Definitions

  • This invention is directed towards the art of converting used motor oil to a useable fuel source.
  • Currently, the market for used motor oil has stymied many recycling and reclamation efforts.
  • the market for used motor oil has largely been geared to limited processing steps which convert the used motor oil into a low quality fuel such as bunker oil (#6 fuel oil) .
  • a limited amount of used motor oil is reclaimed and converted into a recycled motor oil product.
  • Used motor oil retains a high energy potential.
  • hazards and cost associated with collecting, storing, transporting, and general handling of used motor oil has limited the efforts to collect used motor oil for disposal or recycling.
  • the prior art provides limited processing of used motor oil for other petroleum products, there remains a need for improvement within the art of converting used motor oil to a high quality energy source.
  • a process including providing a cracking apparatus, the apparatus comprising a cracking vessel, the vessel in communication with a heating means for heating the used oil, a distillation column in communication with the vessel, and a condenser in communication with the distillation column; supplying the cracking vessel with a source of used motor oil; heating the used motor oil to a cracking temperature; cracking the used motor oil to a mixture of lighter molecular weight compounds; separating the lighter molecular weight compounds into a first mixture of a small fraction of volatile light ends and a second mixture of diesel fuel; collecting the second mixture of diesel fuel.
  • Figure 1 is a flow chart of the process of converting used motor oil into diesel fuel.
  • Figure 2 is a graph of distillation curves of used motor oil.
  • waste oil from internal combustion engines can be cracked under low temperature, low severity conditions to yield a number two grade diesel fuel. This process occurs at much lower temperatures than conventionally held to be possible and permits the continuous flow processing of waste oil to a number two grade diesel fuel without coking or fouling of the cracking apparatus.
  • waste oil collected from gas and diesel internal combustion engines is fed into a cracking unit which also serves as a reboiler. While a variety of designs can be employed, the cracking unit/reboiler presently employed is a direct fired unit which burns diesel fuel and air as the heating means for boiler tubes located within the cracking vessel.
  • Heat from the boiler tubes is used to convectively heat waste oil via heat exchange with the boiler tubes.
  • Attached to the cracking/reboiler unit is an overhead distillation column which may be either a packed column or a plate column, both of which are well known in the art of refining petroleum.
  • the distillation column enables the collection of vaporized lighter molecular weight compounds from the top of the column.
  • the vaporized fraction from the top of the column can be collected in an adjacent condenser.
  • a portion of the condensed vapors are returned to the distillation column and provide reflux for the distillation system.
  • the reflux permits the return of material which is heavier than diesel fuel to the cracking vessel for cracking into lighter materials.
  • the amount of the reflux can be varied according to the type of equipment used, the quality of the initial column separation and variations in the feed stock starting material.
  • the starting hydrocarbon material used motor oil, is characterized by a mixture of parafins, napthenes, aromatics, and olefins.
  • a comparison of an ASTM D-86 distillation curve of a typical waste oil feed stock is provided in conjunction with an ASTM D-1160 distillation curve of the same feed stock run under low pressure and at temperatures too low for cracking to occur.
  • the D-1160 curve has been corrected as described in ASTM D-1160-87 to normal atmospheric pressure and at the indicated temperatures.
  • a comparison of the two curves indicates that above thirty percent distilled, cracking becomes vigorous between 60 and
  • the condensed primary product from the cracking process is characterized by a mixture of light ends, paraffins, napthenes, olefins, and aromatics.
  • These light ends can be vaporized with an electric band heater prior to being collected in the condenser, or, alternatively, the primary product can be reheated and passed through a flash pot or a vapor separator where the more volatile light ends are separated and collected. These separated light ends can then be condensed and used to fuel the heat source for the cracking unit.
  • the removal of the light ends described above yields a diesel fuel product which will meet federal specifications for number two diesel fuel. As indicated in table 1, the diesel product has a sufficiently high flash point, cetane rating, and distillation profile to meet federal standards for #2 diesel fuel.
  • Sample A of Table #1 is a composite of the diesel product collected over a several hour-long run on September 23, 1992.
  • the feed stock of waste oil was collected from a service station in the vicinity of Washington, South Carolina.
  • Sample B is a product sample collected from a run on September 26, 1992. It is from the same feed stock as described in sample A.
  • Sample C is a product sample from a run conducted
  • Sample D is a composite sample of the test run as described in sample C and combined with an additional separate run conducted on September 27, 1992.
  • Sample E is a composite of five different samples withdrawn over the course of a run conducted on November 7, 1992.
  • the feed stock for sample E is a mixture of the feed stock used in sample A combined with a feed stock from a diesel truck fleet which operates in the vicinity of Washington, South Carolina.
  • the diesel fuel product can be hydrotreated.
  • the hydrotreat ent saturates the double bonds of olefins, thereby preventing the discoloration of the product.
  • hydrotreatment has the additional advantage of removing sulfur compounds from the diesel product.
  • hydrotreating is not necessary to meet the specifications for number two diesel fuel, hydrotreating will permit a much wider range of feed stock to be used in the process.
  • Highly uniform feed stock sources such as those from an oil recovery system for fleet vehicles, is ideal for processing.
  • Specialty lube shops and service stations represent a feed stock source of extreme variation in oil types in terms of viscosity, gas/diesel ratings, anti-oxidant content, detergent additives and the presence of synthetic oils.
  • community collection sites for used oil often contained other petroleum products such as greases, gear oils and other types of lubricating oils.
  • Some of these heavier, more diverse feed stocks will include sulfur compounds which are added to prevent metal to metal contact.
  • metal particles which are present in the waste oil.
  • Metal particles and shavings from engine wear are suspended in the waste oil. These particles are typically in the micron and submicron range and represent particles sufficiently small such that they pass through standard oil filters. These metal shavings are believed to promote the efficiency of the cracking process in several ways. The large number of the metal particles vastly increases the surface area of metal to hydrocarbon contact within the cracking vessel. Further, the metal particles are thought to operate as a catalyst for the cracking process.
  • Coke formation a common problem in petroleum cracking, is not occurring on the cracking equipment used in the present process. While coke formation is a poorly understood phenomena, it is believed that the low temperatures employed to crack the waste oil are sufficiently mild such that coking is avoided. It may also be that any coke formation which may be occurring, is being selectively deposited upon the suspended metal particles. If so, then the metal/coke particles are removed as part of a continuous slurry withdrawal process. This slurry can be used directly as a bunker fuel oil source. Alternatively, the slurry sediments, namely metal ash and high molecular weight hydrocarbons, can be further condensed with the liquid portions being returned to the feed stock for reentry into the cracking process. The process permits the operator to choose between these two approaches.
