Dispersion of asphaltene in crude oil using ionic liquids (ILs) is being considered as a viable solution, in extraction and transportation processes. In this work, the interplay between asphaltene and ILs has been studied systematically to understand…
Recently, global attraction has shifted toward heavy unconventional crude oil due to the depletion of light oil resources. Generally, heavy crude oils are highly viscous in nature
Rail incidents involving release of crude oil from train tank cars is a safety concern. The objectives of this study are identification and quantification of the impacts of different factors on types and consequences of crude oil release from trains,…
An accidental leakage of Liquefied Natural Gas (LNG) can occur during processes of production, storage and transportation. LNG has a complex dispersion characteristic after release into the atmosphere. This complex behaviour demands a detailed…
With the rapid industrialization and urbanization in China, underground tunnels, as an effective way to construct and maintain energy supplies, have been widely utilized to transport natural gas in urban chemical plants and industrial parks. Natural…
Corrosivity of petroleum fractions with the same total acid value (TAN) can be much different due to chemical structure differences of acidic species. To investigate corrosivity difference and interactions between different acidic species, acids with…
During accidental crude oil spills and permitted discharges of produced water into the marine environment, a large fraction of naturally occurring oil components will be contained in micron-sized oil droplets. Toxicity is assumed to be associated…
CO2 sequestration with enhanced gas recovery (CO2-EGR) is a promising technology, especially in the case of re-injecting the separated CO2 from natural gas into the same gas reservoir. The description of dispersion between these two gases benefits…
As waxy crude oil comes to the surface, it will cool down and causing the waxy fraction to gel. The gelled crude chokes the well, leading to restricted or blocked production and costly downtime for operators. One of the most common chemical solutions…
There are many people in urban construction areas, and natural gas leakage can potentially cause serious accident consequences. Predicting the consequences of gas dispersion is important to react rapidly and adequately in the event of an incident.…
In this article T1 dispersion measurements on a set of crude oils that span a viscosity range of 0.7 cP up to 2·104 cP are reported. Larmor frequencies were varied from 10 kHz up to 20 MHz. The relaxation dispersion measurements are interpreted in…
Precipitation of asphaltenes in oil fields represents interfacial phenomena of great concern for oil industry. Oil production decreases due to the obstruction of reservoir rock pores by asphaltene blockage. Futhermore, the phenomena of wettability…
As a complex mixture, high-hydrogen-sulfide natural gas has a high risk of poisoning and explosions after leakage. This study combined wind tunnel experiments, computational fluid dynamics (CFD) technology, and risk theory to explore the dispersion…
The dispersion coefficient is a key physical parameter for enhanced gas recovery (EGR) and reflects the degree of mixing between the displacing-fluid CO2 and natural gas. However, no comprehensive overview of existing research on EGR dispersion…
Production from highly paraffinic crude oil wells poses unique technical challenges such as poor flowability and paraffin deposition on the production tubing. Paraffin deposition increases the lift load on the pump, reduces pump efficiency, and…
Accidental leakages in underwater natural gas pipelines pose significant risks for the environment. Therefore, it is essential to estimate the leakage rate and monitor the methane diffusion range outside the pipeline, which is challengeable due to…
The methane into the soil from buried natural gas pipelines due to small leakages, changes the soil properties, posing potential risks to humans and the environment. It is essential to estimate the leakage rate and monitor the methane diffusion range…
