Liquid crude hydrocarbon composition

摘要

Disclosed is a liquid crude hydrocarbon composition containing (a) a liquid crude hydrocarbon having an API gravity of less than or equal to about 20; and (b) a minor amount of a blend comprising (i) one or more hydrocarbon-containing solvents having an aromatic content of at least about 10 wt. %; and (ii) one or more asphaltene modifiers selected from the group consisting of an aromatic sulfonic acid or salt thereof, an aliphatic sulfonic acid or salt thereof and an alkyl-substituted hydroxyaromatic carboxylic acid or salt thereof. Also disclosed is a method for transporting a liquid crude hydrocarbon having an API gravity of less than or equal to about 20.

1. A liquid crude hydrocarbon composition comprising:
(a) a liquid crude hydrocarbon having an API gravity of less than or equal to about 20; and (b) a minor amount of a blend comprising (i) one or more hydrocarbon-containing solvents having an aromatic content of at least about 20 wt. %; and (ii) one or more asphaltene modifiers which are one or more branched C8 to C60 olefin sulfonic acids or salts thereof prepared by sulfonating an isomerized C8 to C60 olefin; wherein the one or more asphaltene modifiers are present in an amount ranging from about 50 ppm to 400 ppm, based on the total weight of the blend.
