- n. A name originally given by Boussingault to a residue left on distilling asphalt from an oil-bath.
Sorry, no etymologies found.
Asphalts normally contain between 5 and 25% by weight of asphaltenes and may be regarded as colloids of asphaltene micelles dispersed in maltenes.
The volumes set out above refer to potentially recoverable volumes of asphaltene reduced bitumen resources and were calculated at the outlet of the proposed extraction plant.
Atmospheric Administration, said the oil has an unusually high amount of asphaltene -- heavy ingredients that make it more suitable for paving roads than powering cars.
The aggregation of the asphaltene (a.k.a. diesel sludge) which leads to the lowering of viscosity lasts for several hours, according to the abstract I linked above, which is plenty of time for the fuel to make it from this device attached to the common rail out to the injector.
The method does not change the temperature of the crude oil; instead, it temporary aggregates paraffin particles or asphaltene particles inside the crude oil into large ones.
(compounds of nitrogen and sulphur) and asphaltene or tar.
"If we look at it from a refiner´s perspective, you´re increasing the saturates content, slightly reducing the aromatics, but significantly reducing the asphaltene content and the resin content.
