Characterization of hollow fiber properties during the melt spinning process.
(2000)
Substitution of hollow fibers for solid fibers would not only preserve the web properties (opacity and compression), but would actually improve the strength of each fiber. Hence, hollow fibers could be substituted for solid ...
Optimal design of crude oil distillation plants.
(2001)
Crude distillation is the first processing unit in the refinery. It separates the crude in to distillates, which are either intermediate products further processed or raw materials for the chemical industry. Crude distillation ...
Application of electrochemical technique to measure mass transfer of macromolecules in a flow system.
(1980)
Steady state voltammetry and the scanning methods were used to obtain voltammograms (current-potential curves) with well defined mass transfer regions.
An investigation into the properties and behaviors of alkyldiphenyl oxide disulfonate surfactants.
(2001)
An overview of surfactant adsorption included a discussion of the importance of surfactant adsorption in petroleum applications, a summary of the history of surfactant adsorption research and the mechanisms that have been ...
Carbon dioxide extraction of ethanol from water at elevated pressures /
(1982)
Experimental results from the continuously fed apparatus demonstrate that a 23.4% conversion of a 49.5 mole% ETOH-H(, 2)O feed stream to an 88 mole% ETOH-H(, 2)O overhead stream may be accomplished with liquid carbon dioxide ...
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.
