Optimal design of water utilization systems in refineries and process plants.
(1999)
The intensive use of water in refineries and process plants was the object of several studies starting in the early eighties. All these Studies have aimed at the reduction of the water consumption as well as the allocation ...
Use of micellar-enhanced ultrafiltration and ligand-modified micellar-enhanced ultrafiltration processes to remove dissolved metals and organic solutes from aqueous streams.
(1997)
The effectiveness of micellar-enhanced ultrafiltration (MEUF) and ligand-modified micellar-enhanced ultrafiltration (LM-MEUF) techniques for removal of heavy metal ions and/or organic pollutants from aqueous streams are ...
Technical and economic feasibility study of polyelectrolyte-enhanced ultrafiltration (PEUF) for the removal of multivalent ions from water.
(1998)
The results of this work were modeled using an ion-binding model based on a two-phase approximation theory to predict rejection of the hardness ions. The model is highly accurate in prediction of rejections at low ...
Electrically conducting polymer matrix composites: A morphological and structural perspective.
(1998)
Wide angle x-ray scattering (WAXS), conductivity, optical microscopy, stress relaxation, and differential scanning calorimetry (DSC) measurements, were used to show the effect of filler addition and uniaxial orientation ...
On-Line measurement and mathematical modeling of fiber properties during the melt spinning and melt blowing processes /
(1997)
The on-line measurements during the melt spinning process were used to quantitatively evaluate the effect of molecular orientation (caused due to threadline stress) on the crystallization rate of polymers.
The thermodynamics and kinetics of precipitation of anionic surfactants and surfactant mixtures.
(1997)
An important characteristic of ionic surfactants is their tendency to precipitate from aqueous solution. Both the thermodynamics and kinetics of surfactant precipitation are important when determining formulation compositions ...
The generalized asymmetric rule (GAR): The optimization of mixture asymmetry in a noncubic equation of state.
(1998)
This work uses a preexisting, noncubic EOS to predict polar/nonpolar pure components. This EOS uses the mixing rules of a preexisting local composition model (LCM) that can simultaneously (1) simulate both liquid and vapor ...
Catalytic cracking of poly(ethylene) and poly(styrene) by silica-alumina, HZSM-5 zeolite and sulfated zirconia.
(1997)
The catalytic cracking mechanisms of poly(ethylene) and poly(styrene) differ considerably from their thermal cracking mechanisms. In the case of poly(ethylene), thermal cracking leads to the formation of a wide range of ...
Surfactant behavior in the mechanisms of ink removal from secondary fiber in flotation deinking.
(1997)
To date, the majority of the research into ink removal from secondary fiber by the flotation deinking method has centered about empirical research, and the fundamental mechanisms have not been well understood. In this ...
Novel catalytic materials for carbon dioxide reforming of methane under severely deactivating conditions.
(1999)
Promotion of the ZrO2 support with cerium and lanthanum resulted in increased activity and stability of the catalyst. The improved performance of the promoted catalyst can be attributed stabilizing the surface area for ...
