A measure of resistance of the fuel to flow at a stated temperature. Kerosene, also known as paraffin, is a combustible hydrocarbon liquid which is derived from petroleum. Given all of these variables and details, several organizations decided to come up with a way to characterize lubricating oils so that members of their respective organizations would have a uniform and simple way to communicate, educate and ultimately protect their interests. This is because all oils thin when heated, so to get the right film thickness at operating temperatures oil manufacturers needed to start with a thick oil. It changes with temperature, shear rate, pressure, and thickness. These types of lamps are still in use today in areas of the world without electricity, because they give a much better light than a simple wick-type lamp does. The necessary equipment was sold under the trademark "Econom". It is widely used as a fuel in aviation as well as households. If the skier was skiing on a lake of SAE 90/ISO 220 gear oil and all of the other conditions were exactly the same, then the amount of spray generated would be considerably less because the fluid would resist the force of the ski to a much greater degree. In the United Kingdom, manufacturing oil from coal (or oil shale) continued into the early 20th century, although increasingly overshadowed by petroleum oils. Kerosene type fuels have lower energy content than diesel fuels and therefore will We don’t have to. [46], Kerosene is sometimes used as an additive in diesel fuel to prevent gelling or waxing in cold temperatures. BS 2869 Class C2 is a heavier distillate, which is used as domestic heating oil. If the machine runs very fast then the machine designer will specify a lubricant that can get out of the way, and back into the way just as quickly. How does motor oil viscosity work? It is obtained from petroleum and used for burning in kerosene lamps and domestic heaters or furnaces, as a fuel or fuel component for jet engines, and as a solvent for greases and insecticides. [40], In countries such as India and Nigeria, kerosene is the main fuel used for cooking, especially by the poor, and kerosene stoves have replaced traditional wood-based cooking appliances. In the early to mid-20th century, kerosene or tractor vaporising oil (TVO) was used as a cheap fuel for tractors and hit 'n miss engines The engine would start on gasoline, then switch over to kerosene once the engine warmed up. That a product has an ISO VG number associated with it has no bearing on its performance characteristics. Mass is a measure of how 'heavy' an object is. A higher oil viscosity number indicates a thicker oil. For petroleum-based liquids, this covers approximately the range from kerosene to cylinder oils. In the United Kingdom, two grades of heating oil are defined. hbspt.cta.load(3951034, 'c99217f3-09e7-4751-bc3a-7739dac44a0e', {}); Viscosity Index: What It Is and Why It's Important. [13] The freeze point of kerosene depends on grade, with commercial aviation fuel standardized at −47 °C (−53 °F). Most of these uses of kerosene created thick black smoke because of the low temperature of combustion. More ubiquitous in the late 19th and early 20th centuries, kerosene space heaters were often built into kitchen ranges, and kept many farm and fishing families warm and dry through the winter. At one time, citrus growers used a smudge pot fueled by kerosene to create a pall of thick smoke over a grove in an effort to prevent freezing temperatures from damaging crops. [33], The fuel, also known as heating oil in the UK and Ireland, remains widely used in kerosene lamps and lanterns in the developing world. Dynamic vs. Kinematic Viscosity: What's the Difference? It is sometimes used as a heat source during power failures. Kerosene can be applied topically to hard-to-remove mucilage or adhesive left by stickers on a glass surface (such as in show windows of stores). You will see oil viscosity measurement in lube articles stated in kinematic (kv) and absolute (cSt) terms. For lubricating oils, viscometers tend to operate by gravity rather than pressure. Kerosene is used as a fuel in portable stoves, especially in Primus stoves invented in 1892. [46] For the five 6.4 meganewton sea-level thrust F-1 rocket engines of the Saturn V, burning together, the reaction generated roughly 1.62 × 1011 watts (J/s) (162 gigawatt) or 217 million horsepower. A kerosene stream of Dubai crude has a kinematic viscosity of 1.12 cst at 