Definitions

  • the present invention relates, generally, to apparatuses for removing contaminants, such as water and gasoline, from oil, and, more particularly, to apparatuses which remove liquids having low vapor pressures from oil utilizing the process of distillation. More specifically, the invention relates to single-chamber, single-channel distillation apparatuses.
  • distillation-type liquid separations and reclamation devises for evaporation/separation and removal of volatile contaminants from contaminated liquid.
  • Most of these units are promoted for the purpose of purifying lubricating oil in combustion engines, and utilize what is call the thin-film distillation process, wherein the oil is passed over a heated flat horizontal surface (distillation plate).
  • the theory is that as oil flows over a flat, heated, nearly-horizontal surface, it spreads out as a "thin film,” thereby enabling more volatile contaminants, such as water or gasoline molecules, to escape from the film. Removal of the volatile contaminants is followed by a subsequent collection of the "purified" oil.
  • distillation/separation units of this type are shown in U.S. Patent Nos. 2,839,196; 3,756,412; 4,115,201; 4,189,351; 4,146,475; 4,289,583; 4,443,334; 4,349,438; 4,354,946; 4,369,110; 4,717,474; 4,943,352; 4,830,745; 5,242,034, 5,322,596; 5,630,956; and 5,630,912.
  • a serious problem associated with the distillation units which incorporate an electric heating element is that a potentially explosive environment is created in the distillation chamber.
  • Another problem associated with most of the prior-art distillation units is that calibration of the oil flow through the distillation unit is a complicated and time consuming process.
  • Another problem with the prior art units is that the entrance into the distillation chamber is prone to clogging. In the entrance become partially or completely clogged, oil flow through the device will be reduced. Reduced oil flow will result in increased chamber temperatures, which may cause oil within the distillation chamber to overheat, carbonize, or even burn.
  • Patents Nos. 5,824211 and 5,776,315 disclose evaporative distillation units that do not require separate heating elements in order to maintain the temperature of the liquid at the contaminant vaporization temperature. Rather, vaporization heat is provided by the liquid itself.
  • Most internal combustion engines have a thermostat-controlled operating temperature of about 115°C.
  • the most common fuels utilized in internal combustion engines are compressed natural gas (i.e., methane), liquid propane, gasoline, kerosene and diesel fuel.
  • Diesel aircraft engines are typically designed to run on kerosene, which is also known as jet fuel. Methane boils at -161.5°C, and propane boils at 42.1°C.
  • Kerosene is obtained from the fractional distillation of petroleum between 150°C and 275°C, while diesel fuel is produced from the fractional distillation of petroleum between 200°C and 350°C.
  • gasoline is quite variable, the bulk of typical gasoline consists of hydrocarbons with between 4 and 12 carbon atoms per molecule (generally known as C4 - C12 molecules) having fractional boiling points between 40°C and 200°C.
  • C4 - C12 molecules carbon atoms per molecule
  • an evaporative distillation unit is limited to removing liquids having boiling points less than about 110°C. That includes methane, propane, water, and the molecules comprising gasoline which have boiling points between 40°C and about 110°C.
  • Water is a far more insidious contaminant than solid particles, and is often overlooked as the primary cause of component failure.
  • Water can exist in oil in three states. The first state is an oil-water solution, which is characterized by individual water molecules dispersed throughout the oil. Oil can contain a significant concentration of dissolved water with no visible indication of its presence. Most industrial oils such as hydraulic fluids, turbine oils, etc., can hold as much as 200 to 600 ppm of water (0.02 to 0.06 percent) in the dissolved state depending on the temperature and age of the oil.
  • Aged oils can hold three to four times more water in the dissolved state than new oil.
  • the second state is an oil-water emulsion. In this state, the amount of water in the oil has exceeded the maximum solubility level for the particular oil. After exceeding the saturation level, the excess water is suspended in the oil in microscopic droplets. This is similar to the formation of fog when the ambient temperature drops below the dew point. Just as fog obscures visibility, the suspension of water droplets in oil gives the oil a cloudy or hazy appearance.
  • the third state is the presence of free water. As additional water is added to an oil-water emulsion, at some point a separation of the two phases will result in a layer of free water, as well as a layer of free and/or emulsified oil. For mineral oils and polyolefin synthetics whose specific gravity is less than 1.0, this free water layer is found on the bottom of tanks and sumps.
  • journal bearings for example, the incompressibility of water relative to oil can result in a loss of the hydrodynamic oil film, which, in turn, leads to excessive wear. As little as one percent water in oil can reduce the life expectancy of a journal bearing by as much as 90 percent. Roller and ball bearing assemblies fare even worse. Not only will water destroy the oil film strength, but both free and emulsified water under the extreme temperatures and pressures generated in the load zone of a rolling element bearing can result in instantaneous flash-vaporization causing erosive wear to occur.
  • water molecules can disassociate into their constituent oxygen and hydrogen atoms as a result of the high pressures generated in the load zone of a rolling element bearing. Due to their relatively small size, the hydrogen ions produced by this process can absorb onto the surface of the bearing raceway, causing a change in subsurface bearing metallurgy.
  • the result of this metallurgical change is a phenomenon known as hydrogen embrittlement, which causes the bearing raceway material to become weak or brittle and prone to cracking beneath the surface. When these subsurface cracks spread to the surface, the result can lead to pitting and spalling.
  • water has a direct harmful affect on machine components, but it also plays a direct role in the aging rate of lubricating oils.
