Definitions

  • the present invention is in the field of mining, reclamation and recycling. Specifically, the present invention provides methods for retrieving organics, including petroleum products and byproducts, crude oil, and the recovery and recycling of organics-containing products, such as asphalt as well as the resulting recycled materials. More specifically, the present invention relates to a hybrid crude oil and methods of making the same using petroleum-based waste stream products.
  • Asphalt is a universal raw material used for roadways, parking lots and other surface treatments.
  • the asphalt material is generally a composition of minerals including aggregate and sand or stone dust and an asphalt binder. Additionally, novel asphalt mixtures include various substitutes for the aggregate (coarse and fine) including: glass that been reduced in size, used tires, and other reclaimed materials.
  • the asphalt binder is basically the glue that binds the mineral or aggregate ingredients such that they are solid under normal operating or environmental temperatures but l iq u id o r semi-liquid under elevated temperatures, such as 300-400° F.
  • Another product related to the commonly known term as asphalt is roofing shingles, composed of similar components including aggregate, asphalt binder, and fiberglass.
  • a typical asphalt composition contains a general ratio of materials as follows: coarse aggregate including minerals or stone, that have been reduced in size, having particle sizes in the range from about 1/8 to 1 inch, or 70-85% of volume, fine aggregate including compositions of stone dust that has been reduced in size, glass that has been reduced in size, sand or other small sized filler, or 10-20% of volume, asphalt binder, a blend of petroleum refinery product (byproduct) that can be further modified to achieve certain asphalt mixtures or grades, about 10% of volume, and miscellaneous ingredients including trapped air (voids) and moisture.
  • a typical asphalt mixture is the blending of the coarse and fine aggregate with the asphalt binder. However, in the blending process, some trapped air is normally also included.
  • the amount of trapped air and the coating and bonding of the asphalt binder to the aggregate determines the quality and grade of the final asphalt product.
  • the asphalt composition is subjected to elevated temperature (about 300-400°F) and uniformly mixed such that a uniform blending of components is achieved.
  • This hot mixture is bonded by the phase change of the asphalt binder from a semiliquid to a solid as the mixture cools to a lower temperature or ambient temperature.
  • the semi-liquid asphalt binder coats the coarse and fine aggregates, the final asphalt mixture is blended to meet the requirements of the needed final product.
  • Asphalt mixtures are required to meet Department of Transportation specifications based upon application location, environmental and temperature ranges and other requirements.
  • the various grades of asphalt are based upon the aggregate size (coarse and fine), content and percentages of the added components including binder. These asphalt grades created by their respective asphalt binders, screened aggregate particle sizes, compaction forces on the mixture and vibratory rolling to further orientate the final asphalt composition prior to solidification.
  • the asphalt binder applied is a form of thermoplastic that solidifies as the temperature is reduced from the asphalt blending temperature (300-400 °F) to the final product application temperatures (-60 to 160 °F). These temperature ranges affect the temperature change rate or thermal gradient of the solidification process and this affects the final product compaction ratio, density and mechanical properties.
  • the final asphalt product performance factors are based upon these components, the mixture ratios and application methods.
  • the asphalt binder is phase changed from a solid at ambient temperatures to a semi liquid or liquid state at elevated temperatures (a plastic state or high viscosity state) that coats the coarse and fine aggregates and fills the voids of the mixture. Aggregate uniformity coating issues occur with the semi liquid asphalt binder because it cannot be thoroughly liquid. After a certain elevation in temperature, the asphalt binder burns or degrades. This aggregate coating capability is an important aspect of achieving higher grade asphalts. It would be desirable to coat the aggregate in an improved manner.
  • the lower temperature of the contact surface changes the asphalt binder back from a semiliquid state to a solid. This becomes the desired asphalt final product.
  • the coarse and fine aggregate compositions, mixture ratios and asphalt binder blends may further improve the asphalt mixture and final asphalt product properties that may provide an improved life cycle, operating temperature exposure characteristics, weight load bearing properties, surface coefficient of friction characteristics and other desired properties.
  • the current methods for recycling asphalt typically take certain percentages of "millings” or scrapped/salvaged asphalt from an existing, aged or degraded asphalt surface and blend a small percentage of these millings into a virgin mixture of asphalt (a blend of 25% millings to 75% virgin asphalt is a normal practice). These recycling methods provide a means of recovering small percentages of the "used” or "salvaged” asphalt for recycling back into a new asphalt. As a general rule, approximately 10-30% of millings can remixed with virgin asphalt. This is because the new asphalt mixture is degraded with the addition of aged millings because it does not blend as uniformly as virgin materials.
