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 ... -
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 ... -
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 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. ... -
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 ... -
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 ... -
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 ... -
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, ... -
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 ... -
A novel algorithm for molecular synthesis using enhanced property operators
( Elsevier Ltd , 2008 , Article)Traditionally process design and molecular design have been treated as two separate problems, with little or no feedback between the two approaches. Introduction of the property integration framework has allowed for ... -
Dynamic risk assessment using failure assessment and Bayesian theory
( Elsevier Ltd , 2009 , Article)To ensure the safety of a process system, engineers use different methods to identify the potential hazards that may cause severe consequences. One of the most popular methods used is quantitative risk assessment (QRA) ... -
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), ...