323 K and a viscosity of 0.70 cst at 371.9 K. Determine the kinematic viscosity of the … In the metric system, the unit of kinematic viscosity is the square centimeter per second or the stoke. Conversely, the aforementioned AW-68 hydraulic oil has an ISO VG rating of 68 this, in turn, allows it to be classified as a single-grade lubricant, or straight-grade oil. This measurement is related to how an oil flows when it is cold, such as at engine start-up. There are SAE (Society of Automotive Engineers) grades for gear oils and crankcases (engines), AGMA (American Gear Manufacturers Association) grades for gear oils, SUS (Saybolt Universal Seconds), cSt (kinematic viscosity in centistokes), and absolute viscosity. 1-K grade kerosene burns cleaner with fewer deposits, fewer toxins, and less frequent maintenance than 2-K grade kerosene, and is the preferred grade of kerosene for indoor kerosene heaters and stoves. Kerosene viscosity is dependent upon temperature. JP-8, (for "Jet Propellant 8") a kerosene-based fuel, is used by the United States military as a replacement in diesel fueled vehicles and for powering aircraft. Kerosene vapor diffused in air (as from a lamp wick) will burn at a maximum flame temperature of 990 °C (1814 °F). [41] In Nigeria an attempt by the government to remove a fuel subsidy that includes kerosene met with strong opposition.[42]. Overcoming the Risks of Cold Machine Starts, Unboxing: Luneta Column Sight Glass in Tritan™, Unboxing: Mystik® JT-9™ LeakShield® AW Hydraulic Oil, Product Unboxing: Hy-Pro Compact Offline Filter, The Cost Effective Benefits of a High Performance Kidney Loop System, 8 Steps to Successfully Implement a Preventive Maintenance Program. 1 Typical Liquids SSU Stokes Centistokes Poises* Centipoises Engler Seconds at 65°F 27.7 0.006 0.600 0.005 0.480 NA 27.99 Gasoline Water goes through in one second. [26] He has been dubbed the Grandfather of the American Oil Industry by historians. Ethanol was sometimes used instead, but the flames it produces look less impressive, and its lower flash point poses a high risk. Common Liquid Types Viscosity Low Viscosity High; Water @ 70° F: 1: 5: Blood or Kerosene: 10: 10: Anti-Freeze or Ethylene Glycol: 15: 15: Motor Oil SAE 10 or Corn Syrup Further, there is no intention to offer quality definition of lubricants with this scale. In practice, kerosene has a lighter viscosity value and this *does* make it burner at a hotter temperature in an engine. This would reflect an order of (center point) uncertainty in calculations similar to that imposed by dimensional manufacturing tolerances. In Europe following the Second World War, automobiles were similarly modified to run on kerosene rather than gasoline, which they would have to import and pay heavy taxes on. Using a pattern that used a small, easily manageable number of viscosity grades. In the United Kingdom and Ireland, kerosene is often used as a heating fuel in areas not connected to a gas pipeline network. While it is true that some viscosity grades will be left out of the mix as companies move toward adopting the ISO designation, it is not necessary that the users of those products have to move away from them. The first number ends with the letter 'W', which stands for Winter. "Salamanders" are kerosene space heaters used on construction sites to dry out building materials and to warm workers. [30] Because Gesner's original Kerosene had been also known as "coal oil," generic kerosene from petroleum was commonly called "coal oil" in some parts of the United States well into the 20th century. [23][24] Gesner's method of purifying the distillation products appears to have been superior to Young's, resulting in a cleaner and better-smelling fuel. Through the years, lubricant users have been treated to a number of ways to designate viscosity grades of the lubricants used in manufacturing. [11], Regardless of crude oil source or processing history, kerosene's major components are branched and straight chain alkanes and naphthenes (cycloalkanes), which normally account for at least 70% by volume. Between 1980 and 1984, 3,756 Saab 99 Petros and 2,385 Talbot Horizons (a version of the Chrysler Horizon that integrated many Saab components) were made. United States Bureau of the Census, 1960, Historical Statistics of the United States, Colonial Times to 1957, p.445. This is called centistokes, which we have already noted. A table of common liquids grouped by class or type including information on the