Modeling, simulation and control of a scheibel liquid–liquid contactor: Part 2. Model-based control synthesis and design
(
Elsevier B.V.
, 2004 , Article)
This study describes an application of model-based control techniques to a liquid–liquid extraction process. The control design is based on a reduced order model of the process obtained by system identification. A multi-loop ...
Integrating hybrid systems with existing thermal desalinationplants
(
Elsevier B.V.
, 2004 , Article)
In Gulf countries, most power plants are co-generation power desalting plants (CPDP) that generate electric energy and also produce fresh water through the desalination of seawater. This paper provides detailed technical ...
Aquifer storage and recovery (ASR): A strategic cost-effective facility to balance water production and demand for Sharjah
(
Elsevier B.V.
, 2004 , Article)
Aquifer storage and recovery was evaluated as a strategic water storage facility and as a tool to reduce overallcost of water production. This work investigated the size, cost, and mode of operation required to run the ...
Desalination using ambient air: simulation and energy optimization
(
Elsevier B.V.
, 2004 , Article)
This work applies to process design, simulation, analysis, and optimization to minimize the energy requirements for producing desalinated water using ambient air (humidification and dehumidification process). The only ...
Simulation and economic evaluation of natural gas hydrates [NGH] as an alternative to liquefied natural gas [LNG]
(
Elsevier B.V.
, 2005 , Article)
Despite the fact that relatively little is known about the ultimate resource potential of natural gas hydrates, it is certain that gas hydrates are a vast storehouse of natural gas and significant technical challenges need ...
Investigation of the use of TiO2 doped with metal ions in water disinfection
(
IWA Publishing
, 2010 , Article)
This research was conducted to improve titanium dioxide by transition metal doping using cooper. Sol gel method was used to prepare metal doped TiO 2. Titanium isopropoxide and commercial TiO2 P25 were employed as catalyst ...
Modeling of mass transport of aqueous solutions of multi-solute organics through reverse osmosis membranes in case of solute–membrane affinity: Part 1. Model development and simulation
(
Elsevier B.V.
, 2005 , Article)
A two-dimensional mathematical model is developed for transport of multi-solute liquid (aqueous) solutions through reverse osmosis membranes in which strong affinity may exist between the membrane polymer and the solutes. ...
A predictive model for the assessment of the temperature polarization effect in direct contact membrane distillation desalination of high salinity feed
(
Elsevier B.V.
, 2014 , Article)
Temperature polarization is one of the major sources responsible for flux drop in membrane distillation systems due to the reduction in the driving force across the membrane. The present study offers a predictive model ...
Room-temperature development of thin film composite reverse osmosis membranes from cellulose acetate with antibacterial properties
(
Elsevier B.V.
, 2014 , Article)
A cellulose acetate thin film composite (CA TFC) membrane was developed by direct casting of CA onto an ultrafiltration membrane support. The flux through the CA TFC membrane was, as expected, inversely proportional to the ...
Effect of operational parameters on distillate flux in direct contact membrane distillation (DCMD): Comparison between experimental and model predicted performance
(
Elsevier B.V.
, 2014 , Article)
Membrane distillation (MD) is a thermally driven process where hydrophobic membranes are used to separate saline hot feed solution and cold stream of water and allow water to evaporate due to temperature difference. This ...
