  • Patent number: 9963642
    Abstract: It has been discovered that metals and/or amines can be removed or transferred from a hydrocarbon phase to a water phase in an emulsion breaking process by using a composition that contains water-soluble hydroxyacids. Suitable water-soluble hydroxyacids include, but are not necessarily limited to glycolic acid, gluconic acid, C2-C4 alpha-hydroxy acids, poly-hydroxy carboxylic acids, thioglycolic acid, chloroacetic acid, polymeric forms of the above hydroxyacids, poly-glycolic esters, glycolate ethers, and ammonium salt and alkali metal salts of these hydroxyacids, and mixtures thereof. The composition may also include at least one mineral acid to reduce the pH of the desalter wash water. A solvent may be optionally included in the composition. The invention permits transfer of metals and/or amines into the aqueous phase with little or no hydrocarbon phase undercarry into the aqueous phase.

  • Patent number: 9845434
    Abstract: Biological source oils, including, but not limited to, algae oil, stabilize the presence of asphaltenes in petroleum feedstocks, such as crude oil, to help avoid or prevent fouling and/or corrosion in the production, transferring and processing of the petroleum feedstocks. Chemical additives such as phenol-based resins, and reaction products or combinations of long chain alpha-olefins and/or small chain aldehydes and/or long chain alkyl phenate sulfides and/or metal oxide-based colloidal hydrocarbon-based nanodispersions, may also stabilize the presence of asphaltenes in petroleum feedstocks. By “stabilizing” is meant keeping the asphaltenes in solution in the petroleum feedstocks.

  • Patent number: 8765020
    Abstract: Mitigating or preventing corrosion of metal may be achieved in systems that are alkaline, such as carbon dioxide capture systems. The method may include adding an additive to a system wherein the system is at an alkaline pH; the system has both O2 and CO2 present; or the system is at an alkaline pH and has both O2 and CO2 present. The additive may be selected from the group consisting of: quaternary aromatic amines; quaternary alkyl substituted aromatic amines; and combinations thereof. The corrosion inhibiting properties of the additives may be increased by use of synergistic combinants. The abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
