A method and a system for separating and recovering an entire liquid hydrocarbon sample using an accelerated solvent extractor is disclosed. In the method, a filter is inserted into a bottom portion of an extraction cell of the accelerated solvent extractor. An adsorbent is activated via heating in a furnace and then cooled. At least a portion of the adsorbent is then inserted into the extraction cell and a liquid hydrocarbon sample is introduced into the extraction cell on top of the adsorbent. The extraction cell comprising the sample is placed in a cell tray of the accelerated solvent extractor and the saturate, aromatics, and resins fractions of the sample are sequentially extracted using first, second and third solvents, respectively. The entire liquid hydrocarbon sample is extracted as a result of the method.

A method and a device for preparing a vanadium-containing combustible in a de-asphalting device. In this way, a vanadium-containing combustible is supplied to a de-asphalting unit via a supply line in a de-asphalting device, wherein the vanadium-containing combustible supplied into the de-asphalting unit forms a first mass flow and a substantially de-asphalted combustible is discharged from the de-asphalting unit via a discharge line. A bypass line is connected to the supply line, wherein, via the bypass line, a second mass flow of the vanadium-containing combustible is directed past the de-asphalting unit in parallel to the first mass flow and supplied to the discharge line, such that a combined mass flow is formed in the discharge line.

Techniques provided herein relate to regulating at least one operating parameter of a paraffinic froth treatment (PFT) operation and controlling the quality of the produced bitumen in response to a determined concentration of at least one residual metal in a PFT process stream. Determination of the residual metal concentration is based on acquired NIR spectral measurements of the PFT process stream. An alkaline agent dosage in primary extraction operation can be for example regulated in response to a difference between a determined calcium concentration and a calcium concentration specification.

Embodiments of the present invention are generally related to a system and method to remove hydrogen sulfide from sour water and sour oil. Particularly, hydrogen sulfide is removed from sour water and sour oil without the need for special chemicals, such as catalyst chemicals, scavenger chemicals, hydrocarbon sources, or a large-scale facility. The system and method in the present invention is particularly useful in exploratory oil and gas fields, where large facilities to remove hydrogen sulfide may be inaccessible. The present invention addresses the need for safe and cost-effective transport of the deadly neurotoxin. Particular embodiments involve a system and method that can be executed both on a small and large scale to sweeten sour water and sour oil.

A method for refining fuel oil comprises subjecting fuel oil to an extraction treatment with an extraction agent to extract a light component from the fuel oil, so as to obtain a light oil mixture containing the light component of the fuel oil and the extraction agent. The extraction agent is selected from the group consisting of a matter composed of oil and miscible with the light component of the fuel oil, a non-polar compound in a gaseous state at the room temperature and atmospheric pressure, and a combination thereof. The extraction agent is in a liquid state during the extraction treatment.
