Concentration of sucrose solutions via vacuum membrane distillation
(
Elsevier B.V.
, 2005 , Article)
The potential use of vacuum membrane distillation (VMD) process for the concentration of sucrose solution was examined. The effect of several parameters, including feed temperature, flow rate, and initial sucrose concentration ...
Viscous-Gravity spreading of oil on water
(
John Wiley & Sons, Inc.
, 2001 , Article)
Spreading of oil on calm water is analyzed for the second stage of spread, which is controlled by a balance between gravity and viscous forces. The analysis, using the integral boundary-layer method, agreed well with a ...
Photodegradation of methylene blue dye by the UV/H2O2 and UV/acetone oxidation processes
(
Elsevier B.V.
, 2005 , Article)
The photodegradation of methylene blue (MB) dye in aqueous solutions was investigated using a laboratory-scale UV lamp in the presence of hydrogen peroxide (H2O2). Different initial concentrations of dyes (10, 20, 30, 40 ...
Representation of Adsorption Data for the Isopropanol-Water System using Neural Network Techniques
(
WILEY-VCH Verlag
, 2005 , Article)
Molecular sieves and palm stone, a newly developed bio-based adsorbent, were used to break an azeotropic isopropanol-water system via an adsorptive distillation process. Equilibrium data at different inlet water contents ...
Operational modeling of multistream heat exchangers with phase changes
(
Wiley Subscription Services, Inc., A Wiley Company
, 2009 , Article)
Multistream heat exchangers (MSHE) enable the simultaneous exchange of heat among multiple streams, and are preferred in cryogenic processes such as air separation and LNG. Most MSHEs are complex; proprietary and involve ...
Adaptive and Predictive Control of Liquid-Liquid Extractors Using Neural-Based Instantaneous Linearization Technique
(
WILEY-VCH Verlag GmbH & Co.
, 2006 , Article)
Nonlinearity of the extraction process is addressed via the application of instantaneous linearization to control the extract and raffinate concentrations. Two feed-forward neural networks with delayed inputs and outputs ...
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 ...
