Control of residual carbon in vacuum residue
Thread Content
For this recent batch of oil, the mass yield at 520°C for vacuum residue is 4.02%, the carbon residue level is around 12.5, and the softening point is 33； Is there a problem? How should adjustments be made in such a situation?
The softening point can be used to adjust the flow rate of the degreasing oil; changes in flow rate affect the softening point of the substrate
