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 ...
Optimization of selection of chain amine scrubbers for CO2 capture
(
Springer Verlag
, 2014 , Article)
In order to optimize the selection of a suitable amine molecule for CO2 scrubbers, a series of ab initio calculations were performed at the B3LYP/6-31+G(d,p) level of theory. Diethylenetriamine was used as a simple chain ...
Experimental and theoretical studies on the mechanical and structural changes imposed by the variation of clay loading on poly(vinyl alcohol)/cloisite 93A nanocomposites
(
John Wiley and Sons Ltd
, 2019 , Article)
Polymer nanocomposites (PNC) structures are promising materials due to their novel properties. However, many of their characteristic physical, mechanical, and chemical behavior have not been quantified. Depending on the ...
Catalytic evaluation of nickel nanoparticles in methane steam reforming
(
Elsevier
, 2016 , Article)
Development of a highly efficient and coke-resistant, nickel nanoparticles (Ni.NPs) based catalyst in the steam reformation reaction of methane is reported. The catalyst was prepared by dispersing Ni-nanoparticles over ...
Petroleum refinery wastewater treatment: A pilot scale study
(
Elsevier
, 2016 , Article)
A three-step pilot plant was designed, fabricated and tested for the treatment of highly contaminated petroleum refinery wastewater. The three-step process consisted of an electrocoagulation (EC) unit, a biological treatment ...
The status of industrial and municipal effluent treatment with membrane bioreactor technology
(
Elsevier
, 2016 , Article)
The status of MBR technology has been scrutinised with reference to (a) available commercial technologies and their characteristics, (b) key design and performance parameters of existing full-scale installations, and (c) ...
Simulation study of Schottky contact based single Si wire solar cell
(
IEEE
, 2014 , Conference Paper)
We model single silicon nanowire (SiNW) solar cells with dissimilar work function metal contacts. Both short circuit current (ISC) and open circuit voltage (VOC) have been investigated. Effects of nanowire dimension, ...
Enhancing gas loading and reducing energy consumption in acid gas removal systems: A simulation study based on real NGL plant data
(
Elsevier B.V.
, 2018 , Article)
© 2017 Elsevier B.V. Amine scrubbing with absorption and desorption is the most established technology for Acid Gas Removal (AGR) systems, but suffers from high regeneration energy requirements and, hence offers a good ...
How the activation process modifies the hydrogen storage behavior of biomass-derived activated carbons
(
Springer US
, 2017 , Article)
Microporous activated carbons (ACs) derived from biomass residues, by virtue of their low-cost, good thermo-mechanical stability and easy adsorbent regeneration, are widely considered as hydrogen storage materials for ...
