A new molecular weight/polarity map based on the Schard-Hildebrand solubility equation has been developed for petroleum residua. A series of extractions are performed with solvents of increasing solubility parameter, and the fractions are analyzed by vapor pressure osmometry for nuer average molecular weight and by analytical-scale size exclusion chromatography for molecular weight spread.

OIL INDUSTRY CONVERSIONS Crude petroleum
LEARN ABOUT OIL INDUSTRY CONVERSIONS Crude petroleum, and the refined products made from crude oil, are normally measured either by volume in gallons and US barrels, or by weight in tons or tonnes. The relationship between volume and weight is usually measured by density in the United Kingdom (the alternative measure is relative density or specific gravity).
WO2013142356A1 - Method for reducing silicone …
The current invention provides an improved petroleum coking process wherein the risk of silicone poisoning of units downstream of the coke drums is reduced. The method of the current invention controls the foam layer within the coke drum by injection of a silicone anti-foam agent in a highly aromatic carrier fluid such as slurry oil.

Petroleum - Infogalactic: the planetary knowledge core
Petroleum, in one form or another, has been used since ancient times, and is now important across society, including in economy, politics and technology. The rise in importance was due to the invention of the internal coustion engine, the rise in commercial aviation, and the importance of petroleum to industrial organic chemistry, particularly the synthesis of plastics, fertilizers, solvents

The alytic upgrading of heavy crude oil in-situ: the role …
2012/5/1· The objective of this process is to breakdown high molecular weight hydrocarbons in the heavy oil into lighter and more valuable crude oil (Sanchez, et al., 2005). It has been reported that the addition of hydrogen donor to the alytic cracking of heavy oil promotes asphaltenes breakdown to yield aliphatic oil and reduce coke formation in the process (Curtis and Cassell, 1988).