  • Elseifi ef a/., U.S. Patent Publication 2014/0299018 generally describe a process for separating constituents of an asphalt-based material including at least asphalt and one solid non-asphalt material by shredding the asphalt-based material to form a shredded material mass.
  • an asphalt binder at an elevated temperature is added to absorb the recoverable asphalt binder from the shredded material. This produces a 30-40% increase in the binder volume, i.e., the recovered binder from the shredded material.
  • Kotefski etai U.S. Serial No. 15/355,487, filed November 18, 2016, the disclosure of which is herein incorporated by reference, generally teach methods to reclaim or recycle asphalt or asphalt components to produce reusable asphalt or asphalt components by adding the asphalt or asphalt components to a solution at a temperature higher than the melting temperature of the asphalt binder.
  • the solution may be at least 300°F, 325°F, 350°F or 400°F or so, and the solution may be an oil or petroleum based solution or any other suitable solution in which the asphalt binder is soluble. In some instances, the solution may be virgin motor oil or recycled motor oil or used motor oil. It is desirable to provide new and improved methods to reclaim or recycle asphalt to produce reusable asphalt and asphalt components.
  • reusable asphalt and asphalt components that have the same physical properties of virgin asphalt.
  • the aggregate or minerals of the asphalt are not physically altered in size, shape, or profile.
  • Franzen etai U.S. Serial No. 13/833,091, filed on March 15, 2013, generally describe a method of creating a processed asphalt suspension composition where the asphalt shingle material is reduced down to a particular size fine enough to effectively reuse the recycled shingle material into a new mixture of this recycled shingle material and the addition of virgin asphalt or an asphalt suspension composition. That is, the granules, fiberglass or other mineral components in the asphalt shingles are reduced to a mesh fine enough to be incorporated into newly manufactured products.
  • Franzen starts the process by grinding both the asphalt with the various minerals and filler materials, to form a recycled shingle material of approximately 1 cm in size, which is then added to, and mixed with hot virgin asphalt.
  • the mixture is then sent to a wet grinding process to both reduce the particle size of the mineral particles but to fully incorporate the asphalt from the recycled ground shingle material into the virgin asphalt.
  • the wet grinding process further reduces the size of the mineral particles to 200 microns from the initial reduction of 1 cm.
  • This wet grinding process is a mechanical deformation means of reducing, crushing or pulverizing the mineral components of the recycled shingle material down to a size of 200 microns and well as a means of incorporating the asphalt from the recycled ground shingle material into the virgin asphalt.
  • the wet grinding process creates a new mixture of ground shingle material and virgin asphalt, termed a processed asphalt suspension.
  • the processed asphalt suspension is a mixture of the pulverized recycled single material and additional virgin asphalt or an asphalt paste containing pulverized minerals.
  • Franzen as representative of conventional processes, does not permit the mining, that is the retrieval, removal, or recovery of the original (/.e., initial or native) constituent components of the asphalt shingle material, in terms of size, shape, or profile.
  • petroleum-containing materials include, for example: roofing shingles, pavement asphalt, tar sands, oil sands, shale, contaminated soils, and other petroleum-containing materials.
  • Crude oil is a natural product provided by various reserves on earth.
  • This natural product can be processed or distilled into byproducts, such as gasoline, kerosene, plastics, asphalt for roofing shingles, asphalt binder for asphalt pavement, and numerous other products. While gasoline and kerosene are burned as a fuel source, plastics, asphalt for roofing shingles, and asphalt binder for asphalt pavement become waste stream products after their useful life.
  • Each of these exemplary waste stream products creates a manmade pollution or waste stream on a continuous basis because crude oil or petroleum-based byproducts are a needed commodity and continue to be in great demand by consumers.
  • Oil does not dissolve in water. It lasts a long time and sticks to everything from beach sand to bird feathers. Oil and petroleum products are toxic to people, wildlife, and plants. One quart of motor oil can pollute 250,000 gallons of water, and one gallon of gasoline can pollute 750,000 gallons of water. Oil that leaks from cars onto roads and driveways is washed into storm drains, and then usually flows directly into a lake or stream. Used motor oil is the largest single source of oil pollution in lakes, streams, and rivers. Americans spill 180 million gallons of used oil each year into the nation's waters. This is about 16 times the amount spilled by the Exxon Valdez in Alaska. Reference is made to https://www.mass.gov/guides/education-in-nonpoint-source-pollution- prevention.
  • waste stream products are created by the industry but after their useful life they become an unneeded waste stream that create significant ecological, environmental, or pollution issues.
  • Plastics industry has a plastics waste stream comprised of various plastics.
  • roofing industry has a roofing waste stream composed of asphalt roofing shingles or commonly called roofing shingles, which is a composition of asphalt (or asphalt binder), fiberglass, and stones or aggregates as a solid composition.
  • Asphalt pavement industry has an asphalt pavement or millings waste stream which is a solid composition of asphalt binder and various sized aggregates, minerals, glass, and sands.

