| titleOfInvention | Process to produce process oil with low polyaromatic hydrocarbon content |
| abstract | The preparation of TDAE-1 and TDAE-2 starts from the preparation of a DAE feed having a kinematic viscosity of 24-67 cSt at 100 ° C, which is then mixed with a solvent to form a DAE feed mixture having a density range of 0.75-0.85 kg / And the DAE feed mixture is further contacted with a solvent such as furfural, NMP and DMSO to effect countercurrent liquid-liquid extraction wherein each of TDAE-1 and TDAE-2 is subjected to a ratio of polar solvent: DAE feed mixture 0.0 > 1.7-2.0 < / RTI > and 0.5-1.7. The PCA content of each of TDAE-1 and TDAE-2 is less than 3% by weight and 3-20% by weight. The 8 Grimmer polycyclic aromatic hydrocarbons content in TDAE-1 and TDAE-2 are the same, ie less than 10 mg / kg, and contain less than 1 mg / kg benzo (a) pyrene. |
