Factors affecting the decolorization effect of refining oil equipment

Factors affecting the decolorization effect of refining oil equipment include:

1. Amount of Clay:

Clay acts as an adsorbent, and its amount is closely related to its type, properties, and the oil loss. Generally, increasing the amount of adsorbent can improve the decolorization effect, but it also increases the loss of neutral oil. Therefore, when choosing the amount of clay, it is necessary to balance its decolorization effect and oil loss.

2. Decolorization Time and Temperature: 

Time and temperature are key factors affecting the decolorization effect. At higher temperatures, the adsorption equilibrium is reached faster, but excessively high temperatures may cause oil oxidation, which is detrimental to decolorization. Therefore, the optimal decolorization time and temperature should be determined through experiments, considering vacuum conditions, the amount of clay, and the properties of the oil.

3. Operating Pressure:

 Atmospheric pressure decolorization has issues such as high temperature and easy oxidation, so vacuum decolorization is commonly used. Vacuum decolorization can maximize the removal of air on the surface of the adsorbent, maximize its activity, prevent oil oxidation and deterioration, and shorten the decolorization time.

4. Degree of Stirring: 

Decolorization is a heterogeneous physical and chemical reaction. Stirring ensures sufficient contact between the oil and the adsorbent, improving the decolorization effect.
