HYDROCARBON UPGRADING METHOD AND APPARATUSCROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims benefit of U.S. provisional patent application Serial No. 63 / 652,315 filed May 28, 2024 and entitled “HYDROCARBON UPGRADING METHODS AND APPARATUS," which is hereby incorporated herein by reference in its entirety for all purposes.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

[0002] Not applicable.TECHNICAL FIELD

[0003] The present disclosure relates generally to methods and compositions for the upgrading of nonaqueous fluids. More particularly, the present disclosure relates to methods and compositions for reducing impurities present in mixtures of nonaqueous fluids. Still more particularly, the present disclosure relates to methods and compositions for reducing impurities in hydrocarbons obtained during oilfield production processes.BACKGROUND

[0004] Significant quantities of water are present in hydrocarbon reservoirs. When brought to the land surface during oil, gas, and coalbed methane production, the water, either naturally-occurring or injected as a method to enhance production, is termed produced water. Produced water is currently managed through processes such as recycling, treatment and discharge, spreading on roads, evaporation or infiltration, and deep well injection. In conventional oil and gas wells, produced water generally consists of naturally-occurring brine present in the reservoir and water injected nearby to push the hydrocarbon deposit into production wells. In continuous or unconventional resources, such as shale gas or tight oil, fracturing fluid and a solid material (e.g., proppant) are injected into the reservoir under very high pressure in order to create fractures to increase rock porosity and permeability. In this scenario, the produced water is usually a mixture of the injected fluids with formation brines in the reservoir.

[0005] The quality of produced water is variable, ranging in salinity from similar to that of drinking water to several times more saline than sea water. Various constituents can be contained in produced water from petroleum or coal reservoirs, including dissolved salt, petroleum and other organic compounds, suspended solids, trace elements,bacteria, naturally-occurring radioactive materials (NORM), and anything injected into the well. Because of the considerable variability in water chemistry and the potentially large volumes involved, the management of produced water is an important and complex issues that usually increases the unit cost of oil production.

[0006] For example, costs increases are in part because produced water must be separated from the oil, treated, and disposed of properly. Furthermore, sellable crude oil must comply with certain product specifications, including the amount of basic sediment and water (BS&W) and salt.

[0007] Produced water may be produced as “free” water (i.e., water that will settle out fairly rapidly) and / or it may be produced in the form of an emulsion. A regular oilfield emulsion is a dispersion of water droplets in oil. Emulsions can be difficult to treat and may cause several operational problems in wet-crude handling facilities and gas / oil separating plants. Emulsions can create high-pressure drops in flow lines, lead to an increase in demulsifier use, and sometimes cause trips or upsets in wet-crude handling facilities. The problem is usually at its worst during the winter because of lower surface temperatures.

[0008] Nonaqueous fluids such as hydrocarbons often are treated to remove any associated impurities in order to meet crude specifications for transportation, storage, and export and to reduce detrimental effects such as corrosion and catalyst poisoning in downstream processing facilities. An ongoing need exists for methods and compositions that facilitate the removal of these impurities from oleaginous fluids.

[0009] Further, with sustainability being a desired goal, tremendous progress in biobased production routes from renewable raw materials to commercial goods continues to occur. Of particular interest is the formation of higher value chemicals from what are termed “platform molecules.” Herein platform molecules refer to bio-based or bioderived chemicals whose constituting elements totally originated from biomass and could be used as building blocks forthe generation of commodity and refined chemicals. An ongoing need also exists for novel methods utilizing platform molecules in the production of commodity and refined chemicals.BRIEF SUMMARY OF THE DISCLOSURE

[0043] In one or more aspects, a PAD of the type disclosed herein is contacted with a NAA. Nonlimiting examples of aqueous fluids that may be a component of the NAA can include fresh water, surface water, ground water, produced water, sea water, saltwater, brine, or combinations thereof. In some aspects, the nonaqueous fluid is a component of the mixture or is a nonaqueous phase of a solution having multiple phases. In some aspects, the nonaqueous fluid includes, but is not limited to: crude oil, refined oil products, fuels such as gasoline, diesel, kerosene, heating oil, fuel oils, olefins, alkanes, paraffins, alkenes, aromatics such as BTX, alcohols such as ethanol, bio-based oils such as vegetable oil, which include soybean, rapeseed, canola, safflower, sunflower, nut oils, palm oil, citrus oils, oil-based muds, and synthetic muds. In some aspects, the NAA comprises hydrocarbons or oleaginous fluids.

Contacting of the PAD with the NAA may be carried out using any suitable methodology.

