Abstract
A process for producing paraffin extracted clarified slurry oil (raffinate) with improved aromaticity from the feed stock such as clarified slurry oil (CSO) is provided. The obtained paraffin extracted clarified slurry oil with improved aromaticity is suitable for a variety of industrial applications. For example, it can be used as a valuable feedstock for producing carbon black.
Claims10
A process for producing raffinate with improved aromaticity;
- said process comprising the following steps:
- a. mixing raffinate feedstock having a BMCI ranging between 110 and 130 with a solvent in an apparatus to obtain an oil-solvent mixture;
- b. heating the oil-solvent mixture at a temperature ranging between 50 and 200° C. to obtain a heated oil-solvent mixture;
- c. vigorously agitating the heated oil-solvent mixture for a time period ranging between 0.5 and 2 hours to obtain an oil-solvent dispersion;
- d. allowing the dispersion to separate into paraffin rich phase and raffinate phase;
- e. separating the raffinate phase from the paraffin rich phase to obtain raffinate with aromatics content of at least 90 wt % and a BMCI of at least 132.
