Heavy oil extraction ups FCC feed out first-stage grass roots ROSE unit, in Kansas
This paper describes operation of a residuum oil supercritical extraction unit which produces oils, resins, and high asphaltene pitch from feedstocks ranging from partially topped crude to vacuum-reduced and brown asphalts. Deasphalted oil products (DAO) are substantially lower in metals, carbon residue, and other impurities than the feedstock. Vacuum bottoms are charged to a fixed element in-line mixer where the vacuum bottoms are contacted with several volumes of solvent at elevated temperature and pressure. Carryover of product droplets from flash drums and strippers into solvent condensers and coolers resulted in frequent plugging of fin-fan tubes with subsequent shutdown for physical cleanout. Installation of a small superheater on the stripping steam solved the problem. DAO is mixed with atmospheric and vacuum gas oils and fed to an FCC unit. Overall metals content of this mixed gas oil stream has increased with DAO.