[0044] In one or more aspects, a quantity of aqueous fluid (e.g., distilled water) may be contacted with the NAA prior to or subsequent to addition of a PAD. The NAA with the added quantity of aqueous fluid may be agitated (e.g., stirred, mixed) to improve transfer of ionic impurities to the aqueous fluid and facilitate removal of the impurities. The quantity of water contacted with the NAA will depend on a variety of factors such as the impurity level of the NAA and the amount of NAA and may be determined by one or ordinary skill in the art.

[0045] In one or more aspects, contacting of the PAD with the NAA may comprise mixing the PAD and NAA, with or without added aqueous fluid, using mixing equipment (e.g., a jet mixer, re-circulating mixer, a batch mixer, a blender, a mixing head of a solid feeding system) and then allowing the mixture to separate. Any container(s) that iscompatible with the components and has sufficient space can be used for mixing may be used.

[0046] In one or more aspects, mixing of the PAD and NAA can be on-the-fly (e.g., in real time or on-location). In some aspects, the mixing equipment may be disposed on one or more trucks as will be apparent to those of ordinary skill in the art.

[0047] Without wishing to be limited by theory, the PAD may facilitate the removal of cations from the NAA and consequently the amount of undesirable materials present in the nonaqueous fluid component of the NAA. The undesirable materials can be removed into the aqueous phase for separation from the nonaqueous fluid component of the NAA. In one or more aspects, the PAD facilitates the removal of metals from the NAA.

[0048] In one or more aspects, a PAD of the present disclosure is utilized in the purification of one or more hydrocarbons having an aqueous component. For example, the PAD may be contacted with a hydrocarbon obtained from a wellbore that contains some amount of nonaqueous fluid having an aqueous component (i.e. , NAA) and some amount of impurities. For example and with reference to Figure 1 , a method for reducing impurities in an unprocessed hydrocarbon 100 is schematically depicted. In some aspects, an unprocessed hydrocarbon 110 may be suitable for use in some applications and communicated via conduit 155 to a sales pipeline. In another aspect, the unprocessed hydrocarbon 110 is conveyed via conduit 115 to a processing tank 140 which is fluidly communicated via conduit 118 with a container 130 having a PAD disposed therein. The processing tank 140 may have the means to mix the unprocessed hydrocarbon 110 and PAD (e.g., a static or active mixer, etc.) and allow the water to separate from the unprocessed hydrocarbon. While shown as being combined in the processing tank 140, the PAD can also be combined with the unprocessed hydrocarbon 110 upstream of the processing tank 140 to mix prior to entering the processing tank 140. In some aspects, separated water can be conveyed via conduit 145 to any suitable process such as a storage tank, salt water disposal (SWD) system or recycling while the low water oil and low BS&W is conveyed via conduit 165 to a sales pipeline. It is to be understood that any hydrocarbon conveyed to the sales pipeline may be used without further processing or may be subjected to any number of additional processes to meet one or more user and / or process goals.

[0049] In one or more other aspects and with reference to Figure 2, a method for reducing impurities in an unprocessed hydrocarbon 200 is schematically depicted. In some aspects, an unprocessed hydrocarbon 210 may be suitable for use in some applications and fluidly communicated via conduit 265 to a sales pipeline. In another aspect, the unprocessed hydrocarbon 210 is conveyed via conduit 215 to a processing tank 220, which is in fluid communication via conduit 219 with a container 240 having a PAD disposed therein. The processing tank 220 may have the means to mix the unprocessed hydrocarbon 210 and PAD 240 and allow the water to separate from the unprocessed hydrocarbon 210. While shown as being combined in the processing tank 220, the PAD can also be combined with the unprocessed hydrocarbon 210 upstream of the processing tank 220 to mix prior to entering the processing tank 220. In some aspects, the water-hydrocarbon mixture is conveyed via conduit 218 to an electrodemulsification process such as an electrocoagulation unit 230 via conduit 218, which aids in coalescing any water to help remove water dispersed within the oil.

[0050] Electrocoagulation (EC) is an oil removal technology where metal ions (e.g., Fe, Al) are dissociated by applying an electric current, which hydrolyzes, hydroxy-metal species, and causes flocs to develop that remove pollutants from the wastewater. In an aqueous medium, when an electric current is applied, metallic ions are produced at the anode and hydrogen gas at the cathode. The produced hydrogen gas creates slight turbulence in the reactor and interacts with the pollutants. Hydrogen gas bubbles bond with pollutants and reduce their relative specific gravity. EC may result in the removal of natural organic matter, arsenic, hardness , phosphate and fluoride. Water may exit the EC 230 via conduit 225 to any suitable process such as a storage tank, salt water disposal (SWD) system or recycling while the low water oil and low BS&W is conveyed via conduit 265 to a sales pipeline.