viscosity at a given temperature and whether the liquid is Newtonian or Thixotropic This covers nearly every type of application that the lubricant practitioner can expect to encounter. Like specific gravity, viscosity can be altered by a change in temperature, but unlike specific gravity it can also be altered by agitation. Kerosene was also produced during the same period from oil shale and bitumen by heating the rock to extract the oil, which was then distilled. [10], The ASTM International standard specification D-3699-78 recognizes two grades of kerosene: grades 1-K (less than 0.04% sulfur by weight) and 2-K (0.3% sulfur by weight). Multiple substances are directly toxic to the lungs or stimulate an inflammatory response when aspirated; gastric acid is the most common such aspirated substance, but others include petroleum products (particularly of low viscosity, such as petroleum jelly) and laxative oils … For example, an abnormally low flash point on a sample of kerosene can indicate gasoline contamination. It has seen use in mosquito control in Australia. There are two numbers that define the viscosity of an oil. In outdoor activities and mountaineering, a decisive advantage of pressurized kerosene stoves over gas cartridge stoves is their particularly high thermal output and their ability to operate at very low temperature in winter or at high altitude. The really important thing to keep in mind is that there is no correlation between viscosity and specific gravity. Manufacture of kerosene under the Gesner patents began in New York in 1854 and later in Boston—being distilled from bituminous coal and oil shale. 1. The American whaling fleet, which had been steadily growing for 50 years, reached its all-time peak of 199 ships in 1858. Oil viscosity is the parameter that plays an important role in lubrication. The measure of the fluid’s viscosity is the measure of the amount of time that it takes for the designated amount of oil to flow through the tube under very specific conditions. This makes the color of the crystal become dull. In X-ray crystallography, kerosene can be used to store crystals. For petroleum-based liquids, this covers approximately the range from kerosene to cylinder oils. These patents were subsequently upheld in both countries in a series of lawsuits, and other producers were obliged to pay him royalties. Kerosene can be mixed with diesel fuel to gain a couple of benefits. [27] Since the 1840s, Kier's salt wells were becoming fouled with petroleum. On a side note, if you are using in-service oils, it is probably worth measuring the viscosity in absolute units. Each viscosity grade is designated by the nearest whole number to its midpoint kinematic viscosity in mm2/s at 40ºC (104ºF), and a range of +/- 10 percent of this value is permitted. This property is called absolute viscosity (also known as dynamic viscosity) and is measured in centipoises (cP). Young took out a patent on his process and the resulting products in 1850, and built the first truly commercial oil-works in the world at Bathgate in 1851, using oil extracted from locally mined torbanite, shale, and bituminous coal. They formed the North American Gas Light Company, to which he assigned his patents. Different approaches were thoroughly considered before the ISO Technical Committee (TC23) settled on an approach that is logical and easy to use. The two are related through the specific gravity of the fluid. Before the days of electrically lighted road barriers, highway construction zones were marked at night by kerosene fired, pot-bellied torches. It can be also used to prevent air from re-dissolving in a boiled liquid,[49] and to store alkali metals such as potassium, sodium, and rubidium (with the exception of lithium, which is less dense than kerosene, causing it to float).