Abstract
Embodiments of the present disclosure are directed to a process for producing upgraded product from residue comprising atmospheric residue or vacuum residue upgrading 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.
