  • Process for manufacturing of rubber process oils with extremely low carcinogenic polycyclic aromatics compounds
    Patent number: 9932529
    Abstract: The invention discloses a rubber process oil and a process for manufacturing rubber process oils which are non-carcinogenic in nature. The process comprises of selectively producing Hildebrand solubility components enriched vacuum residue by selective distillation of reduced crude oil (RCO) to obtain minimum of 10 vol % boiling components in the range 490° C. to 50° C., which leads to higher solubility of rubber process oil with an aniline point of less than 70° C. and with extremely low concentration of selective polycyclic aromatics which makes the 15 product non-carcinogenic.
    Type: Grant
    Filed: February 2, 2013
    Date of Patent: April 3, 2018
    Assignee: INDIAN OIL CORPORATION LTD.
