Abstract (en)
[origin: US2019233746A1] Solvent deasphalting (SDA) is used to extract deasphalted oil from heavier hydrocarbons in series. The pitch stream from solvent deasphalting is calcined to recover volatile hydrocarbon vapor products and calcined solids. The hydrocarbon vapors can be fractionated to recover valuable transportation range fuel products. The pitch stream can be first fed to the fractionation column before calcination.
