Turbidity change of oil product transparency after filtrating from waste liquid

The transparency of oil products is to observe the transparency of oil quality with naked eyes. The main factors affecting the transparency of oil products are external and intrinsic two aspects. Under the conditions of transportation, storage and operation, oil is easily polluted by the environment, such as water, mechanical impurity and free carbon in oil, which will affect the transparency of the oil, which is the influence of external factors. The transparency of oil products, especially in low temperature conditions, will be separated by fog, which will affect the transparency of oil, even the turbidity of oil, because of the dissolving of paraffin and scum in the oil. Therefore, when it is controversial to judge the transparency of oil products under normal temperature, the oil quality can be noted in the oil quality standard in the 100ml measuring cylinder, at the temperature of 20 and 5 C. The oil should be transparent and transparent. If there is a dispute, the content of the mechanical impurities in the oil should be measured by GB511-77. The meaning is that at the temperature of 20 and 5 degrees Celsius, there should be no separation of free paraffin and dregs in oil. The quality of oil should be clear and transparent. If the oil is still opaque at the temperature of 20 and 5 C, and the content of the mechanical impurity in the oil is not at the same time, it shows that the content of the paraffin and scum in the oil is not qualified, and the transparency of the oil can not be met.
Observing the color and transparency of oil products is of significance to production operation. The new hydraulic oil and turbine oil are usually yellowish. The lighter the color of the oil, the better the degree of refinement and stability. If the oil refining is not good, there will be some unstable compounds such as resin pitch and so on, which will deepen the oil color. Therefore, the color of oil can be used to judge the degree of removing bitumen, resin and other dyed substances in the oil, that is to judge the refining degree of the oil and the oil in the process of transportation and storage. The tanks and oil tanks should be checked strictly to ensure the cleaning. Otherwise, the oil with good color will be polluted because of the uncleanness of the container. It will also cause the oil color to deepen and the quality to deteriorate. The main component of the mineral oil is hydrocarbon, which is influenced by the operating conditions such as temperature, air, corona, electric arc and electric field during operation, and the oil should be gradually oxidized. One of the main manifestations of oil oxidation (or aging) is that the color of oil gradually deepens. This is because the oil itself oxidize, in addition to the formation of acid substances, but also produce a certain amount of gum, asphaltene and other substances that will deepen the color of oil. For example, the variation of the color of insulating oil is usually caused by the production of carbon in the oil. Therefore, observing the rapid change of oil in operation is a manifestation of deterioration of oil quality or internal failure of equipment. The transparency of the observed oil will affect the transparency of the oil except for the presence of moisture and mechanical impurities in the oil. It is also necessary to observe whether there are paraffin and slag in the oil under certain temperature, oil and environmental conditions, that is, to check the refining degree of oil products in this respect, and whether to meet the requirements.
