    Abstract: A method requires no sample preparation to determine not only whether a fuel contains drag reduce additive (DRA), but also the manufacturer(s) of the DRA. To date, there is no available method to quickly and easily perform this analysis. Only 60 microliters of sample are needed for the determination, which can be performed within two hours.

    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.

    IPC: C10G69/02

    Abstract: Embodiments of systems and methods to produce aviation fuel are disclosed. An example of a method to produce aviation fuel includes fractionating a renewable diesel feedstock in a fractionator to produce a C8− fraction, a C8-18 fraction, and a C18+ fraction. Additionally, the method includes providing the C8-18 fraction to an isomerization reactor to produce an aviation fuel product. The method includes supplying at least a portion of the C18+ fraction to a hydrocracking reactor to produce a hydrocracked product. The method further includes recycling at least a portion of the hydrocracked product to the fractionator for fractionating along with the renewable diesel feedstock.

    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: A test station assembly for monitoring a cathodic protection system of a buried or submerged structure includes a housing including an inner chamber a connector, and an opening. In addition, the test station assembly includes a pole to connect to the connector such that an electrical conductor extending through the pole and connected to a coupon assembly is configured enter into the inner chamber. Further, the test station assembly includes a face plate to attach to the housing to at least partially cover the opening and an electrically conductive test post to connect to the face plate. Still further, the test station assembly includes a cap to cover the test post outside of the inner chamber. The cap includes an internal passage to receive the test post therein, and an opening into the internal passage to receive a probe of a voltmeter therethrough to contact the test post.
