Description

Technical Field

[0002] In the physical refining process of oil, since many pigments in the oil are heat-sensitive, they will decompose automatically after being stored at high temperature for a period of time. Therefore, a decolorizing tank is used to temporarily store the high-temperature oil to achieve a decolorizing effect, so that the oil has a better color during the physical refining process. In the prior art, a decolorizing tank is usually used for decolorization, and a high temperature method is used to separate the pigments in the molecules. Decolorization can be achieved by high temperature, but it will cause damage to other molecules, resulting in the loss of the original characteristics of the raw materials.

However, in the process of decolorization by heating the tank and using activated carbon, the molecules are destroyed. In addition, the addition of activated carbon requires subsequent separation, which increases the number of steps and makes the operation inconvenient. Utility Model Content
