Embodiment Construction

[0012] In one aspect, embodiments herein relate generally to hydroconversion processes, including processes to hydrocrack resid and other heavy hydrocarbon fractions. More specifically, embodiments disclosed herein relate to hydrocracking of resid hydrocarbon feedstocks, solvent deasphalting of unconverted resid hydrocarbon feedstocks, processing of the resulting hydrocracked hydrocarbon feedstock in a separate resid hydrocracking unit deasphalted oil, and the bitumen from the solvent deasphalted unit is processed in a separate residue hydrocracking unit.

[0013] The hydroconversion process disclosed herein can be used to react a residual hydrocarbon feedstock under conditions of elevated temperature and pressure in the presence of hydrogen and one or more hydroconversion catalysts to convert the feedstock to polluting Lower molecular weight products with reduced levels of compounds such as sulfur and / or nitrogen. Hydroconversion processes may include, for example, hydrogena...

Abstract

A process for upgrading residuum hydrocarbons is disclosed. The process may include: contacting a residuum hydrocarbon fraction and hydrogen with a first hydroconversion catalyst in a first ebullated bed hydroconversion reactor system; recovering a first effluent from the first ebullated bed hydroconversion reactor system; solvent deasphalting a vacuum residuum fraction to produce a deasphalted oil fraction and an asphalt fraction; contacting the deasphalted oil fraction and hydrogen with a second hydroconversion catalyst in a second hydroconversion reactor system; recovering a second effluent from the second hydroconversion reactor system; and fractionating the first effluent from the first ebullated bed hydroconversion reactor system and the second effluent from the second hydroconversion reactor system to recover one or more hydrocarbon fractions and the vacuum residuum fraction in a common fractionation system.

Description

technical field [0001] Embodiments disclosed herein relate generally to hydroconversion processes, including resid and other heavy hydrocarbon fraction hydrocracking processes. More specifically, embodiments disclosed herein relate to hydrocracking of resid hydrocarbon feedstocks, solvent deasphalting of unconverted resid hydrocarbon feedstocks, processing of the resulting hydrocracked hydrocarbon feedstock in a separate resid hydrocracking unit deasphalted oil, and the bitumen from the solvent deasphalted unit is processed in a separate residue hydrocracking unit. Background technique [0002] With the steady increase in worldwide demand for gasoline and other light refined products, there has been a clear trend towards converting high boiling compounds into lower boiling compounds. To meet the increasing demand for distillate fuels, refiners have developed various reactors, such as hydrocracking reactors, residue desulfurization units (RDS) and solvent deasphalting (SDA) ...
