DSC investigation of the gelation kinetics of emulsified PAM/PEI system: Influence of surfactants and retarders
(
Springer Netherlands
, 2015 , Article)
Water production in the oilfields has a negative impact on the production and economy. It is highly desired to shut off water paths without affecting the hydrocarbon zones. Polymer gels are frequently used for water control ...
Synthesis of minimal-size ZnO nanoparticles through sol-gel method: Taguchi design optimisation
(
Elsevier BV
, 2015 , Article)
Zinc oxide (ZnO) has excellent potential to be used in water and wastewater treatment, either as a photocatalyst or in membrane incorporation. In this work, the synthesis of smaller ZnO NPs through a sol-gel approach was ...
Thermochemical treatment of fly ash for synthesis of mesoporous activated carbon
(
Springer Netherlands
, 2015 , Article)
A mesoporous activated carbon is produced from oil fly ash (OFA) using chemical and thermal treatments at different activation conditions. The ash samples were refluxed with a range of compositions of sulfuric, nitric, and ...
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 ...
Optimization of nickel oxide nanoparticle synthesis through the sol-gel method using Box-Behnken design
(
Elsevier BV
, 2015 , Article)
In this study, nickel oxide nanoparticles were prepared using the sol-gel method. The process parameters were optimized to produce smaller size of nanoparticles such as molar ratio, solution pH and calcination temperatures. ...
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 ...
Improving the efficiency of dye sensitized solar cells by TiO2-graphene nanocomposite photoanode
(
Elsevier B.V.
, 2015 , Article)
Nanocomposite photoanodes were prepared by addition of graphene (GR) micro-platelets to TiO2 nanoparticulate paste. TiO2/graphene based DSSCs were fabricated using Z907 photosensitizer. Transmission electron microscope was ...
Rheology of organoclay assisted extrusion of HDPE using Particle Image Velocimetry
(
Institution of Chemical Engineers
, 2015 , Article)
Wall slip is often seen as a source of flow enhancement and can play a significant role during certain melt instabilities in polymer processing. In the present investigation, the effect of organoclay on the wall slip of ...
Rheological characterization of NA2CO3 activated calcium bentonite for oil and gas drilling applications
(
AIChE
, 2015 , Conference Paper)
Calcium bentonite was activated with soda ash (Na2CO3) at various ratios and due to the ion exchange; the original Ca-bentonite was converted to Na-bentonite. It was found that the Na2CO3 activation improves the swelling ...
Electrocoalescence of water drop trains in oil under constant and pulsatile electric fields
(
Institution of Chemical Engineers
, 2015 , Article)
This study addresses the effectiveness of constant and pulsed DC fields in promoting coalescence of dispersed water drops in an oil-continuous phase. For this purpose, a train of drops of relatively uniform size is injected ...
