Designing ionic liquid solvents for carbon capture using property-based visual approach
( Springer Verlag , 2016 , Article)Recently, ionic liquids (ILs) have been introduced as potential carbon dioxide (CO2)-capturing solvents, as a substitute to conventional amine-based solvents. Conventional amine-based solvents that are used for CO2 capture ... -
Designing of polyethylene-based material modified by plasma discharge for water/oil separation
(2021 , Master Thesis)Produced water (PW) from petrochemical industries is one of the largest wastewaters generated in Qatar. Soluble and insoluble oil contaminants occur in this water and must be removed if water will be used or discharged ... -
Designing piezoelectric nanogenerator from PVDFHFP nanocomposite fibers containing cellulose nanocrystals and Fedoped ZnO
( Hamad bin Khalifa University Press (HBKU Press) , 2018 , Conference Paper)Self-powering devices harvest energy from the environment and perform based on a maintenance free approach. These materials are of utmost significance as they solve the problems associated with the energy crisis and ... -
Desorption of chloramphenicol from ordered mesoporous carbon-alginate beads: Effects of operating parameters, and isotherm, kinetics, and regeneration studies
( Elsevier Ltd , 2021 , Article)This study has investigated the desorption of an emerging contaminant, known as chloramphenicol (CPC), from ordered mesoporous carbon (OMC)-alginate beads. The effects of initial concentration, operating temperature, and ... -
Destabilization and treatment of produced water-oil emulsions using anionic polyacrylamide with electrolyate of aluminum sulphate and ferrous sulphate
( Society of Petroleum Engineers , 2016 , Conference Paper)Surfactant and polymer flooding technology can greatly enhance the oil recovery through the expansion of sweeping and displacing efficiency. The recovered oil from surfactant and polymer flooding emulsifies the residual ... -
Destabilization of stable bentonite colloidal suspension using choline chloride based deep eutectic solvent: Optimization study
( Elsevier Ltd , 2021 , Article)Choline chloride (ChCl) based natural deep eutectic solvents (NADES) were synthesized and tested as coagulant for stable bentonite colloidal suspensions. In this work, three ChCl based natural deep eutectic solvent NADES ... -
Destination Competitiveness: The Perceptions of Foreign Tourists Visiting Qatar
( ssrn , 2021 , Article)This paper aims to develop an evidence-based integrated model for destination competitiveness and apply it to the case of Qatar, such that it could be used to identify relevant determinants and rank their contributions to ... -
Desulfurization of the dibenzothiophene ) (DBT) by using -based imidazolium-basedionic ionic i liquids(Ils)
( EnPress Publisher LLC. , 2018 , Article)In this work we have examined the industrial scale extraction process of ultra low sulfur diesel with the help of simulation software ASPEN Plus®.This work focuses on the [Cnmim][BF4](imidazolium-based) ionic liquid and ...
