Modeling

A mathematical model has been developed to simulate the performance of an integrated extraction-stripping process based on the use of hollow fiber contactors. The model allows one to predict the time-dependent concentration profiles of the two phases involved in an individual extraction or stripping

This paper presents a study of enzymatic esterification of oleic-acid and i-amyl alcohol. The product of this reaction, i-amyl-oleate, is widely used as a bio-lubricant. During the esterification reaction, water is produced as a by-product, which has a disadvantageous effect on the reaction rate and

This paper presents the results of an optimization study, based on minimum water cost, to explore the feasibility of the hybridization of RO and MSF processes. The study explores the possible improvement of MSF process economics. Nine different scenarios for the production of the same capacity of de

Mechanism specificity of ion separations in drinking water is necessary for the study of modeling transfer of calcium salt through nanofiltration membrane. In the present work, we have investigated a mathematical model which can specify the transfer phenomena of solute through a nanofiltration membr

The objective of this work is to design a low-cost evaporator. The new type of evaporator suggested here is of the spray-type, i.e., spaying the seawater into fine droplets to evaporate the water. The cost of this type of evaporator is comparatively low because no heat exchangers are required. The e

The separation performance of Na+ ions from NaCl solution has been investigated by electrodialysis at constant voltage mode of operation. TS-1-10 electrodialysis equipment (Tokuyama) modified with rotameters was employed in experimental studies. During an unsteady-state run of the ED system, both in

Seawater desalination by parallel feed multiple-effect evaporation has a simple layout in comparison with other multiple-effect or multistage desalination systems. Several operating configurations are analyzed, including the parallel flow (MEE–P), the parallel/cross flow (MEE–PC), and systems combin
