Patent number: 11767477Abstract: 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.Type: GrantFiled: August 14, 2020Date of Patent: September 26, 2023Assignee: EXXONMOBIL TECHNOLOGY AND ENGINEERING COMPANYInventors: Eric B. Shen, Anjaneya S Kovvali, Aruna Ramkrishnan, Arun K. Sharma, Samuel J. Cady, Stephen H. Brown, Rustom M. Billimoria, Brenda A. Raich, Bryan A. Patel, Phillip K. Schoch, John Della Mora

Patent number: 11760942Abstract: 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.Type: GrantFiled: August 14, 2020Date of Patent: September 19, 2023Assignee: EXXONMOBIL TECHNOLOGY AND ENGINEERING COMPANYInventors: Stephen H.

Publication number: 20220315844Abstract: Systems and methods are provided for performing slurry hydroconversion of feeds that include substantial amounts of 1050° F+ (566° C+) components. The productivity of the slurry hydroconversion reaction is improved by recycling slurry hydroconversion pitch or bottoms back to the slurry hydroprocessing reaction system. The mass flow rate of the recycle stream can correspond to 50% or more of the mass flow rate of the fresh feed to the reaction system, and the recycle stream can include more than 50 wt % of 566° C+ components. It has been discovered that using a substantial recycle stream composed of a majority of unconverted 566° C+ bottoms can increase the productivity of the slurry hydroprocessing reaction system when operating at a net conversion relative to 524° C (975° F) of less than 90 wt %.Type: ApplicationFiled: August 14, 2020Publication date: October 6, 2022Applicant: EXXONMOBIL TECHNOLOGY AND ENGINEERING COMPANYInventors: Samuel J.
