Hydrogen sulfide (h2s) leakage and dispersion from a sulfide recycle installation in different wind speeds are simulated by implementing a 3D Computational Fluid Dynamics (CFD) model. h2s concentrations of monitor points which represent dispersion…
In CO2 enhanced gas recovery (EGR), physical dispersion occurs between CO2 and natural gas, which can pollute the produced natural gas. Therefore, accurate assessment of the dispersion process is important for the commercialization of EGR. Under…
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…
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…
Despite the numerous works devoted to using of different types of nanoparticles for treatment of asphaltene related issues, the potential applications of carbon nanostructures for controlling of asphaltene precipitation have not been addressed in the…
Amplitude-versus-offset (AVO) inversion always plays an important role in reservoir fluid identification, which allows the estimation of various rock and fluid properties from prestack seismic data. In this paper, we propose a new method for…
In seismic exploration, the wavelet-filtering effect and Q-filtering (amplitude attenuation and velocity dispersion) effect blur the reflection image of subsurface layers. Therefore, both wavelet- and Q-filtering effects should be reduced to retrieve…
In mineral transportations, it is essential to measure the gas hydrate particle concentration to manage the risk of flowline blockage. Traditional single-frequency ultrasonic methods measure the particle concentration by treating the mixtures with an…
Present work aims to predict the explosion characteristics of LNG (Liquefied Natural Gas)-air clouds in a model receiving terminal. Due to the limitations in integral/phenomenological models to include the higher cloud density effects, different…
Compared to liquid/gas hydrogen tank, the pipeline is an economical way for hydrogen transportation. With the quick development of utility tunnel in China, hydrogen pipeline enters the gas compartment can be expected soon. However, all the safety…
CO2 emission mitigation is one of the most critical research frontiers. As a promising option of carbon capture, utilization and storage (CCUS), CO2 storage with enhanced gas recovery (CSEGR) can reduce CO2 emission by sequestrating it into gas…
This work was focused on the characterization of flash fire scenarios resulting from the accidental release of liquefied natural gas (LNG) by keeping into account vapour stratification and temperature gradient, which deeply modify the combustion…
