Cost-effective alkylammonium formate-based protic ionic liquids for methane hydrate inhibition
( Elsevier B.V. , 2018 , Article)In light of current concerns about environmental impact, ionic liquids have been tested in a number of industrial applications, including gas purification, lubrication, and catalysis. In this work, cost-effective ... -
Development of Green Inhibitors to Prevent Hydrates Formation, Protect Environment and Reduce Energy Cost in Oil and Gas Industry
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Gas hydrates are identified as ice-liked solid, crystalline compounds having polyhedral water cavities, where gas molecules get trapped during operation under high pressure and low temperature condition. These hydrates ... -
Doubly dual nature of ammonium-based ionic liquids for methane hydrates probed by rocking-rig assembly
( Royal Society of Chemistry , 2016 , Article)This work presents a systematic study of methane hydrate inhibition in the presence of five structurally variable ionic liquids (ILs) belonging to the ammonium family—viz., tetra-alkylammonium acetate (TMAA), choline ... -
Experimental and DFT Approach on the Determination of Natural Gas Hydrate Equilibrium with the Use of Excess N2 and Choline Chloride Ionic Liquid as an Inhibitor
( American Chemical Society , 2016 , Article)This work presents the characterization of hydrate-forming conditions of a Qatari natural gas-type mixture, QNG-S1, obtained using two different experimental methods, namely, a benchtop reactor and a gas hydrate autoclave. ... -
Gas Hydrate Prevention and Flow Assurance by Using Mixtures of Ionic Liquids and Synergent Compounds: Combined Kinetics and Thermodynamic Approach
( American Chemical Society , 2016 , Article)The thermodynamic and kinetic hydrates inhibition effects of addition of synergents poly(ethylene oxide) (PEO) and vinyl caprolactum (VCAP) with ionic liquids 1-methyl-1-propylpyrrolidinium chloride [PMPy][Cl] and ... -
Gas hydrates inhibition via combined biomolecules and synergistic materials at wide process conditions
( Elsevier B.V. , 2017 , Article)The motive of this research to present a systematic study in context of implementation of gas hydrate inhibitors that are obtained via naturally occurring amino acids (L-Alanine, Glycine, L-Histidine, L-Phenylalanine and ... -
Investigation of the performance of biocompatible gas hydrate inhibitors via combined experimental and DFT methods
( Academic Press , 2017 , Article)In this work, three ionic liquids (ILs) from the bio-compatible family of choline cations attached to anions of varying hydrophobicity namely: choline acetate (ChOAc), choline bistriflamide (ChNtf2), and choline chloride ... -
Probing the effect of various water fractions on methane (CH4) hydrate phase equilibria and hydrate inhibition performance of amino acid L-proline
( Elsevier B.V. , 2021 , Article)To develop an effective hydrate risk mitigation strategy for offshore flow assurance its essential to understand the effect of different water fractions on the rate of hydrate formation and study the effect of various water ... -
Protecting environment and assuring efficient energy transfer using ionic liquids
( Hamad bin Khalifa University Press (HBKU Press) , 2018 , Conference Paper)Gas hydrates are ice-like crystalline compounds that are formed when small gas molecules get trapped within the water molecules under high pressure and low-temperature conditions in oil and gas transmission lines. The ...
