Embodiments herein relate to systems and methods for identifying a plurality of components of a petroleum sample. Embodiments further relate to determining respective atmospheric equivalent boiling points (AEBPs) for respective ones of the plurality of components. Embodiments further relate to determining a boiling curve for the petroleum sample based on the respective AEBPs. Embodiments further relate to outputting an indication of the boiling curve for the petroleum sample. Other embodiments may be described or claimed.

Determination of petroleum component boiling temperatures

Systems and methods include a computer-implemented method for analyzing petroleum samples. Different boiling curves are received that are calculated for a petroleum sample using different analytical speciation techniques. The boiling curves include: 1) a detailed hydrocarbon analysis (DHA) is used for a speciation of light-end components of the petroleum sample; 2) a comprehensive 2-dimensional (2D) gas chromatography (GCxGC) is used for a speciation of a middle distillates range of the petroleum sample; and 3) a high-resolution mass spectrometry is used for a speciation of heavy-end components of the petroleum sample. A compositional coverage of the different analytical speciation techniques for the petroleum samples is determined using the different boiling curves. Each of the different analytical speciation techniques covers a different boiling range and produces a compositional model modeling a breakdown of components in the petroleum sample by carbon number, aromatic ring family, and heteroatom class.

Systems and methods include an aromatics complex (ARC), the ARC in fluid communication with a naphtha reforming unit (NREF) and operable to receive a reformate stream produced by the NREF, and the ARC further operable to separate the reformate stream into a gasoline pool stream, an aromatics stream, and an aromatic bottoms stream; and a hydrodearylation unit operable to receive heavy, non-condensed, alkyl-bridged, multi-aromatic compounds from the aromatic bottoms stream, the hydrodearylation unit further operable to hydrogenate and hydrocrack the heavy, non-condensed, alkyl-bridged, multi-aromatic compounds to produce a stream suitable for recycle to the NREF or the reformate stream, where the hydrodearylation unit is further operable to receive hydrogen produced in the NREF.

Two stage hydrodearylation systems to convert heavy aromatics into gasoline blending components and chemical grade aromatics

A process for producing one or more of benzene, toluene, or mixed xylenes may include combining one or more aromatic feed chemicals, one or more aromatic-based polymers, hydrodearylation catalyst, and hydrogen in a hydrodearylation unit to form a chemical product. The process may also include passing the chemical product out of the hydrodearylation unit, where the chemical product comprises one or more of benzene, toluene, and mixed xylenes. Additionally, a system for producing one or more of benzene, toluene, or mixed xylenes may include a mixing unit and a hydrodearylation unit. An aromatic feed stream and an aromatic-based polymer stream may be in fluid communication with a mixing unit. A mixing unit effluent stream may be in fluid communication between the mixing unit and the hydrodearylation unit. A chemical product stream may be in fluid communication with the hydrodearylation unit.

A system and a method is provided for calculating and assigning one or more indicative properties (e.g., cetane number, pour point, cloud point and/or aniline point) of a fractions of a crude oil sample based upon gas chromatographic simulated distillation data.

Characterization of crude oil by simulated distillation

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.
