modern requirements that apply to the quality of the oil, are high.Therefore, its production requires constant perfection to meet all petroleum standards and norms.Relevant organizations have control over the production and the final product.
standardization system, which is developed by the state, is the standard to which all manufacturers equal.Compliance with the conditions it is compulsory for all.
oil and other petroleum products - a liquid mixture having a complex composition of hydrocarbon compounds and closely boiling hydrocarbons, and hetero atoms of oxygen, nitrogen, sulfur, some metals and acids.
One of the quality indicators is the density of the oil.This amount quiescent mass in a unit volume.The density of oil and its definition is a prerequisite for an easier calculation of their mass number.This is due to the fact that inclusion of oil in terms of volume is not very convenient, because this figure can vary depending on temperature change.
oil density is measured in kilograms per cubic meter.One can easily determine the mass, volume, and knowing the density indicators.Mass unlike has no volume depending on the temperature of the product.
usually used indicators such as the relative density of petroleum.It is defined as the ratio of mass of oil to the weight of pure water, which is taken in the same amount, with the temperature of + 4 °.Such a temperature level is not chosen by chance.The water in this case has the highest density, which is equal to 1000 kilograms per cubic meter.In order to determine the relative density of the oil, the temperature should be + 20 °.In this case, it may be from 0.7 to 1.07 kilograms per cubic meter.
There are other physical properties of the oil.
Specific gravity - a weight which is one unit of volume.In another way, a force which is attracted to the ground one volume of the substance.That is, the density multiplied by the acceleration due to gravity.
Another concept is the specific gravity.The value of this index is a numerical value, which has a relative density.And we use it for the calculation of this indicator.
Specific gravity and density of the oil can change their values when the temperature changes.Therefore, to calculate the density, found at the same temperature at the same rate at other temperature data, it is necessary to take into account the correction for density changes depending on the temperature change.
oil density calculated in practice, is considered to be an additive quantity.This is due to the fact that the figure can be obtained as an average value for several petroleum products.
for each district oil characterized by their physical properties of the product.For example the density of oil in Tyumen generally varies from 825 to 900 kilograms per cubic meter.
study of the physical properties of the product is necessary not only for its rational use for commercial purposes and for sale on the world market.Sometimes it can be very important in addressing environmental disasters resulting from the release of oil into the environment and helps to avoid many mistakes.
Thus, in case of liquidation of the accident attempting to remove the oil slick using arson, without considering that the physical characteristics of the product have changed as a result of interaction with the environment.Therefore, these factors should be considered in case of cleaning the water surface.This is a very important factor that should not be ignored.