  • the presence of water in a lubricating oil can cause the progress of oxidation to increase tenfold, resulting in premature aging of the oil, particularly in the presence of catalytic metals such as copper, lead and tin.
  • certain types of synthetic oils such as phosphate esters and dibasic esters are known to react with water, resulting in the destruction of the base stock and the formation of acids. It is not just the base oil that can be affected by moisture contamination.
  • Certain additives such as sulfurous AW and EP type additives and phenolic antioxidants are readily hydrolyzed by water, resulting in both additive mortality and the formation of acidic by-products. These acidic by-products can then cause corrosive wear, particularly in components containing soft metals such as babbitt used with journal bearings and bronze and brass components.
  • Other additives such as demulsifying agents, dispersants, detergents and rust inhibitors can be washed away by excessive moisture. This results in sludge and sediment buildup, filter plugging and lessened resistance to emulsification.
  • the most precise method for determining the amount of free, emulsified and dissolved water in a lubricating oil is the Karl Fischer moisture test.
  • the Karl Fischer test is capable of quantifying water levels as low as 10 ppm or 0.001 percent and should be the method of choice when highly-accurate water concentrations need to be ascertained.
  • the primary contaminant intended for removal is water, in the form of vapor, other volatile components that have a boiling point less than the temperature of the incoming oil can also be removed.
  • the oil inlet is easily removable from the distillation device for cleaning and/or unclogging.
  • the bypass nature of the device protects the engine or machine from damage in the unlikely event that the device becomes clogged.
  • An additional goal of the present invention is to provide a contaminant distillation device that is highly resistant to through-flow clogging.
  • a purification device that removes volatile contaminants from a pressurized flow of oil utilizing a distillation process preferably sustained by heat from the oil, itself.
  • the device may also be used successfully to purify contaminated transmission fluid, liquid-hydraulic fluid, machining oil, cooking oil, heating/cooling fluid, and many other types of oils. Heating of the fluid is necessary only if the impurities to be removed boil at a temperature that is greater than the temperature of the fluid when the purification process occurs.
  • the fluid may be pumped directly into the distillation chamber for distillation, separation, and removal of volatile contaminants therefrom, after which the processed fluid is returned to the sump or other container from which it is used.
  • the purification device comprises a generally enclosed distillation chamber having a series of descending steps therein.
  • the device operates in a bypass mode, with contaminated engine lubricating oil being diverted from an engine oil galley, where oil is under pressure from pumping action of the engine oil pump, to the distillation chamber. Oil enters the chamber through an orifice that is sized to minimize the oil pressure drop of the system. For diesel engines having a displacement of about 7 liters, the optimum orifice size is deemed to be a cylindrical aperture about 0.031 inch, or 0.89 mm. The total amount of oil pumped through such an engine in an hour is about 11,356 liters (roughly 3,000 gallons). Ten gallons per hour are diverted as bypass to the distillation chamber.
  • the stream of hot oil entering the chamber through the orifice is dispersed into a thin film on the uppermost step by either reflecting it off of a wall at the side of the uppermost step or by directing it at a dispersal post, having a curved front surface, that is positioned near the front edge of the upper step.
  • the oil flows as a thin film over each of the downwardly-sloped steps, until it reaches a collection port below the bottom step.
  • the thin film of oil on each step and the churning, tumbling and kneading of the oil as it descends the front of each step enhances the likelihood that low-boiling molecules trapped in the oil will escape the film.
  • thickness of the oil film is reduced still further, thereby providing maximum opportunity for low-boiling molecules to escape the thin film.
  • no filters or heating elements are required.
  • Heat content of the incoming oil which is regulated by the thermostat of the engine, provides sufficient heat within the chamber for molecules having a boiling point below the temperature of the incoming oil to escape as long as normal flow rates are maintained through the volume-regulating orifice. As engine thermostats are typically designed to maintain operating temperature around 240°F, the operating
  • volatile contaminants escape the oil film as the oil makes its way down the steps and over the sharp edges of the steps.
  • Vaporized contaminants escape the distillation chamber through a one-way ball valve and are directed to the intake of the engine.
  • Purified oil within the distillation chamber flows into a drain and is returned to the oil sump of the engine.

Abstract

L'invention porte sur un dispositif de purification d'huile, lequel dispositif retire des contaminants volatils à partir d'un écoulement pressurisé de nombreux types d'huile utilisant un processus de distillation de préférence maintenue par de la chaleur à partir de l'huile elle-même. Le dispositif comprend une chambre de distillation globalement close ayant une série d'étages descendants à bords aigus. Le dispositif fonctionne dans un mode de derivation, une huile de lubrification de moteur contaminée étant dérivée à partir d'un compartiment d'huile sous pression à l'intérieur du moteur jusqu'à la chambre de distillation. Le courant d'huile chaude entrant dans la chambre par l'intermédiaire d'un orifice de restriction d'écoulement est dispersé en un film mince sur l'étage le plus haut soit par réflexion de celui-ci à partir d'une paroi sur un côté de l'étage le plus haut soit par direction de celui-ci au niveau d'un montant de dispersion ayant une surface avant incurvée. De l'huile purifiée revient vers la cuve d'huile du moteur par l'intermédiaire d'un orifice de drain au-dessous de l'étage le plus bas. Des contaminants volatils sont amenés à s'échapper au sommet de la chambre de distillation.
