Abstract:
1. A method of blending a heavy hydrocarbon residue from a residue hydroconversion process into a pipelineable blend, the method comprising blending the heavy hydrocarbon residue with a virgin bitumen diluted with a diluent and/or a virgin heavy crude oil such that in the produced blend the amount of heavy hydrocarbon residue originating from said residue hydroconversion process is maintained below a predetermined maximum value, wherein the heavy hydrocarbon residue stems from a high conversion catalytic hydroconversion process, operating at a 60-80% conversion rate of the 524° C.+ fraction, that the blending comprises controlling the composition of the heavy 524° C.+ component in the blend such that the blend comprises less than 36 and greater than 30 vol % of heavy 524° C.+ components, which boil at atmospheric pressure at a temperature about 524° C. and that the ratio between the unconverted heavy 524° C.+ components contained in the heavy hydrocarbon residue and the virgin 524° C.+ components contained in the virgin bitumen diluted with diluent and/or virgin heavy crude oil is such that the heavy 524° C.+ heavy hydrocarbon blend comprises between 45 to 75 vol % unconverted heavy 524° C.+ hydrocarbon residue originating from the residue hydroconversion process and the pipelineable blend has a P factor greater than 1, a hot filtration test, according to ASTM D4870, less than 0.15% by weight, and a fouling test result of less than 25% at 400° C.
