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 ...
Protecting environment and assuring efficient energy transfer using ionic liquids
(
Hamad bin Khalifa University Press (HBKU Press)
, 2018 , Conference Paper)
Gas hydrates are ice-like crystalline compounds that are formed when small gas molecules get trapped within the water molecules under high pressure and low-temperature conditions in oil and gas transmission lines. The ...
Development of Green Inhibitors to Prevent Hydrates Formation, Protect Environment and Reduce Energy Cost in Oil and Gas Industry
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Gas hydrates are identified as ice-liked solid, crystalline compounds having polyhedral water cavities, where gas molecules get trapped during operation under high pressure and low temperature condition. These hydrates ...
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. ...
Ionic Liquids as Multi-purpose Inhibitors to avoid Natural Gas Hydrates during Gas Processing
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
The issue of hydrate formation during gas processing is a challenging problem for the oil and gas industries. Billions of dollars spent annually to get rid of the blockage of pipelines due to hydrate clogging by applying ...
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 ...
Structural and magnetic properties of Ni1-xZnxFe 2O4 (x=0, 0.5 and 1) nanopowders prepared by sol-gel method
(2013 , Article)
A series of nanostructured Ni-Zn ferrites Ni1-xZn xFe2O4 (x=0, 0.5 and 1) with a grain size from 24 to 65 nm have been prepared with a sol-gel method. The effect of composition and sintering temperature on morphology, ...
Influence of composite particle formation on the performance and economics of grit removal
(
Elsevier Ltd
, 2017 , Article)
Grit is routinely removed at the headworks of municipal wastewater treatment works to limit its onerous impact on downstream processes. Grit separation technologies are normally based on sedimentation of a homogeneous ...
