Iron Sulfide Scale Inhibition in Carbonate Reservoirs
(
American Chemical Society
, 2022 , Article)
Hydrocarbon production operations include water injection, varying stimulation approaches, and enhanced oil recovery techniques. These treatments often affect reservoir formation, production, and injection facilities. Such ...
Pilot-scale study on the suspension of drill cuttings: Effect of fiber and fluid characteristics
(
Elsevier
, 2022 , Article)
Drilling operation smoothness is essential to minimize drilling non-productive time (NPT). Inadequate cuttings transport can result in cuttings bed build-up in the wellbore low side, jeopardizing the whole drilling operation. ...
A reservoir bubble point pressure prediction model using the Adaptive Neuro-Fuzzy Inference System (ANFIS) technique with trend analysis
(
Public Library of Science
, 2022 , Article)
The bubble point pressure (Pb) could be obtained from pressure-volume-temperature (PVT) measurements; nonetheless, these measurements have drawbacks such as time, cost, and difficulties associated with conducting experiments ...
The impact of mechanically-imposed shear on clogging, fouling and energy demand for an immersed membrane bioreactor
(
MDPIAG
, 2018 , Article)
The impact of the application of mechanically-imposed shear on the propensity for fouling and clogging (or “sludging”—the agglomeration of sludge solids in the membrane channel) of an immersed flat sheet (iFS) membrane ...
Decoration of polylactic acid on graphene oxide for efficient adsorption of methylene blue and tetracycline
(
Elsevier Ltd
, 2023 , Article)
Decorating nanomaterials on graphene oxide (GO) can enhance its adsorption capacity and removal efficiency of water pollutants. In this study, for the first time, nano-sized polylactic acid (PLA) has been successfully ...
The emergence of multifunctional adsorbents and their role in environmental remediation
(
Elsevier Ltd
, 2021 , Article)
Water pollution is a growing issue which requires various treatment technologies for efficient and effective remediation. Adsorption is one of the dominant wastewater treatment technologies due to its flexible operation ...
Optimization of the Biotreatment of GTL Process Water Using Pseudomonas aeruginosa Immobilized in PVA Hydrogel
(
MDPI
, 2022 , Article)
The COD reduction in gas to liquid (GTL) process water was optimized using response surface methodology (RSM). The biodegradation process was carried out in a spouted bed bioreactor (SBBR) using Pseudomonas aeruginosa ...
Synergistic effect of Cu2+ in Fe2+/H2O2 reaction system to enhance oxytetracycline degradation in polluted water
(
Institute for Ionics
, 2023 , Article)
The higher production of HO· concentration associated with the presence of a Cu2+ co-catalyst in a Fe2+/H2O2 system is reported. The synergistic effect of the co-catalyst was investigated to evaluate the possibility of ...
Optimizing and control of effective synthesize parameters for Fe3O4 nanoparticles using response surface methodology
(
Springer Science and Business Media Deutschland GmbH
, 2022 , Article)
To control Fe3O4 nanoparticles (Fe3O4 NPs) size, different molar ratio of Fe2+ and Fe3+ as well as ammonium hydroxide (pH) was used to synthesize Fe3O4 NPs through co-precipitation method. The Box–Behnken design was selected ...
Simultaneous removal of Congo red and cadmium (II) from aqueous solutions using graphene oxide–silica composite as a multifunctional adsorbent
(
Chinese Academy of Sciences
, 2020 , Article)
Graphene oxide is a very high capacity adsorbent due to its functional groups and π−π interactions with other compounds. Adsorption capacity of graphene oxide, however, can be further enhanced by having synergistic effects ...
