Appearance of vacuum residue
Thread Content
I’m not involved in oil processing. We are dealing with a type of solid, high-density oil that is solid at room temperature, and its fractured surface is rough； Is it vacuum residue? Is vacuum residue a solid at room temperature? What does it look like? Thank you for the advice.
Vacuum residue is a heavy oil produced from the residues in the petroleum processing process. At room temperature, vacuum residue is usually in a semi-solid or solid state, with high viscosity and density. Vacuum residue typically appears black or dark brown in color, has a relatively hard texture, and sometimes contains certain impurities. The cross-section may appear irregular, rough, or crystalline in shape. It should be noted that there may be differences between different vacuum residues, as their compositions and sources vary widely. Furthermore, depending on the specific treatment methods and conditions, the appearance of vacuum residue can also vary. To more accurately determine whether the solid heavy oil you are encountering is vacuum residue, it is recommended that you conduct tests or have a professional carry out an assessment. .
