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…
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…
In this study, industrial-scale reactors are designed and the reactions are numerically simulated by computational fluid dynamics coupled with detailed chemical reaction mechanism. The results show that the mole fraction of C2H2 at the outlet is…
Multiphase flow and complex flow regimes of asphalt-base crude oil with solid-state asphalt and gas presenting in submarine pipelines bring difficulty to the design and operation. For multiphase flow in risers, flow regimes are often very complex. So…
A wide range of proprietary vessel designs are used to carry out chemical reactions. Chemical reactor design must consider the process reaction kinetics, as well as mass transfer, mixing, heat transfer for addition or removal of heat of reaction, and…
Both partial oxidation and CO2 reforming can theoretically be used to produce syngas from natural gas. In this work, the possibility of combining the two methods is explored by the use of computational fluid dynamics with detailed chemical reaction…
Hydrogen can be produced through electrolysis from excess wind and solar power. Then, its injection into the natural gas network allows mitigating the challenges posed by the variability and intermittency of renewables, by exploiting the existing…

Renewable sources and enhancement of energy conversion efficiency are the main paths chosen by the European Community to stop climate changes and environmental degradation, and to enable a sustainable growth. For this purpose, the construction of a…
A wide application of hydrogen energy is seen as a viable strategy to reduce the excessive release of CO2 in the atmosphere. Large demand requires the hydrogen to be distributed through pipelines. While blending hydrogen into existing natural gas…
Synergistic effects of pool fires in fire-induced domino accidents can result in greater damage than single pool fire. Existing research mainly adopts a superposition method based on simplified assumptions to analyze the contribution of synergistic…
Underwater energy storage provides an alternative to conventional underground, tank, and floating storage. This study presents an underwater energy storage accumulator concept and investigates the hydrodynamic characteristics of a full-scale 1000 m3…
One of the big challenges in transporting heavy oils through the pipelines is the high pressure drop due to the effect of viscosity and shear-thinning fluid behaviour of oil. Core annular technique has been applied in industry for transporting heavy…
Transportation of heavy crude oil via pipelines possesses many technological issues that are inherently flow related. Accurate prediction of flow characteristics is an essential step for a reliable piping design of transporting the crude oil. A…
