Kerosene, density

The products could be classified as a function of various criteria physical properties (in particular, volatility), the way they are created (primary distillation or conversion). Nevertheless, the classification most relevant to this discussion is linked to the end product use LPG, premium gasoline, kerosene and diesel oil, medium and heavy fuels, specialty products like solvents, lubricants, and asphalts. Indeed, the product specifications are generally related to the end use. Traditionally, they have to do with specific properties octane number for premium gasoline, cetane number for diesel oil as well as overall physical properties such as density, distillation curves and viscosity. [Pg.483]

Other Fiber Evaluation Methods. The extent of fiber separation (fiber openness) is an important evaluation criteria that is commonly measured by several techniques, namely ak permeabiUty, adsorbed gas volume, bulk density, and residence (compression and recovery). The adsorption and retention of kerosene is also used as a measure of fiber openness and fiber adsorption capacity (34). [Pg.353]

Liquid fuels for ground-based gas turbines are best defined today by ASTM Specification D2880. Table 4 Hsts the detailed requirements for five grades which cover the volatility range from naphtha to residual fuel. The grades differ primarily in basic properties related to volatility eg, distillation, flash point, and density of No. 1 GT and No. 2 GT fuels correspond to similar properties of kerosene and diesel fuel respectively. These properties are not limited for No. 0 GT fuel, which allows naphthas and wide-cut distillates. For heavier fuels. No. 3 GT and No. 4 GT, the properties that must be limited are viscosity and trace metals. [Pg.409]

Bulk density is easily measured from the volume occupied by the bulk solid and is a strong func tion of sample preparation. True density is measured by standard techniques using liquid or gas picnometry Apparent (agglomerate) density is difficult to measure directly. Hink-ley et al. [Int. ]. Min. Proc., 41, 53-69 (1994)] describe a method for measuring the apparent density of wet granules by kerosene displacement. Agglomerate density may also be inferred from direcl measurement of true density and porosity using Eq. (20-42). [Pg.1877]

Fuel specifications from different sources may differ in test limits on sulfur, density, etc., but the same general categories are recognized worldwide kerosene-type vaporizing fuel, distillate (or gas ou ) for atomizing burners, and more viscous blends and residuals for commerce and heavy industry. Typical specifications are as follows. [Pg.2362]

Caseade tests are useful in determining all aspeets of seeondary flow. For better visualization, tests have been eondueted in water easeades. The flow patterns are studied by injeeting globules of dibutyl phatalate and kerosene in a mixture equal to the density of water. The mixture is useful in traeing seeondary flow, sinee it does not eoagulate. [Pg.284]

For practical purposes, saturated flow of a single fluid such as gasoline, kerosene, or another particular petroleum product can be predicted by the use of these equations. Standard units of linear measurement (feet, meters, etc.) and discharge are accommodated for by the corrections for viscosity and density. Field-testing procedures can be conducted using standard water well testing procedures. [Pg.160]

Cesiums boihng point is 669.3°C and its density is 1.837 g/cm. Mercury is the only metal with a lower melting point than cesium. It is extremely dangerous when exposed to air, water, and organic compounds or to sulfur, phosphorus, and any other electronegative elements. It must be stored in a glass container containing an inert atmosphere or in kerosene. [Pg.60]

Changes in the chemical composition of the kerosene during volatilization also affect the physical properties of this petroleum product. Table 16.8 summarizes the effect of volatilization on kerosene viscosity, surface tension, and density when 20%, 40%, and 60% of the initial amount has been removed by the partial transfer of light hydrocarbon fractions to the atmosphere. Only the liquid viscosity is affected, with volatilization having a negligible effect on the density and surface tension of the kerosene. [Pg.355]

These results indicate that the enthalpy associated with air (and also steam) has an effect on the resulting droplet size. A larger droplet size with preheated air than steam reveals that there must be effects other than just the enthalpy associated with steam. Some of the possible factors include viscosity and density differences between the gases, and that water contained in steam may become miscible under these conditions. In this case, the large differences in the boiling points between the two fluids (water and kerosene) may lead to disruptive breakup of the liquid fuel, even at 10 mm, via rapid heat transfer from the flame. [Pg.261]

Colorless fuming liquid corrosive density 2.234 g/mL freezes at -33°C boils at 114.15°C critical temperature 318.75°C critical pressure 37.98 atm critical volume 351 cm /mol soluble in cold water, evolving heat decomposed by hot water soluble in alcohol, benzene, toluene, chloroform, acetone and kerosene... [Pg.938]

Liquid products contain sulfur and nitrogen and must be hydroprocessed to improve quality. Separate hydroprocessing units for upgrading the naphtha, kerosene, and gas oil fractions can be used to optimize the overall process. Refined gas oil or diesel fuel is aromatic in character and contains more cycloparaffins than conventional crude oil. The resulting fuel is low in cetane number, high in density, and typically has very good low-temperature handling properties. [Pg.294]

Cartridges containing only potassium chlorate were transported in safety to the site, where they were dipped for a definite time into kerosene just before use. Miedziankit was also manufactured by soaking potassium chlorate cartridges with kerosene in the explosive factory. Kerosene with an ignition temperature above 30°C was employed, to render the product safe for rail transport. According to T. Urbanski [76] the rate of detonation of Miedziankit is 3000m/sec in an iron pipe at a density of 1.7. [Pg.278]

A chemical is soluble in water but insoluble in kerosene. As a consequence, kerosene may be used to determine its density. The density of kerosene is 0.735 g/ml at 22°C. From the following data (obtained as in Problem 35), compute the density of the sample. [Pg.99]

POTASSIUM. [CAS 7440-09-7]. Chemical element, symbol K, at, no. 19, at. wt. 39.098, periodic table group 1 (alkali metals i, mp 63,3cC, bp 760°C. density 0.86 g/cm3 (20°C). Elemental potassium has a body-centered cubic crystal structure. Potassium is a silver-white metal, can be readily molded, and cut by a knife, oxidizes instantly on exposure to air, and reacts violently with H2O, yielding potassium hydroxide and hydrogen gas, which burns spontaneously in air with a violet flame due to volatilized potassium element, is preserved under kerosene, burns in air at a red heat with a violet flame. Discovered by Davy in 1807. [Pg.1360]

The combustion of a saturated hydrocarbon releases 657 kJ per mole of -CH2- groups and 779 kJ per mole of -CH3 groups in the hydrocarbon. How much energy is released by the combustion of 1.00 L of liquid tetradecane (molecular formula C14H30), a major component of kerosene The density of tetradecane is 0.764 g/mL. [Pg.35]
