Adsorption of an anionic surfactant at air-liquid and different solid-liquid interfaces from solutions containing high counter-ion concentration
(
Springer Verlag
, 2015 , Article)
The self-assembly (adsorption) of the anionic surfactant, sodium dodecylbenzenesulphonate (SDBS), at air-liquid and different (octadecanethiol, β-mercaptoethanol, α-lipoic acid) solid-liquid interfaces from aqueous solutions ...
Demulsification of stable emulsions from produced water using a phase separator with inclined parallel arc coalescing plates
(
Elsevier
, 2015 , Article)
A novel and highly efficient oil-water separator equipped with a series of inclined multiple arc coalescence plates is developed and optimized for the removal of stable oil emulsions from produced water. The synthetic high ...
Rheology of a viscoelastic zwitterionic surfactant used in acid stimulation: Effects of surfactant and electrolyte concentration
(
Elsevier
, 2014 , Article)
Acid diversion systems play an important role in increasing the efficiency of the acid stimulation process. Viscoelastic surfactant (VES) based diverting systems have many advantages that make them preferred for well acid ...
Effect of the degree of template removal from mesoporous silicate materials on their adsorption of heavy oil from aqueous solution
(
Springer VerlagHigher Education Press
, 2014 , Article)
The key aim of this study is to evaluate the adsorption of heavy oil from aqueous solutions with different oil contents over mesoporous silicate materials having different surfactant template contents. The mesoporous ...
Self-assembly of a surfactin nanolayer at solid-liquid and air-liquid interfaces
(
Springer Verlag
, 2016 , Article)
Surfactin, a sustainable and environmentally friendly surface active agent, is used as a model to study the adsorption of biosurfactants at hydrophobic and hydrophilic solid–liquid interfaces as well as the air–liquid ...
Polymeric Surfactants and Emerging Alternatives used in the Demulsification of Produced Water: A Review
(
Taylor and Francis Inc.
, 2018 , Article Review)
Stable emulsions are frequently encountered in oil production and cause a series of environmental and operational issues. Chemical demulsification is widely used for the separation of oil from water or removal of water ...
Thermal degradation of aqueous amine/amino acid solutions in the presence and absence of CO 2
(
Institute of Physics Publishing
, 2018 , Conference Paper)
The stability to thermal degradation of aqueous solutions of methyldiethanolamine (MDEA) and their mixtures with glycine (Gly), in the absence and the presence of CO 2 , was investigated by Gas chromatography-flame ionization ...
Investigation of the rheological properties of nanosilica-reinforced polyacrylamide/polyethyleneimine gels for wellbore strengthening at high reservoir temperatures
(
American Chemical Society
, 2019 , Article)
Wellbore strengthening has been introduced recently to resolve lost circulation problems by improving the fracture gradient and hence extending the mud window. Polymeric cross-linkable solutions showed outstanding strength ...
Carbamate Formation and Amine Protonation Constants in 2-Amino-1-Butanol–CO2–H2O System and Their Temperature Dependences
(
Springer New York LLC
, 2018 , Article)
The apparent protonation constant of an amino butanol (AB) and its carbamate formation constant in the CO2–H2O–AB system were determined at T = 298.15–328.15 K, and at various ionic strengths up to 0.2 mol·L−1 by potentiometric ...
Reaction Kinetics of Carbon Dioxide with 2-Amino-1-butanol in Aqueous Solutions Using a Stopped-Flow Technique
(
American Chemical Society
, 2018 , Article)
Carbon capture and management plays an important role in the development of new technologies to mitigate anthropogenic global warming. In this work, for the first time, the kinetics of CO2 with aminobutanol (AB) using a ...
