Systems and methods to provide low carbon intensity (CI) transportation fuels through one or more targeted reductions of carbon emissions based upon an analysis of carbon emissions associated with a combination of various options for feedstock procurement, feedstock refining, processing, or transformation, and fuel product distribution pathways to end users. Such options are selected to maintain the total CI (carbon emissions per unit energy) of the transportation fuel below a pre-selected threshold that defines an upper limit of CI for the transportation fuel.

A method for preparation of a reagent for reducing hydrodynamic drag of a turbulent flow of liquid hydrocarbons in pipelines, characterized by a high polymer content of at least 75 wt %, including mixing a 0.1-1.5 mm polymer reducing the hydrodynamic drag of a turbulent flow of liquid hydrocarbons with polymer non-solving solvents. The prepared product is a commodity form of the reagent with a high polymer content of at least 75 wt % used to reduce the hydrodynamic drag of the flow of liquid hydrocarbons in pipelines. The product prepared according to the described method is injected into the flow of hydrocarbon fluid transported through the pipeline using the injection apparatus that mechanically moves the product using a screw auger or screw feeder.

A real time additive processing system for crude oil or refined fuel products is coupled to a fuel transport line that transfers fuel from one storage tank to another storage tank. The fuel additive processing system includes a fuel additive storage tank coupled to a liquid conduit having a liquid pump with a speed/stroke controller that regulates the liquid pump. The liquid conduit is coupled to the fuel transport line at a fuel additive injection nozzle. The fuel additive processing system also includes a flow rate transmitter and a chemical or physical property analyzer coupled to the fuel transport line downstream of the additive injection nozzle. The fuel additive processing system includes a flow controller that communicates with the liquid pump speed/stroke controller, flow rate transmitter and chemical or physical property analyzer. A remote system allows selective control of the flow controller.

This disclosure describes formulations and methods for dust control, for example, coal topping, a term which refers to the application of liquid products to the top of coal loads, such as those in open topped coal hopper railcars as commonly used today to transport coal. Disclosed herein are asphalt-based emulsion formulations that accomplish dust control during industrial operations in which dust handling is required.

The present disclosure generally relates to systems and methods utilizing regenerative agriculture for the procurement, production, refinement and/or transformation of low carbon intensity transportation fuels, including low carbon intensity biodiesel and/or renewable diesel, low carbon intensity biogasoline, low carbon intensity aviation, marine and kerosene fuels as well as fuel oil blends, low carbon intensity ethanol, and low carbon intensity hydrogen, that may be beneficially commercialized directly to consumers. In further aspects, the systems and methods of the present disclosure advantageously generate low carbon intensity comestibles, including sustainably-sourced meal and/or feed. The disclosed systems and methods may be utilized and optimized such that the resulting fuels and foodstuffs are characterized by a reduction in greenhouse gas production and a diminution in the fertilizer, pesticide and water required for producing the associated crop feedstocks.

The lifetime of artificial lift systems, such as progressing cavity pumps (PCPs), used to transport aqueous slurries which contain fine particles, e.g. coal fines, may be prolonged by incorporation of at least one dispersant in the slurries. The dispersants act to inhibit or prevent the fine particles from agglomerating to plug the artificial lift intake and/or inhibit or prevent the agglomerated coal fines settling above the artificial lift system. The dispersant may also improve the lubricity of the slurry.

A stabilized paraffin inhibitor/pour point depressant (PI/PPD) product formulation is described which includes a copolymer having a monomer selected from the group consisting of alkyl acrylate polymers, alkyl methacrylate polymers, and combinations thereof, where the copolymer comprises vinyl acetate and the product includes an ethylene-based copolymer. The presence of the vinyl acetate stabilizes the product to prevent or inhibit the ethylene-based copolymer from separating out of the product. The product is useful to reduce paraffin deposition and/or improve flow characteristics of petroleum fluids, such as crude oil.

Methods and systems for manufacturing emulsified fuel include: adding surfactant to fuel; blending the surfactant and fuel together in a first mixing chamber for a first mixing period; subjecting the blended surfactant and fuel mixture to a dwell period following the first mixing period; introducing water into the blended surfactant and fuel mixture following the dwell period; and blending the surfactant, fuel and water together in a second mixing chamber for a second mixing period. The surfactant is selected to exhibit an HLB rating in the range of 8.75 to 8.83.

A fuel oil composition of the present disclosure may comprise (i) a solid hydrocarbonaceous and/or solid carbonaceous material, wherein the material is in particulate form, and wherein at least about 90% by volume (% v) of the particles are no greater than about 20 microns in diameter; and (ii) a liquid fuel oil; wherein the solid hydrocarbonaceous and/or solid carbonaceous material is present in an amount of at most about 30 by mass (% m) based on the total mass of the fuel oil composition. The present disclosure further relates a process for the preparation of this fuel oil composition, a method of changing a grade of a liquid fuel oil, and a method for adjusting the flash point of a liquid fuel oil.

The present technology is related to imide containing quaternary ammonium salts having a hydrocarbyl substituent of number average molecular weight less 300, and additive packages having such quaternary ammonium salts and improved stability.
