    Abstract: Embodiments include systems and methods of in-line mixing of hydrocarbon liquids from a plurality of tanks into a single pipeline. 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 determining a ratio of a second fluid flow to a first fluid flow based on signals received from a tank flow meter in fluid communication with the second fluid flow and a booster flow meter in fluid communication with a blended fluid flow. The blended fluid flow includes a blended flow of the first fluid flow and the second fluid flow. The method further includes comparing the determined ratio to a pre-selected set point ratio thereby to determine a modified flow of the second fluid flow to drive the ratio toward the pre-selected set point ratio. The method further includes controlling a variable speed drive connected to a pump thereby to control the second fluid flow through the pump based on the determined modified flow, the pump being in fluid communication with the second fluid flow.

    Abstract: Systems and methods to vent a tank to enhance transporting asphalt when positioned in the tank may include connecting a vapor box to a tank. The vapor box may include one or more vents apertures and a valve associated with the one or more vent apertures and positioned to provide fluid flow between the interior of the vapor box and the exterior. The systems and methods may also include communication via a selector with the valve to cause the valve to switch between an open condition and a closed condition. The selector may be located remotely from the valve, and the systems and methods may also include communication with an indicator via one or more of the valve or the selector to provide an indication of one or more of the valve in the open condition or the valve in the closed condition.

    Abstract: Fuel oil compositions, and methods for blending such fuel oil compositions, to enhance initial compatibility and longer term stability when such fuel oil compositions are blended to meet IMO 2020 low sulfur fuel oil requirements (ISO 8217). In one or more embodiments, asphaltenic resid base stocks are blended with high aromatic slurry oil to facilitate initial compatibility such that low sulfur cutter stocks, e.g., vacuum gas oil and/or cycle oil, may be further blended therein to cut sulfur content while maintaining longer term stability. These fuel oil compositions are economically advantageous when used as marine low sulfur fuel oils because greater concentrations of high viscosity resids are present in the final blend.

    Abstract: Low sulfur fuel oil blend compositions and methods of making such blend compositions to increase the stability and compatibility of LSFO blends having paraffinic resids that are blended with distillates and/or cracked stocks of higher asphaltenes and/or aromatics content. In one or more embodiments, distillates and/or cracked stocks that incrementally reduce the initial aromaticity of the distillate or cracked stock with the highest aromaticity are sequentially blended prior to resid addition. Such incremental reduction and sequential blending have been found to provide a resulting low sulfur fuel oil blend that is both compatible and stable.

    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.
