Solar hydrogen production via erbium oxide based thermochemical water splitting cycle
(
American Institute of Physics Inc.
, 2016 , Article)
The erbium oxide based water splitting (Eb-WS) cycle was thermodynamically studied by using the HSC Chemistry software and databases. The first step of the Eb-WS cycle involves thermal reduction of Er2 O3, whereas 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 ...
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 ...
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 ...
Investigation of the performance of biocompatible gas hydrate inhibitors via combined experimental and DFT methods
(
Academic Press
, 2017 , Article)
In this work, three ionic liquids (ILs) from the bio-compatible family of choline cations attached to anions of varying hydrophobicity namely: choline acetate (ChOAc), choline bistriflamide (ChNtf2), and choline chloride ...
Use of water in aiding olefin/paraffin (liquid + liquid) extraction via complexation with a silver bis(trifluoromethylsulfonyl)imide salt
(
Academic Press
, 2014 , Article)
This paper describes the extraction of C5-C8 linear -olefins from olefin/paraffin mixtures of the same carbon number via a reversible complexation with a silver salt (silver bis(trifluoromethylsulfonyl) imide, Ag[Tf2N]) ...
Influence of solution chemistry on Cr(VI) reduction and complexation onto date-pits/tea-waste biomaterials
(2013 , Article)
Tea waste (TW) and Date pits (DP) were investigated for their potential to remove toxic Cr(VI) ions from aqueous solution. Investigations showed that the majority of the bound Cr(VI) ions were reduced to Cr(III) after ...
Innovation and creativity in engineering design: The role of student engagement, team spirit and industry support
(
IEEE Computer Society
, 2014 , Conference Paper)
A case study on innovation and creativity in engineering design instruction has been presented. The novel approach emphases on the role of student engagement, team spirit and industry support to students. This paper presented ...
Industrial case studies in the petrochemical and gas industry in Qatar for the utilization of industrial waste heat for the production of fresh water by membrane desalination
(
Taylor and Francis Inc.
, 2013 , Article)
An investigation into the potential of using industrial low-grade waste heat in desalination using membrane distillation (MD) has been carried out. This investigation highlighted the need to work on fresh water production ...
