Up-gradation of FCC Recycle Oil through Solvent Extraction

This process is a combination of two processes namely Solvent Extraction and Fluid Catalytic Cracking (FCC). In this process, the bottom of FCC unit i.e. Clarified Oil is solvent extracted. The paraffinic rich raffinate is used as a feed for FCC. This generates additional feed for FCC unit. This addition clean FCC feed gives improved distillate yield and removes polyaromatics (precursors for coke) from FCC feed. The process lowers the coke build up on the catalyst also.
