Patent ID: 8613852

Claim:
A process for producing a stable self-compatible hydrocarbon product stream, comprising: performing a conversion process on a heavy oils feedstream with an API gravity of less than about 19 to produce a conversion product stream comprised of a conversion product stream having an API gravity of at least about 20; adding an incompatibility stream having a T5 boiling point of at least 80° F. and a T95 boiling point less than about 450° F. (232° C.) to the conversion product stream to form a mixed conversion stream; washing the mixed conversion stream with water to remove precipitated solids from the mixed conversion stream thereby forming a washed product stream; separating the washed product stream into a self-compatible product stream and a light ends fraction; and storing at least a portion of the light ends fraction in a vessel; wherein the incompatibility stream is comprised of at least a portion of the light ends fraction and the light ends fraction comprises at least a lowest boiling 2% by volume of the washed product stream and having a T5 boiling point of at least 80° F. and a T95 boiling point less than about 450° F. (232° C.).
