Clathrate hydrates are non-stoichiometric, ice-like crystalline solids that can lead to plugging of crude oil pipelines. In addition, wax deposition leads partial or complete blockage Crude is a complex hydrocarbon mixture includes asphaltenes, aromatics, naphthenes, resins, and paraffins. Deconvoluting the effects solid particles surfactants present in on hydrate formation would improve prediction strategies. A fundamental investigation using model was carried out (i) deconvolute effect...
Efficient phase separation of oil and water in emulsions is critical for treatment hydrocarbon processing. Our research aims at elucidating the water-in-oil using silica nanoparticles (SNPs). By probing surfactant–nanoparticle interactions, we show that surfactant-stabilized can be destabilized depending on nanoparticle wettability mode addition. The efficiency to demulsify depended both surfactant concentration. Water-in-oil were when partially hydrophobic added emulsion after formation...
High fidelity, three-dimensional CFD was used to model the flow, fuel injection, combustion, and emissions in a large bore medium speed diesel engine with different levels of natural gas substitution. Detailed chemical kinetics complex combustion behavior premixed gas, ignited via spray. The numerical predictions were compared against measured multiple cycle pressure data, understand possible factors affecting cyclic variation experimental data. Under conditions high substitution rates,...
Abstract An extensive experimental study of ethane oxidation and pyrolysis has been conducted in the high pressure shock tube at UIC covering reflected pressures from 5–1000 bar, reaction temperatures up to 1550 K stoichiometric (Φ = 1), fuel rich 5), pyrolytic mixtures. The data used develop a single model that can simulate whole dataset very well is first capable simulating results over such an range pressure, temperature, stoichiometry. © 2005 Wiley Periodicals, Inc.

In the petroleum industry, emulsions are encountered in nearly every stage of oil production, transportation, and operation. An understanding mass transfer rates during gas evolution from supersaturated solutions is critical for enabling better design operation gas–liquid separators. The objective this work was to elucidate influence surfactant water droplet sizes present water-in-oil on rate (volumetric coefficient) systems. volumetric coefficient at elevated pressure (3.45 ± 0.00689 MPa)...
The rate of gas evolution (volumetric mass transfer coefficient) is a critical parameter in understanding and predicting gas–liquid separation, especially the energy industry. This work led to development an empirical correlation determine coefficient based on dead oil properties dissipation. approach was evaluated using published n-dodecane data. tested for model crude oils experimental data absorption under varying levels dissipation from liquids viscosities. dissipated liquid varied by...
There is a need to better understand the mechanisms that govern gas evolution (i.e., desorption) from supersaturated solutions at elevated pressures for improved design and troubleshooting of gas–liquid separators used in oil industry. The rate generally represented terms mass transfer coefficient, which can be affected by presence chemical additives. In industry, wide variety additives are used, such as demulsifiers, antifoamers, corrosion inhibitors. Two different classes were evaluated...
