摘要： A crude oil feedstream is treated to remove or reduce the content of known undesired heteroatomic and polynuclear aromatic compounds containing nitrogen and sulfur by contacting the feedstream with one or more solid adsorbent materials selected from attapulgus clay, alumina, silica gel and activated carbon in a mixing vessel for a time that is sufficient to optimize the adsorption of the undesired compounds from the crude oil, subjecting the mixture to atmospheric flash distillation and then to vacuum flash distillation to recover presorbed boiling ranges of products having a lowered content of the undesired compounds, and preferably regenerating at least a portion of the solid adsorbent material for reuse in the process.

摘要： A process is described for reducing the total acid number of a refinery feedstock. In one embodiment, refinery feedstock containing naphthenic acids is contacted with an effective amount of solid catalyst in the presence of an aqueous caustic base, wherein the caustic base is sodium hydroxide or potassium hydroxide, for a period of time sufficient to neutralize at least a portion of the naphthenic acids in the feedstock. Thereafter, the aqueous phase is separated from the neutralized refinery feedstock. In another embodiment catalyst is pretreated with a caustic base solution and contacted with refinery feedstock to reducing the total acid number.

摘要： A hydrocarbon feedstock is hydrocracked in a hydrocracking zone and the effluent is fractioned to recover a light fraction, a middle fraction containing aromatic compounds and a heavy fraction. The heavy fraction is recycled to the hydrocracking zone for further hydrocracking. The middle fraction is introduced to an aromatic separation zone. A product stream is recovered from the aromatic separation zone comprising a middle fraction having a reduced content of aromatic compounds as compared to the middle fraction recovered from the fractionator. Aromatics from the aromatic separation zone are recycled to the hydrocracking zone for further hydrogenation and cracking.

摘要： A process for stabilization of heavy hydrocarbons to reduce sludge formation in storage tanks and/or transportation lines and to enhance the hydrocarbon yield includes mixing a paraffinic or heavy naphtha solvent having carbon numbers in the range 10 to 20 with the feedstock to solvent-flocculate a relatively small, predetermined portion of asphaltenes present in the feedstock, separating and flashing the sediment to recover a light hydrocarbon fraction, flashing the heavy hydrocarbon/solvent phase and recycling the solvent to stabilize the heavy hydrocarbons without significantly affecting the yield of valuable products.

摘要： A system and a method for determining one or more distillation temperatures for one or more given distillation weight percentages of a crude oil sample are provided, which can be used to produce a simulated distillation curve. Simulated distillation temperatures of crude oil samples are assigned as a function of density and data derived from UV/Visible spectroscopy measurement of the crude oil samples.

摘要： Initial high sulfur levels of a hydrocarbon feedstock are reduced to desired low levels without the need for integration of substantial new equipment or hardware with existing hydroprocessing reactors. Ionic liquids are utilized as organic sulfur extraction agents and are added to and mixed with the hydrocarbon feedstock containing organosulfur compounds in, or upstream of, an existing cold separator vessel. The ionic liquid and hydrocarbon mixture is maintained in contact under conditions which promote the formation of ionic sulfur-containing derivatives that are soluble in the ionic liquid to be formed, thereby enabling extractive removal and separation of the organosulfur compounds from the feedstock.
