T. Kevin Swift
The American Chemistry Council (ACC) has launched a new set of indexes covering nearly 30 segments of the U.S. specialty chemicals market. (The first, which dealt with plastic additives, was discussed in the July issue, p. 13.) This is the first set...

Combustion of Mixtures: A Modified IFC Approach

Apr 2, 2012
Gary Mueller
While most studies on flares have been done with single hydrocarbon fuels or binary mixtures, the reality of most industrial flares is that they see different mixtures of many gases. Over the past 5 years the International Flare Consortium (IFC) has been conducting research on just this issue. In a...

Tutorial: The Chemistry of Refinery Fouling

Apr 2, 2012
Irv Wiehe
The chemistry of refinery fouling is well enough understood to mitigate nearly all fouling. The key information required are the location of the foulant, elemental analysis of the foulant, and identification of precursors in the oil flowing through the fouled unit. Most organic fouling is caused by...

Asphaltene Instability Measured by Small-Angle Neutron Scattering

Oct 19, 2011
Michael P. Hoepfner
Asphaltenes are defined as the petroleum fraction that precipitates with the addition of a normal alkane; however, it was only recently discovered that there is a strong time-dependency for precipitation in oil/n-alkane mixtures [1]. It was found that at low precipitant concentrations, asphaltenes...

Rapid Deposition of Titania Nanoparticles for Dye Solar Cells

Oct 18, 2011
Rocco Panella
Dye-sensitized solar cells (DSSCs), while only having been designed about twenty years ago, are considered to be one of the most promising third-generation solar cell technologies among experts. One of the key features of DSSCs is a mesoporous, 10 micron layer of titania nanoparticles which acts as...
