil and its distillates is very crucial for oil refiners. Despite the importance of the subject, limited researches in this field are…
Waxy crude oil emulsions exhibit gelation behavior, with nucleation observed within a certain temperature range. A kinetic model was developed and validated based on the thermal parameters obtained from differential scanning calorimetry cooling…
An emulsion may be classified as a colloidal system depending on the scale analyzed. State parameters (e.g.temperature, volume fraction and osmotic pressure) determine whether the system is regarded as in a liquid-like, liquid/solid-like or…
Several experiments and thermodynamic models are developed to prevent Wax precipitation. Paraffinic hydrocarbons participate to a greater extent in the precipitation process than other hydrocarbon families. However, the existing models do not…
To increase purified gas production and reduce the comprehensive energy consumption of high-sulfur natural gas sweetening units, we established a process simulation model using the ProMax, based on the field operation data of a gas sweetening unit in…
Removing emulsified water from a water-in-crude oil (W/O) emulsion is critically required prior to downstream processing in the petroleum industry. In this work, environmentally friendly and amphipathic rice husk carbon (RHC) demulsifier was prepared…
Remotely located oil fields with high gas-oil ratio and high carbon dioxide content impose challenges for efficient and sustainable gas processing and monetization. This work investigates gas-to-wire coupled to carbon dioxide enhanced oil recovery as…
Crude oil heating is a significant and energy intensive process in crude oil production. Large amounts of heat are required to preheat crude before it processed in a crude distillation unit. This study aims to investigate a novel thermal design for…
