Processes herein may be used to thermally crack various hydrocarbon feeds, and may eliminate the refinery altogether while making the crude to chemicals process very flexible in terms of crude. In embodiments herein, crude is progressively separated into at least light and heavy fractions. Depending on the quality of the light and heavy fractions, these are routed to one of three upgrading operations, including a fixed bed hydroconversion unit, a fluidized catalytic conversion unit, or a residue hydrocracking unit that may utilize an ebullated bed reactor. Products from the upgrading operations may be used as feed to a steam cracker.

According to one embodiment, a heavy oil may be processed by a method that may include upgrading at least a portion of the heavy oil to form an upgraded oil, where the upgrading includes contacting the heavy oil with a hydrodemetalization catalyst, a transition catalyst, a hydrodenitrogenation catalyst, and a hydrocracking catalyst to remove at least a portion of metals, nitrogen, or aromatics content from the heavy oil and form the upgraded oil. The method may further include passing at least a portion of the upgraded oil to a refinery operation.

Systems and methods for processing heavy oils by oil upgrading followed by refining

According to one embodiment, a heavy oil may be processed by a method that may include upgrading at least a portion of the heavy oil to form an upgraded oil, where the upgrading comprises contacting the heavy oil with a hydrodemetalization catalyst, a transition catalyst, a hydrodenitrogenation catalyst, and a hydrocracking catalyst to remove at least a portion of metals, nitrogen, or aromatics content from the heavy oil and form the upgraded oil. The method may further include passing at least a portion of the upgraded oil to a separation device that separates the upgraded oil into one or more transportation fuels; and where the final boiling point of the upgraded oil is less than or equal to 540&#xb0; C.

Systems and methods for processing heavy oils by oil upgrading followed by distillation

According to one embodiment, a heavy oil may be processed by a method that may include upgrading at least a portion of the heavy oil to form an upgraded oil, where the upgrading includes contacting the heavy oil with a hydrodemetalization catalyst, a transition catalyst, a hydrodenitrogenation catalyst, and a hydrocracking catalyst to remove at least a portion of metals, nitrogen, or aromatics content from the heavy oil and form the upgraded oil; and passing the upgraded oil to a steam cracker and steam cracking the upgraded oil to form a steam-cracked effluent; and where the final boiling point of the upgraded oil is less than or equal to 540&#xb0; C.

Systems and methods for processing heavy oils by oil upgrading followed by steam cracking

According to one embodiment, a heavy oil may be processed by a method that may include upgrading at least a portion of the heavy oil to form an upgraded oil, where the upgrading comprising contacting the heavy oil with a hydrodemetalization catalyst, a transition catalyst, a hydrodenitrogenation catalyst, a first hydrocracking catalyst, and a second hydrocracking catalyst downstream of the first hydrocracking catalyst to remove at least a portion of metals, nitrogen, or aromatics content from the heavy oil and form the upgraded oil. The final boiling point of the upgraded oil may be less than or equal to 540&#xb0; C. The second hydrocracking catalyst cracks at least a portion of vacuum gas oil in the heavy oil. The first hydrocracking catalyst may comprise a greater average pore size than the second hydrocracking catalyst.
