FISCHER-TROPSCH DERIVED HEAVY HYDROCARBON DILUENT

摘要

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 500cSt at 7.5°C which is within pipeline transportable limits.
