Abstract: Systems and methods are provided for partial upgrading of heavy hydrocarbon feeds to meet transport specifications, such as pipeline transport specifications. The systems and methods can allow for one or more types of improvement in heavy hydrocarbon processing prior to transport. In some aspects, the systems and methods can produce a partially upgraded heavy hydrocarbon product that satisfies one or more transport specifications while incorporating an increased amount of vacuum gas oil and a reduced amount of pitch into the partially upgraded heavy hydrocarbon product. In other aspects, the systems and methods can allow for increased incorporation of hydrocarbons into the fraction upgraded for transport, thereby reducing or minimizing the amount of hydrocarbons requiring an alternative method of disposal or transport. In still other aspects, the systems and methods can allow for reduced incorporation of external streams into the final product for transport while still satisfying one or more target properties.

Abstract: An upgraded crude composition is provided, along with systems and methods for making such a composition. The upgraded crude composition can include an unexpectedly high percentage of vacuum gas oil boiling range components while having a reduce or minimized amount of components boiling above 593° C. (1100° F.). In some aspects, based in part on the hydroprocessing used to form the upgraded crude composition, the composition can include unexpectedly high contents of nitrogen. Still other unexpected features of the composition can include, but are not limited to, an unexpectedly high nitrogen content in the naphtha fraction; and an unexpected vacuum gas oil fraction including an unexpectedly high content of polynuclear aromatics, an unexpectedly high content of waxy, paraffinic compounds, and/or an unexpectedly high content of n-pentane asphaltenes.
