Study Notes
Swoia Fisical Propertis blong Nefta and Nefta Pradak
- Understanding physical and chemical properties of oils, oil fractions, and gases is important for controlling oil processing and using oil products.
- Knowing the physical properties of oil products is necessary for quality control and their use in various industries
- Oil products are complex mixtures of hydrocarbons with impurities of sulfur, nitrogen, oxygen-containing compounds and other substances, so their quality is evaluated via combination of physical and chemical indicators.
-
Essential indicators for characterizing oil products:
- Density
- Molar mass
- Vapor pressure
- Viscosity
- Viscosity index
- Fractional composition
- Freezing point
- Crystallization temperature
- Flash point
- Ignition temperature
- Self-ignition temperature and others.
Density
- Density is one of the main indicators of the quality of oils and oil products.
- Density is important for calculating the mass of the oil products based on its volume.
- Density helps in providing an estimate about the chemical nature of the oil products.
- Density decreases with increasing temperature.
- There are formulas to calculate how density changes according to temperature.
- There's a standard temperature at which to measure density (usually 20°C or 15.6°C).
