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.

A process for upgrading a hydrocarbon-based composition that includes combining a supercritical water stream, a hydrogen stream, and a pressurized, heated hydrocarbon-based composition in a mixing device to create a combined feed stream. The process further includes introducing the combined feed stream into a supercritical water hydrogenation reactor operating at a temperature greater than a critical temperature of water and a pressure greater than a critical pressure of water, and at least partially converting the combined feed stream to an upgraded product.