  • Asphalt is the bituminous binder or “glue” for roofing shingles. It is similar to asphalt binder but its chemistry is designed so that it is malleable instead of being hard for load bearing as in the asphalt pavement.
  • Elevated temperature represents a temperature of the oil-based solution at or above the melting or phase-change temperature for a petroleum-based coating that causes the petroleum-based coating to liquify and dissolve into a liquid oil-based solution or a hybrid crude oil.
  • the elevated temperature ranges between approximately 300°F to approximately 400 °F.
  • Waste stream product is a product that has no reuse or disposal solution after its useful life expires.

At ambient temperatures, this liquid oil-based solution is inert to the petroleum- based coating of the petroleum-containing material. As the oil-based solution is heated at, or above the melting or phase-change temperatures (“elevated temperature”) of the petroleum-based coatings, the oil-based solution acts as a solvent to the petroleum-based coatings and becomes able to dissolve the petroleum-based coatings into the oil-based solution. Within the process described, the oil-based solution after the initial (or first) dissolution of the petroleum-based coating from the petroleum-based material, creates a hybrid crude oil.
  • hybrid crude oil within the process described can be referenced as either a hybrid crude oil or as an oil-based solution, until such time as the extracted hybrid crude oil or oil-based solution from the described process has reached a desired concentration or mixture ratio of oil-based solution and petroleum- based coating is achieved.

Upon achieving the desired concentration of petroleum-based coating dissolved into the oil-based solution, the entire solution is then referred to as hybrid crude oil.

  • This solvent/binder mixture includes the asphalt binder that is small enough or loose enough to be carried into the binder/solution mixture.
  • the amount of asphalt binder or petroleum-based coating able to dissolve into the solvent is based upon the amount of rinses and how well the asphalt millings were reduced in size. The finer the breakdown the more broken asphalt binder surface area is exposed. In turn, the greater the amount of aggregate surface area exposed, the more the solvent is able to break down the aggregate asphalt binder coated surfaces and loose asphalt binder particulate.
  • the petroleum-based coating is in a solid state and solvent rinses provide a partial removal of the petroleum-based coating because the removal process is in a series of laminations. As each lamination is removed consecutively, the solvent removal of the petroleum-based coating approaches a complete removal of the petroleum-based coating from the petroleum-based material. This consecutive rinsing with solvent is costly and cost prohibitive.

  • Binder Coated Coarse Aggregate Large and medium sized aggregate with a significant asphalt binder coating or petroleum-based coating may be obtained. Each large and medium aggregate is coated with the residual asphalt binder that was not removed from the solvent cleaning operation performed in the automated parts washer. Thus, asphalt binder coated aggregate from the used asphalt millings are provided.
  • Binder Coated Fine Aggregate are of special value in the asphalt industry. They may be used directly in other products such as crack fillers, asphalt repair mixtures, surface texture treatments, etc. These fine aggregates are the sand and stone dust of asphalt. They are the smaller particulate of the aggregate composition and are the most difficult to uniformly coat with asphalt binder or a petroleum-based coating.

