ON-LINE DETERMINATION OF THE FLASH POINT OF LUBE OIL FRACTIONS FRACTIONS ON-LINE DETERMINATION OF THE FLASH POINT OF LUBE OIL

摘要

Apparatus provides for an on-line determination of the flash point of lube oil fractions. The hydrocarbon is continuously sampled by a viscosity analyzer and a density analyzer which provides signals corresponding to the viscosity and the API gravity of the lube oil fractions. A computer circuit provides a signal corresponding to the flash point of the lube oil fractions in accordance with the viscosity signal and the gravity signal.
