Heavy crude upgrading using remote natural gas

Patent ·
OSTI ID:5595897
This paper describes a method of forming an upgraded crude. It comprises: forming hydrogen from methane gas for hydroconverting heavy crude to form a better crude and reduce its viscosity; hydrogenating under hydroconverting conditions of 650 degrees Fahrenheit ({degrees}F)-1000{degrees}F; and 500-3000 pounds per square inch gauge (psig) only a first portion of a crude oil stream less than the total crude oil stream to produce a light oil that has a lowered viscosity; admixing the light oil with the remainder of the crude oil stream not hydrogenated to produce a flowable crude; and transporting the flowable crude to a refinery including a substep of flowing the crude through a pipeline.
