Process for enhancing the value of hydrocarbonaceous natural resources
InactiveUS20050167337A1Little and wasteLittle and valueHydrocarbon distillationTreatment with hydrotreatment processesSolubilityNatural resource
A process for upgrading hydrocarbonaceous oil containing heteroatom-containing compounds where the hydrocarbonaceous oil is contacted with a solvent system that is a mixture of a major portion of a polar solvent having a dipole moment greater than about 1 debye and a minor portion of water to selectively separate the constituents of the carbonaceous oil into a heteroatom-depleted raffinate fraction and heteroatom-enriched extract fraction. The polar solvent and the water-in-solvent system are formulated at a ratio where the water is an antisolvent in an amount to inhibit solubility of heteroatom-containing compounds and the polar solvent in the raffinate, and to inhibit solubility of non-heteroatom-containing compounds in the extract. The ratio of the hydrocarbonaceous oil to the solvent system is such that a coefficient of separation is at least 50%. The coefficient of separation is the mole percent of heteroatom-containing compounds from the carbonaceous oil that are recovered in the extract fraction minus the mole percent of non-heteroatom-containing compounds from the carbonaceous oil that are recovered in the extract fraction. The solvent-free extract and the raffinate concentrates may be used directly or processed to make valuable petroleum, chemical or industrial products.

The present invention relates to a method in which grades of oil are refined according to their object from a feed oil. This method has a solvent extraction process that obtains an extracted oil, and a hydrogenation process that subjects the obtained extracted oil to hydrogenation process in the presence of hydrogen and a catalyst to obtain a hydrorefined oil. The solvent extraction conditions are selected by using the poly-aromatic concentration as an index for calculating the concentration of heptane insoluble components in the residue of the extracted oil obtained by the solvent extraction process that cannot be fractionally distilled.

Advisory controls of desalter system
ActiveUS20150361350A1Dewatering/demulsification with chemical meansLiquid separation auxillary apparatusDemulsifierFirst principle
The present invention concerns a method of providing advisory controls for a desalter system. The method allows a user to continuously monitor performance of the desalter system, to continuously monitor position of the emulsion band (or rag layer), to control the emulsion band using demulsifiers, and to recommend to users how to maintain optimal pressure drop at the mixing device of the desalter system. This is achieved by using a first principles based model combined with a sensor to measure the position, quality and size of the emulsion band. The first principles based model takes into account the geometry of the desalter system, physical properties of the crude oil and water, as well as the operating conditions. Thus, the method provides users with sensing of an emulsion layer through direct measurements and also gives recommendations on appropriate corrective actions to be initiated during upsets.

An apparatus and process is provided for improved asphaltene separation from heavy hydrocarbon or bitumen with low process complexity through mass transfer using solvent and counter-current flows, with three sections: an upper DAO / solid-asphaltene separation zone, a middle solvent mixing and segregation zone, and a bottom clarification zone. Solvent mixed with heavy hydrocarbon forms a process feed introduced to the process vessel's upper zone and exposed to counter-current solvent removing DAO from solid asphaltene particles in the feed, the particles fall through the middle zone and are mixed with introduced solvent, which introduced solvent segregates DAO-rich solution in the upper zone (for extraction from that zone) from solvent-rich mixtures in the middle mixing and lower clarification zones. Solvent flows and precipitate movement are controlled to optimize mass transfer in process, resulting in high DAO recovery and dry, solid asphaltene product.
