(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Nowadays, global fresh water shortage is becoming the most serious problem affecting the economic and social development. Water treatment including seawater desalination and wastewater treatment is the main technology for ...
Electrochemical reduction of CO2 into formate/formic acid: A review of cell design and operation
(
Elsevier
, 2023 , Article Review)
The release of carbon dioxide (CO2) into the atmosphere is threatening the environment and ecosystems, resulting in major challenges to sustainable development for modern industry. In this context, CO2 electrochemical ...
Early gas kick detection in vertical wells via transient multiphase flow modelling: A review
(
Elsevier B.V.
, 2020 , Article Review)
Gas influx from reservoir into the wellbore during drilling, tripping, or other operations, is a hazard. In the early stages, the influx may be nearly undetectable, but the kick can rapidly change from a seemingly steady ...
Computational fluid dynamics simulation of an Inert Particles Spouted Bed Reactor (IPSBR) system
(
De Gruyter Open Ltd
, 2020 , Article)
A novel system for contacting gases and liquids, suitable for many applications involving gas-liquid contact such as CO2 capture and brine desalination, has been simulated and experimentally validated. The system comprises ...
