Amir H. Mohammadi, Auteur ; Veronica Belandria, Auteur ; Dominique Richon, Auteur |In this communication, we examine the possibility of clathrate hydrate formation of toluene and o-, m-, or p-xylene with methane as help gas. An isochoric pressure-search method was used to measure hydrate phase equilibrium boundaries. The relia[...]

Ali Eslamimanesh, Auteur ; Amir H. Mohammadi, Auteur |Glycols are generally used to adjust the water dew-point in natural gas processes to avoid gas hydrate/ice/condensate formation. Their vaporization loss in gaseous systems may happen regularly in the petroleum industry. Glycols have very low sol[...]

Ali Eslamimanesh, Auteur ; Amir H. Mohammadi, Auteur ; Dominique Richon, Auteur |Accurate knowledge of the sulfur content of gases is a significant factor for prediction of the sulfur precipitation conditions in production of sour natural gases. However, because the concentration of sulfur in the gas phase is very low, the m[...]

Amir H. Mohammadi, Auteur ; Dominique Richon, Auteur |In this communication, we report an artificial neural network algorithm for estimating sulfur content of hydrogen sulfide at elevated temperatures and pressures. This model eliminates any need for characterization parameters, due to the tendency[...]

Ali Eslamimanesh, Auteur ; Saeedeh Babaee, Auteur ; Amir H. Mohammadi, Auteur |Accurate knowledge of the compositions of the equilibrium phases in the systems containing gas hydrates is essential for many hydrate-based separation processes. Unfortunately, there are limited sets of such experimental data available in the li[...]

Mehdi Mehrpooya, Auteur ; Amir H. Mohammadi, Auteur ; Dominique Richon, Auteur |In this communication, we report an extended artificial neural network algorithm to estimate sulfur content of sour/acid gases. The main advantage of this algorithm is that it eliminates any need for characterization parameters, due to the tende[...]

Amir H. Mohammadi, Auteur ; Ali Eslamimanesh, Auteur ; Dominique Richon, Auteur |In this paper, we present two different approaches to represent/predict the gas hydrate phase equilibria for the carbon dioxide, methane, or ethane + pure water system in the presence of various types of porous media with different pore sizes. T[...]

Amir H. Mohammadi, Auteur ; Dominique Richon, Auteur |In this work, we report ice−clathrate hydrate−gas equilibrium data (dissociation data) for the air, oxygen, nitrogen, carbon monoxide, methane, or ethane + water system. The equilibrium data for methane and ethane clathrate hydrates are compared[...]

Amir H. Mohammadi, Auteur ; Dominique Richon, Auteur |In this communication, we report ice―clathrate hydrate―gas equilibrium data (dissociation data) for the argon + water and carbon dioxide + water systems in the temperature ranges of (264.3―271.2) and (260.2―270.7) K, respectively. The equilibriu[...]
