Treatment of waters colored with methylene blue dye by vacuum membrane distillation
( Elsevier B.V. , 2004 , Article)Textile industries consume large amounts of water and generate highly dye-contaminated effluents. Textile wastewaters have to be treated in order to be recycled in the process or to meet legislative requirements before ... -
Neural network model-based predictive control of liquid–liquid extraction contactors
( Elsevier Ltd , 2004 , Article)The inherent complex nonlinear dynamic characteristics and time varying transients of the liquid–liquid extraction process draw the attention to the application of nonlinear control techniques. In this work, neural ... -
Modeling, simulation and control of a scheibel liquid–liquid contactor: Part 1. Dynamic analysis and system identification
( Elsevier B.V. , 2004 , Article)The liquid–liquid extraction process is well-known for its complexity and often entails intensive modeling and computational efforts to simulate its dynamic behaviour. However, rigorous mathematical models are usually ... -
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 ... -
A simplified method for calculating saturated liquid densities
( Elsevier B.V. , 2004 , Article)A simplification for the Nasrifar–Moshfeghian (NM) liquid density correlation has been developed. A replacement for the Mathias and Copeman temperature-dependent term with the original Soave–Redlich–Kwong equation of state ... -
Simulation of large capacity MSF brine circulation plants
( Elsevier B.V. , 2006 , Article)New multistage flashing desalination units (MSF) are being constructed with large capacity that may vary from 50,000 to 75,000 m3/d. This is almost 2–3 times the conventional unit capacity of 27,000–32,000 m3/d, which were ... -
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 ... -
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 ... -
A Property Based Approach for Simultaneous Process and Molecular Design
( Elsevier B.V. , 2009 , Article)In this work, property clustering techniques and group contribution methods are combined to enable simultaneous consideration of process performance requirements and molecular property constraints. Using this methodology, ... -
Bench-scale and packed bed sorption of methylene blue using treated olive pomace and charcoal
( Elsevier Ltd , 2006 , Article)A combination of olive pomace after solvent extraction and charcoal produced from the solid waste of olive oil press industry was used as an adsorbent for the removal of methylene blue (MB) dye from aqueous solutions. Batch ... -
Influence of adhesive thickness and filler content on the mechanical performance of aluminum single-lap joints bonded with aluminum powder filled epoxy adhesive
( Elsevier B.V. , 2007 , Article)The objective of this study was to develop information on the influence of adhesive thickness and aluminum filler content on the mechanical performance of aluminum joints bonded by aluminum powder filled epoxy. The adhesive ... -
A systematic visual approach to molecular design via property clusters and group contribution methods
( Elsevier Ltd , 2008 , Article)In this work, a new simple yet effective, systematic method to synthesize and design molecules is presented. Visualization of the problem is achieved by employing an annex to the recently developed property clustering ... -
Handling data uncertainties in event tree analysis
( Elsevier B.V. , 2009 , Article)Event tree analysis (ETA) is an established risk analysis technique to assess likelihood (in a probabilistic context) of an accident. The objective data available to estimate the likelihood is often missing (or sparse), ... -
