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 ...
The synthesis and characterization of chlorinated polyethylene-g-styrene and its application as a blend modifier.
(1980)
The graft products were purified by solvent extraction followed by selective precipitation to remove the styrene homopolymer and unreacted chlorinated polyethylene. Solubility behavior of CPE and polystyrene in various ...
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 ...
A global optimization framework for stochastic integrated refinery planning with nonlinear unit models under demand and price uncertainties
(2020-09-11)
The refining industry is facing increased volatility in the global market such as lower economic margins. In this situation, refinery production planning becomes a substantial tool to utilize all potentials to extend the ...
Molecular theoretical equation of state for applications to selected pure liquids and dense fluids of natural gas, petroleum hydrocarbons and coal chemicals /
(The University of Oklahoma., 1984)
A new equation of state applicable to both polar and nonpolar compounds has been developed. It is modeled after the nonspherical square-well potential. The repulsive pressure is approximated by contributions from the ...
Propylene metathesis with rhenium oxide supported by -alumina as catalyst, including kinetic and initial reaction studies.
(1980)
There are seven catalysts studied, i.e., NH(, 4)ReO(, 4)/(gamma)Al(, 2)O(, 3), NH(, 4)ReO(, 4)/TiO(, 2), NaReO(, 4)/(gamma)Al(, 2)O(, 3), NH(, 4)ReO(, 4)/3A(K) zeolite, NH(, 4)ReO(, 4)/3A(Ca) zeolite, NH(, 4)ReO(, 4)/13X(Na) ...
Computational Investigation of the Behavior of Nanoparticles and Surfactants at the Oil-Water Interface
(2021-12)
Surfactants and nanoparticles (NPs) are commonly used to stabilize emulsions, which have found applications in different areas. The fundamental understanding of the behavior of surfactants and NPs adsorbed at the oil-water ...
Applications of multiproperty analysis in the prediction of complex-system thermophysical behavior.
(1981)
Thermophysical-property data for over fifty organic compounds, including high-boiling-temperature hydrocarbons typical of coal-derived fluids, have been used to establish the feasibility of the technique. The overall average ...
Analysis of melt blowing dies using computational fluid dynamics .
(2007)
For a single annular jet and the blunt slot die, a previously developed rheological model was used to predict the fiber diameter, velocity, and temperature. Then, these were used to set boundary conditions in simulations ...
