Novel Solvent Deasphalting Process by Vacuum Residue ...

The effect of the solvent deasphalting (SDA) process of vacuum residue (VR) blending with coal tar (CT) was studied, and the experimental conditions were optimized. The results revealed that the SDA process was improved by blending with coal tar. The yield of deasphalted oil (DAO) from VR blended with 10% CT was 2.02 wt % higher than that obtained from VR alone.

The acceptability of residual oil as a gas turbine fuel is greatly enhanced in a two step process which significantly decreases the vanadium content of the residual fuel. In the process, the residual oil is first broken down into an oil phase and asphaltene phase by either conventional or supercritical extraction. In this step, the majority of vanadium remains in the asphaltene phase.
