Unconventional crude oil extraction, transportation, and downstream refining have encountered a huge formation of petroleum emulsion (or rag layer), which causes serious problems such as equipment corrosion, loss of crude oil, and catalyst poisoning.…
The use of NiO nanoparticles as asphaltene co-precipitant additives is studied to improve the upgraded oil's properties and potentially reduce the solvent-to-oil ratio for the in-situ upgrading of heavy oils via solvent deasphalting. Asphaltene…

This paper explains and analyses the process where two series of acrylic random bipolymers, based on alkyl acrylate/carboxyalkyl acrylate (KC) and alkyl acrylate/acrylic acid (KA), were prepared by means of emulsion polymerization technique. In both,…
A novel kind of random acrylic terpolymers based on butyl acrylate (B), 2-(dimethylamino)ethyl acrylate (Ae), and 2-carboxyethyl acrylate (Ce) monomers was obtained by emulsion polymerization. Monomers’ weight ratios were varied, keeping in all cases…
After selective solvent extraction, the volatile and non-volatile vanadium and nickel distributions for two Venezuelan heavy crude oils and the NIST Standard Reference Material SRM 8505 were determined for the Entrained n-pentane (C5) maltenes,…
