Emerging Brine Management Approaches for Sustainable Desalination in the GCC Countries
(
Qatar University Press
, 2023 , Conference Paper)
The major technologies employed in Gulf Cooperation Council (GCC) based commercial desalination facilities are classified into two categories: the membrane-based (mostly reverse osmosis (RO)) and thermal-based (primarily ...
Effect of Trace 100 vppm H2S on the Corrosion Behaviour of Plain Carbon and Microalloyed Steels in a Predominant Sweet Environment in High Flow Regime
(
Hamad bin Khalifa University Press (HBKU Press)
, 2018 , Conference Paper)
We investigate the effects of the presence of trace (100 vppm) H2S on the corrosion behaviour of plain carbon steel and its various micro-alloyed counterparts in a CO2 saturated (sweet) brine (0.5 M NaCl) environment, in ...
The Formation of Sulfide Scales on Carbon Steel in Saturated H2S
(
Hilaris
, 2020 , Conference Paper)
There are three contributing elements of corrosion of Carbon Steel in H2S environment: the effect of H2S on water chemistry; electrochemical reactions of the bare iron surface (both anodic and cathodic processes); and the ...
EFFECT OF COMPATIBILIZER ON MECHANICAL AND PHYSICAL PROPERTIES OF GREEN COMPOSITES BASED ON HIGH DENSITY POLYETHYLENE AND DATE PALM FIBER
(
DEStech Publications
, 2013 , Conference Paper)
Date palm leaves and wood are common wastes in the middle east. These natural fibers can be used as additives for polymers to develop new desired properties; they also have important economic and environmental advantages. ...
THE ENVIRONMENTAL EFFECT OF RECYCLE POLYPROPYLENE REINFORCED WITH WOOD AND GLASS FIBERS BY USING LIFE CYCLE ASSESSMENT
(
Politecnico di Torino - Department of Mechanical and Aerospace Engineering Italy
, 2012 , Conference Paper)
In this paper investigates the environment impact for recycle polypropylene which reinforced
with natural wood fiber by extrusion. The purpose of this work was to reduce the
environmental impact for the new products by ...
Effect of Alkaline Activators on the Mechanical Properties of Geopolymer Mortar
(
Qatar Univesrity Press
, 2020 , Conference Paper)
"Geopolymerization is a process where silica and alumina rich source materials turn
into excellent binding materials by the aid of alkali solutions. Materials such as fly ash
are by-products in energy power plants. Fly ...
Evaluation of Bond Strength Between Carbon Fiber Reinforced Polymer (CFRP) Composites with Modified Epoxy Resins and Concrete
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Rehabilitation and strengthening of concrete structures are becoming more significant
in civil engineering applications. The use of externally bonded Fiber Reinforced
Polymers (FRP) is one of the methods to strengthen and ...
Dosage Optimization of Polypropylene Fiber for Strength Enhancement of Cementitious Composites
(
Qatar Univesrity Press
, 2020 , Conference Paper)
"Concrete is the most commonly used materials for construction in Qatar as well as in
the world. Exposure to sever environmental conditions causes physical deterioration
of concrete structures and significantly affect ...
High and Ultra-high Performance Concretes: A Solution to Reinforced Concrete Durability under Harsh Climate of Arabian Gulf
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Reinforced concrete (RC) infrastructure in the Arabian Gulf region deteriorates under
severe environmental conditions after only short service life. To overcome this problem,
it is imperative to employ high-quality concretes ...
