Determination of asphalt or heavy oil carbon residue

The main reasons for the spillage of asphalt or heavy oil during heating are as follows: 1. Excessively high temperature: If the heating exceeds the melting point or softening point of asphalt or heavy oil, it will cause them to melt or soften, turning them into a liquid state that can lead to spillage. 2. Improper operation: During the processing, issues such as inaccurate temperature control, too fast or too slow heating rates, or uneven mixing may occur, all of which can lead to the spillage of asphalt or heavy oil during heating. 3. Raw material quality issues: The quality of the asphalt or heavy oil itself can also affect the likelihood of spills. If the raw material contains excessive volatiles or impurities, it will generate gases during heating, causing foam to form on the surface of the asphalt or heavy oil and leading to overflow. 4. Equipment failure: Malfunctions in heating equipment such as temperature controllers or mixing equipment can also lead to the spillage of asphalt or heavy oil during the heating process. The above are some of the common causes of such issues. In practical operations, it is necessary to control the heating temperature and speed properly to ensure the proper functioning of the equipment, as well as to use high-quality raw materials in order to reduce the risk of asphalt or heavy oil leaking during the heating process. .
