| Number | Title | Issue Date |
| 7357857 | Process for extracting bitumen Bitumen extraction done using a process comprising: (a) preparing a bitumen froth comprising particulate mineral solids and hydrocarbons dispersed in aqueous lamella in the form of an emulsion; (b) adding a sufficient amount of a paraffinic solvent to the froth to i... | 04/15/2008 |
| 5746907 | Method to remove metals from residuals A method is provided to remove metals from a residual oil containing an initial amount of a selected metal, the method comprising the steps of: providing a vessel for exposing the residual oil to a DC electric field having a strength of about one kV/inch or gr... | 05/05/1998 |
| 5219471 | Removal of metals and water-insoluble materials from desalter emulsions A process for measuring and treating oil-water stable emulsions derived from crude oil desalters is provided. Emulsion volume is measured, the emulsion is withdrawn, blended with aromatic-rich hydrocarbon, heated and three phases--water, oil and solids--a... | 06/15/1993 |
| 4904412 | Emulsion-forming composition An emulsion-forming composition for forming an emulsion for use in a process for selectively recovering germanium or arsenic from an aqueous solution thereof by liquid membrane technology is disclosed, said composition consisting essentially of: a solvent... | 02/27/1990 |
| 4634510 | Clarifying a contaminated fluid In the treatment of a contaminated liquid, an additive, such as finely divided adsorbent particles, is introduced into the liquid so that it combines physically, chemically or electrically with the contaminant to form a dispersion suspended in the liquid.... | 01/06/1987 |
| 4627901 | Separating wax from hydrocarbon mixture boiling in the lubricating oil range In order to separate wax from lubricating oil, it is necessary both to introduce free excess charge which is net positive or net negative into the wax-laden oil, preferably by charge injection, and to reduce the solubility for the wax (for example by cool... | 12/09/1986 |
| 4622119 | Method of promoting nucleation of solute in a solution To promote nucleation of a solute in a solution (e.g. wax dissolved in lubricating oil), free excess charge which is net unipolar is introduced into the solution, for example by charge injection, and the solubility for the solute is reduced (for example b... | 11/11/1986 |
| 4416754 | Compositions and process for dedusting solids-containing hydrocarbon oils Very finely divided particulate solids are removed from unconventional whole heavy petroleum crudes, heavy petroleum crude fractions, and residua, syncrudes and syncrude fractions, particularly shale oil and shale oil fractions, by the use of novel surfac... | 11/22/1983 |
| 4407706 | Process for dedusting solids-containing hydrocarbon oils Very finely divided particulate solids are removed from unconventional whole heavy petroleum crudes, heavy petroleum crude fractions, and residua, syncrudes and syncrude fractions, particularly shale oil and shale oil fractions, by the use of novel surfac... | 10/04/1983 |
| 4407707 | Process for dedusting solids-containing hydrocarbon oils Very finely divided particulate solids are removed from unconventional whole heavy petroleum crudes, heavy petroleum crude fractions, and residua, syncrudes and syncrude fractions, particularly shale oil and shale oil fractions, by the use of novel surfac... | 10/04/1983 |
| 4402807 | Process for dedusting solids-containing hydrocarbon oils A surface active agent characterized as an ethoxylated or propoxylated ester, or ester constituted of a 1,4 sorbitan skeleton to which at least one and up to three ethoxy, propoxy, or mixed ethoxy-propoxy substitutent, and at least one fatty acid substitu... | 09/06/1983 |
| 3951771 | Solids removal from viscous liquids What is disclosed is a method for treating a hydrophobic viscous feed, such as a syncrude fraction containing solids, to remove at least a portion of the solids having a minimum syncrude fraction therewith, characterized by a multi-step process. First, wa... | 04/20/1976 |
