    摘要: The present invention provides a process for the removal of contaminants from contaminated crude oil in a vessel. An organic solvent stream is provided to the vessel containing crude oil. After mixing, an organic solvent bottom phase is allowed to form. The bottom phase comprises at least a portion of the organic solvent stream and at least a portion of the contaminants. The bottom phase is removed from the vessel, while the remaining crude oil is retained in the vessel. An aqueous stream is provided to the vessel and mixed with the remaining crude oil, allowing an aqueous bottom phase to form. The aqueous bottom phase is removed from the vessel, while the remaining crude oil is retained in the vessel.

    摘要: A method for removing sulfolane from hydrocarbon streams by serial separation using raffinate wash column and at least one raffinate wash drum. The separation may be particularly useful in retrofitting existing separation facilities to produce motor fuels meeting the specifications requiring lower sulfolane content. A method is provided for the purification of a hydrocarbon-containing stream having a sulfolane therein. The method includes separating a first sulfolane-depleted stream from a hydrocarbon stream in a first counter-current separation unit and then separating a second sulfolane-depleted stream from the first sulfolane-depleted stream in a second counter-current separation unit. The first and second counter-current separation units are preferably different and chosen from a raffinate wash column or at least one raffinate wash drum. An apparatus for performing the methods is also described.

    摘要: Methods are provided for extracting heterocyclic compounds, organometallic compounds, and polynuclear aromatic hydrocarbons from a hydrocarbon feedstock such as crude oil or a crude fraction. The heterocyclic compounds and organometallic compounds are removed from the hydrocarbon feedstock through one or more successive extractions to form a first raffinate. The extractions use a first solvent system containing an ionic liquid formed from carbon dioxide and water. The polynuclear aromatic hydrocarbons are removed from the first raffinate using a second solvent system containing an aprotic solvent such as NMP, DMSO, aromatics, or combinations thereof. The extracted compounds remain chemically intact and may be fractionated for further applications. Further methods are provided for producing a hydrocarbon raffinate having reduced levels of heterocyclic compounds, organometallic compounds, and 2-4 cycle polynuclear aromatic hydrocarbons.

    摘要: Methods are provided for upgrading the quality of an asphalt containing wax. This can include base asphalts that naturally contain elevated levels of wax, such as base asphalts with a wax content of at least 3.0 wt %. Additionally or alternately, this can include a base asphalt containing subsequently added wax. Wax generated at a refinery can be added to an asphalt along with a pour point depressant to form an asphalt product. The additional wax can reduce the viscosity of the asphalt product at higher temperatures so that the asphalt product can be mixed and stored at a tower temperature. Additionally, the pour point depressant can unexpectedly improve the low temperature properties of the wax-containing asphalt product.

    摘要: Non-carcinogenic bright stock extracts and/or deasphalted oils are produced from reduced hydrocarbon feedstocks. Such non-carcinogenic products are produced by establishing a functional relationship between mutagenicity index and a physical property correlative of hydrocarbon type for the bright stock extract or deasphalted oil and determining a critical physical property level which, when achieved, results in a product having a mutagenicity index of less than about 1.0. Process conditions are established so that a product stream achieving the desired physical property level can be produced. Non-carcinogenic bright stock extracts and/or deasphalted oils are then processed utilizing the conditions so established. A bright stock extract and a deasphalted oil substantially free from mutagenic activity, as well as processes for their production are also provided herein.

    摘要: Process for re-refining used lubrication oil by contacting the used lube oil in a first extraction zone with a light hydrocarbon solvent, for example, propane, yielding a first extract and raffinate. The solvent is removed from the first extract to recover desired lubrication stock base. The first raffinate is then solvent-extracted, using the same solvent to produce a second extract and raffinate. The solvent is then removed from this second extract to yield an oil which can be further refined for separation of valuable constituents or burned as fuel oil. The second raffinate is flashed to remove any remaining solvent and leave an easily discardable solid residue.
