    Abstract: Embodiments include systems and methods of in-line mixing of hydrocarbon liquids and/or renewable liquids from a plurality of tanks into a single pipeline based on density or gravity. According to an embodiment, a method of admixing hydrocarbon liquids from a plurality of tanks into a single pipeline to provide in-line mixing thereof includes initiating a blending process. The blending process including continuously blending two or more liquids over a period of time, each of the two or more liquids stored in corresponding tanks, each of the corresponding tanks connected, via pipeline, to a blend pipe thereby blending the two or more liquids into a blended liquid. The method further includes determining a density of each of the two or more liquids to be blended during the blending process. The method includes, in response to a determination that the blend process has not finished and after the passage of a specified time interval, determining an actual blend density of the blended liquid, via a blend sensor connected to the blend pipe, the blended liquid flowing through the blend pipe and in contact with the blend sensor, and the specified time interval less than a total duration of the blending process. The method includes determining an actual blend density of the blended liquid, via a blend sensor connected to the blend pipe, the blended liquid flowing through the blend pipe and in contact with the blend sensor, and the specified time interval less than a total duration of the blending process; comparing the actual blend density with a target blend density; and in response to a difference, based on the comparison, of the actual blend density and target blend density determining a corrected ratio based on each density of the two or more liquids, the actual blend density, and the target blend density and adjusting, via one or more flow control devices, flow of one or more of the two or more liquids, based on the corrected ratio.

    Abstract: In a hydrocracking process, the hydrocarbon feed is processed by a guard reactor operating at maximum severity temperatures. The processing in the guard reactor maximizes the removal of metals and performs hydrodenitrogenation steps and hydrodesulfurization steps. The demetallized and partially desulfurized and denitrogenized hydrocarbon feed is then sent to a treating reactor for further hydrodenitrogenation and hydrodesulfurization before being sent further downstream for further hydrocracking processing.

    Abstract: This process operates a continuous catalyst regeneration (CCR) system for reforming comprising the steps of: (a) introducing a coking additive selected from the group consisting of organo sulfur, organo nitrogen and oxygenate compounds into a hydrocarbon feedstock; (b) continuously introducing the hydrocarbon feedstock and coking additive of step (a) into a CCR reforming unit; (c) continuously introducing hydrogen into the CCR reforming unit; (d) continuously operating the CCR reforming unit to produce coke and a hydrocarbon rich, hydrocarbon stream; (e) continuously operating the CCR reforming unit to burn off excess coking additive; and (f) continuously recovering the hydrocarbon rich hydrocarbon stream.

    Abstract: Assemblies and methods to enhance a refining process associated with a refining operation may include supplying a material to first processing units associated with the refining operation. The assemblies and methods also may include conditioning unit material samples, and analyzing the samples via one or more spectroscopic analyzers. The assemblies and methods further may include prescriptively controlling, via one or more refinery process controllers, based at least in part on the unit material properties, the refinery processing assembly, so that the prescriptively controlling results in causing the refining process to produce intermediate materials, the unit materials, and/or the downstream materials having properties within selected ranges of target properties, thereby to cause the refining process to achieve material outputs that more accurately and responsively converge on one or more of the target properties.
