Doubly dual nature of ammonium-based ionic liquids for methane hydrates probed by rocking-rig assembly
(
Royal Society of Chemistry
, 2016 , Article)
This work presents a systematic study of methane hydrate inhibition in the presence of five structurally variable ionic liquids (ILs) belonging to the ammonium family—viz., tetra-alkylammonium acetate (TMAA), choline ...
Highly selective CO2 removal for one-step liquefied natural gas processing by physisorbents
(
Royal Society of Chemistry
, 2019 , Article)
Industrial specifications require CO2 concentrations in natural gas below 50 ppm during liquefaction because of corrosion and CO2 freezing. Herein, we report a physisorbent (TIFSIX-3-Ni) that exhibits new benchmark CO2/CH4 ...
Impact of temperature and storage time on the migration of antimony from polyethylene terephthalate (PET) containers into bottled water in Qatar
(
Springer International Publishing
, 2017 , Article)
Prosperity in Qatar and the consequent stresses on water resources resulted in a sustainable increase in the bottled drinking water market. Reports on health concerns and possible migration of chemicals from the plastic ...
Mechanistic insights into the remediation of bromide ions from desalinated water using roasted date pits
(
Elsevier B.V.
, 2017 , Article)
Bromide ions (Br−) are associated with toxic by-products that might be produced during the disinfection of drinking water. The removal of Br− from water using roasted date pits (RODPs) and activated carbon was investigated. ...
Visible light-driven metal-oxide photocatalytic CO2 conversion
(
John Wiley & Sons, Ltd.
, 2015 , Article)
In this work, nine photocatalysts were prepared by a conventional solid-state reaction method. The samples were characterized by X-ray diffraction, UV–Vis diffuse reflectance spectroscopy, surface area measurements based ...
Toxicity evaluation of selected ionic liquid compounds on embryonic development of Zebrafish.
(
Elsevier
, 2018 , Article)
Hydrate formation in seafloor pipelines is considered an economic and flow assurance issue for the oil and gas industries. Ionic liquids (ILs) have been recently used as potential hydrate inhibitors. Although branded as ...
Heavy metal removal from aqueous solution by advanced carbon nanotubes: Critical review of adsorption applications
(
Elsevier
, 2016 , Article Review)
The scarcity of water, especially in arid and semi-arid regions of the world is exerting great pressure on resources and establishing more need to provide good quality water for human and other consumptions. Water ...
Harvesting of intact microalgae in single and sequential conditioning steps by chemical and biological based – flocculants: Effect on harvesting efficiency, water recovery and algal cell morphology
(
Elsevier Ltd
, 2019 , Article)
Quick algae harvesting methodologies relating optimum flocculent dose (DOpt.), percentage harvesting efficiency (%HE) and percentage water recovery (%WRecovery) to the in-situ hydrodynamic properties of water-algae systems ...
Reducing flux decline and fouling of direct contact membrane distillation by utilizing thermal brine from MSF desalination plant
(
Elsevier B.V.
, 2016 , Article)
Fouling and scaling is one of the major challenges in membrane distillation process. This study investigates the utilizing of thermal rejected brine produced from multi-stage flash distillation (MSF) to minimize fouling ...
High-pressure CO2/N2 and CO2/CH4 separation using dense polysulfone-supported ionic liquid membranes
(
Elsevier B.V.
, 2016 , Article)
Four ionic liquids (ILs) were blended with polysulfone (PSF) to produce functional dense polymer-supported IL membranes (DPSILMs). The main aim was to investigate the applicability of the DPSILMs in industrial gas processing ...
