The properties of asphaltenes derived from Venezuelan vacuum residues have been investigated using several techniques. X-ray diffraction and Differential Scanning Calorimetry (DSC) and infrared spectrometry results indicate that asphaltenes are complex mixtures that form nanostructures with some (low) degree of ordering, probably consistent with a sheet-like arrangement of aromatic nuclei. Nanostructures seem to be also present in solutions of the asphaltenes in toluene, and an increase in their concentration ...

Hydrophilic surfactant molecules with the proper formulation are able to break W/O emulsions stabilized by asphaltenes and other lipophilic amphiphiles as found in the effluent of petroleum wells. The demulsifier performance is here tested according to two critera. The first one, as in previous research, is the minimum dose of demulsifier used to attain the minimum stability at the so-called optimum formulation in a simplified bottle test. The second criterion is the value of this minimum stability ...

The performance of several extended surfactants as water-in-crude oil emulsion breakers was evaluated using two criteria: (1) the demulsifier dose required (CD*) to attain the minimum stability at the so-called optimum formulation, and (2) the corresponding low minimum stability value. These surfactants were found to behave in the same way as typical commercial demulsifiers do; i.e., they require a lower dose CD* when their hydrophilicity is slightly greater. The reported data for a dozen different ...

The UK's National Health Service (NHS) generates uniquely rich data that should be rapidly deployed for policy and service improvement, yet researchers report difficulties in accessing these data.

The asphaltenes and the fractions A1 and A2, as well as mixtures of the two fractions were tested in a Langmuir–Bodgett trough. It was found that the asphaltenes and the fraction A2 had similar behavior and higher compressibility than the fraction A1. This is because the molecules of A2 are more flexible than the molecules of A1 as they have aliphatic chains ...