[50]. The project, codenamed "Project Lapponia", was headed by Simo Vuorio, and towards the end of the 1970s, a working prototype was produced based on the Saab 99 GL. On the night of 31 July 1853, doctors at the local hospital needed to perform an emergency operation, virtually impossible by candlelight. It should also relate closely to other selected temperatures used to define properties such as viscosity index (VI), which can aid in defining a lubricant. [5] World total kerosene consumption for all purposes is equivalent to about 1.2 million barrels (50 million U.S. gallons; 42 million imperial gallons; 190 million liters) per day. Assuming a room temperature is 20 degrees Celsius (68 Fahrenheit) the kinematic viscosity of kerosene would then be 2.17 centistokes (35 SSU). Air-blown asphalts typically use a softening point test. Paraffin wax is a waxy solid extracted from petroleum. Kerosene is generally not recommended as fuel for indoor fire dancing, as it produces an unpleasant (to some) odor, which becomes poisonous in sufficient concentration. Water has a viscosity measured in centistokes of 1. [18], Although "coal oil" was well known by industrial chemists at least as early as the 1700s as a byproduct of making coal gas and coal tar, it burned with a smoky flame that prevented its use for indoor illumination. The viscosity of the gas saturated oil is found as a function of dead oil viscosity and solution gas-oil ratio (GOR). Thick liquids are said to have a high viscosity and thin liquids a low viscosity. The flash point of kerosene is between 37 and 65 °C (100 and 150 °F), and its autoignition temperature is 220 °C (428 °F). Density is a measure of how 'heavy' a material is. Bitumen is a common binder used in road construction. There, he secured backing from a group of businessmen. However, kerosene remained the predominant commercial end-use for petroleum refined in the United States until 1909, when it was exceeded by motor fuels. [32], In 2013, kerosene made up about 0.1 percent by volume of petroleum refinery output in the United States. The measure in centistokes can be misleading because the specific gravity of lubricants changes with age, generally moving up. When a hydrated crystal is left in air, dehydration may occur slowly. One is the measure of how the fluid behaves under pressure, such as a pressurized hydraulic line. As a petroleum product miscible with many industrial liquids, kerosene can be used as both a solvent, able to remove other petroleum products, such as chain grease, and as a lubricant, with less risk of combustion when compared to using gasoline. Kerosene was a significant fire risk; in 1880, nearly two of every five New York City fires were caused by defective kerosene lamps.[37]. Adequate viscosity, particularly with kerosene type fuels is a major concern. Oil viscosity is graded by measuring the time it takes for a standard amount of oil to flow. The 20 viscosity grades with the limits appropriate to each are listed in Table 1. The process of distilling crude oil/petroleum into kerosene, as well as other hydrocarbon compounds, was first written about in the 9th century by the Persian scholar Rāzi (or Rhazes). [21], In 1851, Samuel Martin Kier began selling lamp oil to local miners, under the name "Carbon Oil". The petroleum discovery at the Drake Well in western Pennsylvania in 1859 caused a great deal of public excitement and investment drilling in new wells, not only in Pennsylvania, but also in Canada, where petroleum had been discovered at Oil Springs, Ontario in 1858, and southern Poland, where Ignacy Łukasiewicz had been distilling lamp oil from petroleum seeps since 1852. [55], Gesner, Abraham, "Improvement in kerosene burning-fluids," U.S. Patent no.s, (Excerpt from Yo-Ho-Ho and a Bottle of Unrefined Complex Liquid Hydrocarbons). We can see how much water a professional skier displaces when he runs through a ski course. To the new entrant into the lubrication field, the number of options can be confusing, particularly if the primary lubricant supplier does not associate one of the prominent viscosity systems to the product label. When the seep became exhausted, he experimented with the dry distillation of coal, especially the resinous "boghead coal" (torbanite). Kerosene is widely used in Japan as a home heating fuel for portable and installed kerosene heaters. At first, Kier simply dumped the useless oil into the nearby Pennsylvania Main Line Canal, but later he began experimenting with several distillates of the crude oil, along with a chemist from eastern Pennsylvania. Łukasiewicz realized the potential of his work and quit the pharmacy to find a business partner, and then travelled to Vienna to register his technique with the government. As such, increase in the price of kerosene can have a major political and environmental consequence. [25], In 1848, Scottish chemist James Young experimented with oil discovered seeping in a coal mine as a source of lubricating oil and illuminating fuel. a typical engine oil was a SAE 30. He distilled this by a process of his own invention from crude oil. National and international standards define