Experimentally measured methane hydrate phase equilibria and ionic liquids inhibition performance in Qatar’s seawater
(
Nature Research
, 2020 , Article)
Qatar has the third-largest natural gas reserves in the world and is the second largest Liquefied natural gas (LNG) exporter in the world. These reserves are mainly located in its offshore North Field where the gas is ...
Density-Functional Theory Investigation of Barite Scale Inhibition Using Phosphonate and Carboxyl-Based Inhibitors
(
American Chemical Society
, 2020 , Article)
Scale deposition is a critical issue in oil and gas exploration and production processes, causing significant blocking in tubing and consequently flow assurance and economic losses. Most studies addressing the scale formation ...

(
Elsevier Ltd
, 2019 , Article)
This work presents a number of integrated strategies aimed at enhancing the performance of the diesel engine and the subsequent reduction of its associated emissions. Three novel spiral-helical shaped intake manifolds with ...
Polymeric adsorbents for oil removal from water
(
Elsevier Ltd
, 2019 , Article)
In this study, the application of four synthetic resins for the removal of emulsified oil from produced water was investigated. Key experimental parameters such as adsorbent dosage, contact time, initial oil concentration ...
Influence of draw solution type and properties on the performance of forward osmosis process: Energy consumption and sustainable water reuse
(
Elsevier Ltd
, 2019 , Article)
Single and multi-component fertilizers were used as a draw solution (DS) in forward osmosis (FO) to produce high-quality water from synthetic and seawater solution, eliminating the need for DS regeneration and reducing the ...
Photocatalytic conversion of CO 2 and H 2 O to useful fuels by nanostructured composite catalysis
(
Elsevier B.V.
, 2019 , Article)
Cu-TiO2 nano-catalysis were successfully prepared using sol-gel method and used for solar photo-reduction of CO2 in gas and liquid phase. Adding Cu to TiO2 matrix modify its crystalline structure, improved its optical ...
Developing ANN-Kriging hybrid model based on process parameters for prediction of mean residence time distribution in twin-screw wet granulation
(
Elsevier B.V.
, 2019 , Article)
Artificial neural network (ANN) modelling is applied to predict the mean residence time of pharmaceutical formulation in a twin-screw granulator. Process parameters including feed flow rate, screw speed, and liquid to solid ...
Bio-carrier and operating temperature effect on ammonia removal from secondary wastewater effluents using moving bed biofilm reactor (MBBR)
(
Elsevier B.V.
, 2019 , Article)
This study investigates the impact of bio-carriers' surface area and shape, wastewater chemistry and operating temperature on ammonia removal from real wastewater effluents using Moving bed biofilm reactors (MBBRs) operated ...
Fabrication and characterization of pyridinium functionalized anion exchange membranes for acid recovery
(
Elsevier B.V.
, 2019 , Article)
In the present work, the fabrication of pyridinium functionalized anion exchange membranes (AEMs) for acid recovery using diffusion dialysis (DD) processes was developed using brominated poly (2,6-dimethyl-1,4-phenylene ...
Molecular Dynamic Simulations of Fibrous Distillation Membranes
(
Elsevier Ltd
, 2018 , Article)
The rate of heat and mass transfer through distillation membranes is typically estimated using an over-simplified, straight-cylindrical-pore approach coupled with several empirical correction factors that are included to ...