Thus, the methods described herein provide asphalt binder coated fine aggregate, a new commodity, useful in the asphalt, roofing, surface texture and other applications.
  • Binder/Solvent or Petroleum-Based Material Sludge from the automated parts washer As the asphalt or petroleum-based material that has been reduced in size, is washed in the automated parts washer, the residual asphalt binder/solvent sludge or petroleum-based material/solvent sludge is further processed by the automated parts washer. This is a standard solvent washing process in which the solvent is evaporated from the binder/solvent sludge or petroleum-based material/solvent sludge, and the solvent is reclaimed via cooling coils and liquefied for reuse. The remaining binder/solvent mixture component is asphalt binder. The remainder of the petroleum-based material/solvent sludge is petroleum product. Thus, the methods described herein provide for recovering asphalt binder. This asphalt binder may have small traces of the solvent. Hence, the asphalt binder may be further processed to purify the asphalt binder into the desired asphalt binder grade or mixture.

Thus, the amount of oil needed to process the large and medium aggregate is reduced by factors of 500% or more. The fine aggregates would fill the hot oil bath tanks or oil and would need fresh oil more often. Additionally, the fine aggregates are worth more as an asphalt coated product than an uncoated product.

  • An oil-based solution acts as an environmental seal to the asphalt or asphalt components. As the asphalt is submerged in the oil-based solution, the asphalt binder is protected from degradation, burning and contamination. Current methods merely increase the asphalt temperature until the asphalt binder degrades because of the elevated temperature (and not by the dissolving into an oil based solution). This elevated temperature tends to burn the asphalt binder to a degree that it is unusable or it merely degrades it so that there is no possibility of the asphalt binder performing as would a virgin asphalt mixture.
  • the asphalt binder phase changes from solid to liquid and quickly dilutes, mixes or integrates with the oil-based solution.

  • Other potential oil-based solutions and/or mixtures thereof may also include; virgin, recycled or used motor oil, cutting fluids, greases, waxes, and many others oil based products. Each oil-based solution has a "flash point" or level of volatility and could ignite or explode.

  • the coarse aggregate coated with residual asphalt binder and oil based solution may be cleaned. An added solvent cleaning operation can be applied to the coarse aggregate to remove the residual oil solution and asphalt binder.
  • This coarse aggregate can then be reused in a virgin asphalt mixture and used to produce asphalt that is equivalent to or superior to a virgin asphalt mixture because the reclaimed coarse aggregate has a pre-coated film of asphalt binder mixture thereof and binds better than virgin coarse aggregate.
  • the virgin coarse aggregate is pre-coated with asphalt binder, and is thus a novel asphalt mixture is made that is superior to current mixtures using virgin materials. The pre-coating of the aggregate allows the asphalt binders to develop stronger bonds than the uncoated aggregate.
  • the coarse aggregate coated with residual asphalt binder and oil based solution may be cleaned by merely spinning off excess residual asphalt binder and oil based solution (at an elevated or ambient temperature, because this solution remains in a liquid state at elevated and ambient temperatures).

Abstract

La présente invention concerne un pétrole brut hybride et des procédés de fabrication de celui-ci au moyen de produits de flux de déchets à base de pétrole artificiels ou naturels. Le pétrole brut hybride est composé d'une solution à base de pétrole et de revêtements à base de pétrole qui ont été extraits d'un matériau contenant du pétrole. Ce pétrole brut hybride est créé par élévation de la température de la solution à base de pétrole à ou au-dessus d'une température élevée, à savoir la température de fusion ou de changement de phase du revêtement à base de pétrole de sorte que celui-ci peut devenir liquéfié et se dissoudre dans la solution à base de pétrole et créer le pétrole brut hybride. Le matériau contenant du pétrole est immergé dans la solution à base de pétrole chauffée pour amener les revêtements à base de pétrole à se dissoudre dans la solution à base de pétrole chauffée à la température élevée. La solution à base de pétrole liquide à la température élevée crée un joint d'étanchéité environnemental sur les revêtements à base de pétrole pour les protéger contre la combustion, la carburation ou la dégradation, jusqu'à ce que la solution à base de pétrole liquide soit capable de fournir l'énergie thermique nécessaire pour le changement de phase du revêtement à base de pétrole d'un état solide à un état liquide. À ce stade, les revêtements à base de pétrole changent de phase en toute sécurité dans un liquide et se dissolvent dans la solution à base de pétrole, de façon à créer ainsi le pétrole brut hybride.
