Cloud point extraction (CPE) is an alternative suitable separation technique, which is based on the phenomenon of turbidity of the solution where the surfactants monomers aggregate and scattering visible light (PALEOLOGOS et al., 2005).
PDVSA in the autumn of 2005 also lost a major premium on ULSD spot prices offered on the US Gulf Coast, while the Venezuelan diesel did not meet the EU's cold property requirements on cloud point and cold filter plugging point (see background in down19VenzRefNov7-05).
We brought about new favorable properties in this material," Abdous said to INIC.Application of new nanocomposites for synthesizing industrial paints and its expansion to construction paints as well as examination of their properties and applications are much helpful, he said, and added, "The results of this research could be effective in pollution control and saving oil resources considering environmental merits and economical points."To conduct the project, Abdous said he had used an active nonionic surface and substance at temperatures above the cloud point to synthesize a nanocomposite.
