    Abstract: Methods and assemblies may be used for determining and using standardized spectral responses for calibration of spectroscopic analyzers. The methods and assemblies may be used to calibrate or recalibrate a spectroscopic analyzer when the spectroscopic analyzer changes from a first state to a second state, the second state being defined as a period of time after a change to the spectroscopic analyzer causing a need to calibrate or recalibrate the spectroscopic analyzer. The calibration or recalibration may result in the spectroscopic analyzer outputting a standardized spectrum, such that the spectroscopic analyzer outputs a corrected material spectrum for an analyzed material, and defining the standardized spectrum. The corrected material spectrum may include signals indicative of material properties of an analyzed material, the material properties of the material being substantially consistent with material properties of the material output by the spectroscopic analyzer in the first state.

    Abstract: Methods and systems for, among other embodiments, transporting renewable diesel (RD) through a pipeline, or a portion thereof, are provided. In certain embodiments, the method may include transporting the renewable diesel from a first pipeline terminal to a second pipeline terminal, the renewable diesel wrapped head and tail with a compatible diesel fuel. The method may also include restricting the transport of the diesel fuel in the pipeline to diesel fuel compositions having a first composition or first specification, the first composition or first specification characterized by a selected amount of the renewable diesel, or a component thereof, the selected amount being less than the selected amount allowed in a second target specification for the diesel fuel. The method may also include combining, at the second pipeline terminal, at least a portion of the mixed interface fraction stream with at least a portion of the diesel fuel fraction stream so as to produce a diesel fuel stream meeting the second target specification.

    Abstract: Assemblies and methods for monitoring the cathodic protection of underground or submerged structures may include a coupon assembly including a conductive test coupon and a reference electrode for determining the voltage potential difference of the protected structure without substantially interrupting surrounding current sources. The reference electrode may be at least partially covered with an electrolytic material in electrical contact with the surrounding environment via a plug including a porous material. A method of installation of the assembly may allow a single technician to install the coupon assembly using a probe rod without extensive on-site excavation. The coupon assembly may be configured to seat securely with the probe rod for stability during installation, and release from the probe rob when the probe rod is separated from the coupon assembly and withdrawn from the ground, leaving the coupon assembly at a preselected depth or preselected distance from the protected structure.

    Abstract: Systems and methods to provide renewable transportation fuels for internal combustion engines by converting renewable feedstocks into two or more intermediate hydrocarbon blend stocks and blending at least two of the two or more intermediate hydrocarbon blend stocks to produce the renewable transportation fuel. Methods and/or processes may include selecting sugar from a sugar source and introducing the sugar into one or more reactors. The sugar may be converted into an intermediate renewable hydrocarbon blend stock and sent to a separation unit to separate out an intermediate renewable gasoline unit. The process may include selecting and converting a lipid from a lipid source into a renewable diesel product. The renewable diesel product may be sent to a second separation unit to separate out renewable diesel and a low-grade naphtha. The low-grade naphtha and intermediate renewable gasoline may be blended to define a finished renewable gasoline.

    Abstract: Methods and systems of admixing hydrocarbon liquids from two or more sets of tanks into a single pipeline to provide in-line mixing thereof. In an embodiment of the in-line mixing system, hydrocarbon liquids stored in at least one tank of each of two or more sets of tanks positioned at a tank farm are blended into a blend flow pipe via in-line mixing and the blended mixture is pumped through a single pipeline. In one or more embodiments, the in-line mixing system employs a separate spillback or recirculation loop that is fluidly connected to each set of the two or more sets of tanks to control the flow of the hydrocarbon fluid/liquid from each set of tanks to the blend flow pipe. Associated methods of operating one or more embodiments of the system include regulation of spillback or recirculation loop flow rate and/or pressure to drive the actual blend ratio towards a desired blend ratio.
