Abstract:
Solvent deasphalting (SDA) in series is used to extract deasphalted oil from heavier hydrocarbons in series. Instead of stripping the pitch material of solvent in the second stage which can stick in the pitch stripper and inhibit flow, a dryer is used to vaporize solvent for recycle to the second SDA unit and produce pitch solids.
