Abstract
The invention provides a process for making a heavy hydrocarbon feed pipeline transportable, said process including blending the heavy hydrocarbon feed with a diluent including a hydrocarbon stream having at least 0.5% by mass of a C4 or lighter hydrocarbon component, said diluent having less than 2% by volume aromatics, wherein the viscosity of the heavy hydrocarbon feed and diluent blend is below 500 cSt at 7.5° C. which is within pipeline transportable limits.

A process for making a heavy hydrocarbon feed pipeline transportable, comprising:
- blending a heavy hydrocarbon feed with a diluent, the diluent comprising:
- a hydrocarbon having at least 0.5% by mass of a C4 or lighter hydrocarbon component;
- and
- less than 2 vol % aromatics,
- whereby a pipeline transportable heavy hydrocarbon feed and diluent blend is obtained, wherein a viscosity of the pipeline transportable heavy hydrocarbon feed and diluent blend is below 500 cSt at 7.5° C.
A pipeline transportable heavy hydrocarbon feed and diluent blend, comprising:
- a heavy hydrocarbon feed;
- and
- a diluent, the diluent comprising:
- a hydrocarbon having at least 0.5% by mass of a C4 or lighter hydrocarbon component;
- and
- less than 2 vol % aromatics,
- wherein a viscosity of the pipeline transportable heavy hydrocarbon feed and diluent blend is below 500 cSt at 7.5° C.
