Specific Gravity ASTM

When simple Hquids like naphtha are cracked, it may be possible to determine the feed components by gas chromatography combined with mass spectrometry (gc/ms) (30). However, when gas oil is cracked, complete analysis of the feed may not be possible. Therefore, some simple definitions are used to characterize the feed. When available, paraffins, olefins, naphthenes, and aromatics (PONA) content serves as a key property. When PONA is not available, the Bureau of Mines Correlation Index (BMCI) is used. Other properties like specific gravity, ASTM distillation, viscosity, refractive index. Conradson Carbon, and Bromine Number are also used to characterize the feed. In recent years even nuclear magnetic resonance spectroscopy has been... 

Other considerations for natural gasoline are copper corrosion (ASTM D130 IP 154, IP 411) and specific gravity (ASTM D1298 IP 160), the latter determination being necessary for measurement and transportation. 

Density or specific gravity (relative density) is used whenever conversions must be made between mass (weight) and volume measurements. This property is often used in combination with other test results to predict oil quality, and several methods are available for measurement of density (or specific gravity). However, the density (specific gravity) (ASTM D1298 IP 160) is probably of... 

The calculation of porosity is derived from the determination of the true specific gravity (ASTM D-167) and is derived from the relationship... 

Prepared coal any coal, regardless of its top size, that has been cleaned manually or mechanically includes coal that has been processed over a picking table or air tables through a breaker, jig, or other device which segregates according to size or density (specific gravity) (ASTM D-4749).

Density (ASTM D-1298, IP 160) is an important property of petroleum products because petroleum and especially petroleum products are usually bought and sold on that basis or, if on a volume basis, then converted to mass basis via density measurements. This property is almost synonymously termed as density, relative density, gravity, and specific gravity, all terms related to each other. Usually a hydrometer, pycnometer, or more modem digital density meter is used for the determination of density or specific gravity (ASTM 2000 Speight, 2001). 

In the preliminary assay of petroleum the method of distillation is often used to give a rough indication of the boiling range of the crude (ASTM D-2892, IP 123). The test is carried out at atmospheric pressure and is stopped at 300°C (572°F) to avoid thermal decomposition. The distillate and the residuum can be further examined by tests such as specific gravity (ASTM D-1298, IP 160), sulfur content (ASTM D-129, IP 61), and viscos-... 

Correlative methods have long been used as a way of dealing with the complexity of various petroleum fractions, including naphtha. Relatively easy to measure physical properties such as density (or specific gravity) (ASTM D-2935 ASTM D-3505, ASTM D-4052) are also required. Viscosity (ASTM D-88, ASTM D-445, ASTM D-2161, IP 71), density (ASTM D-287, ASTM D-891, ASTM D-941, ASTM D-1217, ASTM D-1298, ASTM D-1555, ASTM D-1657, ASTM D-2935, ASTM D-4052, ASTM D-5002, IP 160,... 

The product had a softening range of 80°-105°C, a specific gravity (ASTM D792-50) of 1.267 at 25°C, and an iodine number of 55. It is soluble in ketones, benzene, ethyl acetate. When cured in the presence of 2% tert-butyl perbenzoate (15 min at 175°C under 6000 p.s.i. of pressure), a thermset resin is formed with a Rockwell hardness of 114-116 (M-scale), flexural strength of 9000 p.s.i., and a heat distortion point at 264p.s.i. of 155°C [103]. 

Bulking value n. Reciprocal of apparent density. Solid volume of a unit weight of material, usually expressed as gallons per pound or 1/kg. For practical purposes this is 0.120 divided by the specific gravity (ASTM). Syn specific volume.