the properties of several grades of kerosene used for jet fuel. It is principally obtained as a residual product in petroleum refineries after higher fractions like gas, petrol, kerosene and diesel, etc. SPECIFICATION FOR KEROSENE Kerosene meets BS 2869 : Part 2 : 1998 Classification C2 Fuel Parameters British Standard Typicals Specification Parameters Max Kinematic Viscosity (cSt at 40°C) 1.0 min\ 2.00 max 2.0 Density at 15°C 9 (kg / litre) 0.820 0.804 Flash Point (°C) Closed Abel 38 … Petroleum Refining and Fractional Distillation A study of possible temperatures indicated that 40ºC (104ºF) was suitable for the industrial-lubricant classification as well as for the lubricant-definition properties mentioned above. [16] During the Chinese Ming Dynasty, the Chinese made use of kerosene through extracting and purifying petroleum and then converted it into lamp fuel. In the winter time, kerosene is extremely useful for changing the cold weather handling temperatures of diesel fuel. [9] It is miscible in petroleum solvents but immiscible in water. Additives such as RangeKlene can be put into kerosene to ensure that it burns cleaner and produces less soot when used in range cookers.[39]. According to ISO, the kinematic viscosity of heavy fuels should be specified in centistokes (cSt = 10-6 m 2 /s) at 100°C. If a machine is heavily loaded then the machine designer will use a lubricant that resists being pushed around, which would be heavy like honey. Read on to have oil viscosity explained in simple terms. In 1852, he took out a United States patent for the same invention. These fuel grade kerosenes meet specifications for smoke points and freeze points. [22] In 1854, Gesner moved to Newtown Creek, Long Island, New York. Table 2 pulls together some popular viscosity measurement methods into one table. Viscosity arising due to internal molecular friction produces the frictional drag effect. It can also be used as a cooling agent in metal production and treatment (oxygen-free conditions).[51]. The original viscosity grades were all mono-grades, e.g. On some engines a heat valve on the manifold would route the exhaust gases around the intake pipe, heating the kerosene to the point where it was vaporized and could be ignited by an electric spark. It is used less for cooking, with LPG being preferred because it is easier to light. Today, kerosene is mainly used in fuel for jet engines in several grades. The rise of the gasoline-powered automobile in the early 20th century created a demand for the lighter hydrocarbon fractions, and refiners invented methods to increase the output of gasoline, while decreasing the output of kerosene. To simplify, the oil’s viscosity represents the measure for which the oil wants to stay put when pushed (sheared) by moving mechanical components. Kerosene is sometimes recommended as a folk remedy for killing head lice, but health agencies warn against this as it can cause burns and serious illness. It is possible to find yourself exceeding an absolute viscosity limit for a machine but still have a kinematic measure that indicates you are OK. Kerosene, flammable hydrocarbon liquid commonly used as a fuel. Fuel viscosity . By 1860, just two years later, the fleet had dropped to 167 ships. Many people knew of his work, but paid little attention to it. The distillation process was repeated until most of the volatile hydrocarbon fractions had been removed and the final product was perfectly clear and safe to burn. The combustion reaction can be approximated as follows, with the molecular formula C12H26 (dodecane): 2 C12H26(l) + 37 O2(g) → 24 CO2(g) + 26 H2O(g); ∆H˚ = -7513 kJ, In the initial phase of liftoff, the Saturn V launch vehicle was powered by the reaction of liquid oxygen with RP-1. In addition, some of the heavier hydrocarbons that previously went into kerosene were incorporated into diesel fuel. The fluid gets thicker at lower temperatures and it gets thinner at higher temperatures. [17] The Chinese made use of petroleum for lighting lamps and heating homes as early as 1500 BC. To add to the confusion, two measures of temperature (Fahrenheit and Celsius) can be applied to most of these, not to mention that viscosity might be presented at either 40°C (104°F) or 100°C (212°F). This is similar to the amount of time it takes a specific volume of fluid at a specific temperature to drain through a funnel. One method used clay as an absorbent, whereas the other method used ammonium chloride (sal ammoniac).
