1. A process for producing upgraded product from residue comprising atmospheric residue or vacuum residue upgrading, the process comprising:
separating the residue through a Solvent Deasphalting (SDA) unit, wherein the SDA unit includes an asphaltene separator that separates the residue into asphaltene pitch and a stream comprising deasphalted oil (DAO) and resin, and a resin separator that subsequently separates the stream comprising DAO and resin into separate DAO and resin streams;
treating the resin stream with supercritical water (SCW) to produce an upgraded resin stream; and
hydroprocessing a portion of the upgraded resin stream and the DAO stream to produce the upgraded product.
