Process for treating a heavy hydrocarbon feedstock and a product obtained therefrom

摘要

A process for treating a heavy hydrocarbon feedstock is disclosed. The process involves separating the feedstock into a residue component and a light component, the residue component having a lower API gravity than the light component and treating at least a portion of the light component to produce a synthetic transport diluent suitable for combining with at least a portion of the residue component to produce a product which meets applicable criteria for pipeline transport.

主权项

1. A product obtained from a heavy hydrocarbon feedstock, said product meeting applicable criteria for pipeline transport, said product comprising:
an amount of a residue component separated from said feedstock which includes substantially all asphaltenes of the feedstock, having an API gravity of between about −20° and about 10° and a nickel and vanadium content of 400-600 ppm wt; and an amount of a synthetic transport diluent produced from said feedstock and treated to have an API gravity of between about 20° and about 80°; wherein the heavy hydrocarbon feedstock has a nickel and vanadium content of 100-400 ppm wt, the product has a nickel and vanadium content of 190-235 ppm wt and the residue component in the product constitutes 25-75% by volume of the product.
