Definitions

  • a common problem encountered in the production and transport of petroleum from a source of supply to a location where the petroleum is to be further processed or used is that the petroleum is often too viscous for transportation by conventional pipelines or other methods, such as tanker ships, barges, rail cars, and trucks.
  • the viscosity of crude petroleum oil or other heavy petroleum materials encountered in other contexts must be reduced so they can be pumped.
  • the addition to these materials of a highly miscible petroleum liquid, such as a light petroleum fraction, light weight hydrocarbons, kerosene, condensates, or diesel fuel, may reduce their viscosity but generally requires subsequent separation of the light petroleum fraction, usually by distillation.
  • Another method for reducing the viscosity involves the formation of an emulsion of petroleum and water.

  • energy are added to a mixture of water and immiscible petroleum.
  • the resulting emulsion has lower viscosity than the original petroleum material, and the emulsion is pumped to a collection point or a processing facility.

  • the emulsifier and aqueous phase may be recycled for reuse with further crude petroleum.
  • Oil exporting countries sometimes have foreign policies and political interests that are at odds with the interests of importing countries, and the continuing flow of funds to oil exporting countries from the importing countries has been viewed as counter to national and international security interests

  • Double bonds in the cross-linked molecule may be cis or trans double bonds, or may become single bonds in the blowing process.
  • the carbon-carbon and ether linkages formed as a result of the blowing process polymerize a portion of the monounsaturated fatty acids, such as oleic acid, and/or a portion of the polyunsaturated fatty acids, such as linoleic acid and linolenic acid, cross-linking the fatty acid-containing compositions.
  • the monounsaturated fatty acids such as oleic acid

  • the heat- bodying of fatty acid-containing compositions also forms cross linkages but tends to form more carbon-carbon linkages and fewer ether linkages.
  • the ester bonds can be broken to form cross-linked acids having two carboxylic acid groups.
  • hydrolysis of the ester bonds of a cross-linked triacylglycerol oil results in breaking the ester bonds holding each of the three fatty acids to the glycerol backbone of the triacylglycerol units, while cross-linkages between the fatty acids remain intact.
  • Hydrolysis can be carried out with heat and pressure, and under conditions which minimize the isomerization of remaining cis double bonds to trans double bonds, for example as described in US Patent No. 7,126,019 issued Oct. 24, 2006. Hydrolysis of the ester bonds of the cross-linked triacylglycerols yields a mixture of dicarboxylic acids and cross-linked dicarboxylic ethers. Selection of suitable starting fatty acid-containing compositions and cross-linking reaction designs will allow a portion of double bonds to remain in the cross-linked fatty acids ( Figure 2).
  • the dicarboxylic acids and dicarboxylic ethers are biobased and can be reacted to form ABA type surfactants, wherein the polar anhydrohexitol and ethoxylate chains are represented by A and the nonpolar cross-linked alkyl chain are represented by B. Because the melting points of branched-chain fatty acids are lower than the straight-chain counterparts, these branched B fatty acid chains of the surfactant molecules should crystallize at lower temperatures than the non-cross- linked counterparts. Thus, they may provide crude petroleum emulsion better viscosity reduction benefits at lower temperatures than more conventional polyol alkyl ethoxylates at low temperatures, better enabling low-temperature emulsion transport of petroleum.
