Heavy fossil hydrocarbon conversion and upgrading using radio-frequency or microwave energy

Conversion of heavy fossil hydrocarbons (HFH) to a variety of value-added chemicals and/or fuels can be enhanced using microwave (MW) and/or radio-frequency (RF) energy. Variations of reactants, process parameters, and reactor design can significantly influence the relative distribution of chemicals and fuels generated as the product. In one example, a system for flash microwave conversion of HFH includes a source concentrating microwave or RF energy in a reaction zone having a pressure greater than 0.9 atm, a continuous feed having HFH and a process gas passing through the reaction zone, a HFH-to-liquids catalyst contacting the HFH in at least the reaction zone, and dielectric discharges within the reaction zone. The HFH and the catalyst have a residence time in the reaction zone of less than 30 seconds. In some instances, a plasma can form in or near the reaction zone.

Separation of viscous oils into components

The invention provides methods for treating a source oil phase consisting of heavy oil, bitumen, a mixture of heavy oil and bitumen, a mixture of solvent and heavy oil or bitumen or both. The method comprises: introducing the source oil phase to a heated lower section of a device to provide an interior source oil phase; heating the interior source oil phase so as to thermally separate a light oil phase component therefrom and provide a vaporized light oil; and condensing the vaporized light oil phase on one or more internal cooling fins housed within the upper section of the device, to provide a condensed light oil phase liquid, wherein the internal cooling fins are angled so as to direct the condensed light oil phase liquid downwardly to a light end collection system.

FEEDING PYOIL AND STEAM AT CRACKER FURNACE CROSSOVER

Olefins are made by passing a cracker stream through a convection section of a cracker furnace; introducing steam and a stream comprising a recycle content pyrolysis oil into the cracker stream to form a combined stream, and the steam, r-pyoil stream, or both are introduced downstream of the inlet to the convection section, such as between the inlet to the coils and the radiant zone, or at the cross-over. Additionally, dilution steam can be added to a stream of r-pyrolysis to form a steam-diluted r-pyoil stream which is then introduced into a cracker furnace at any location, such as downstream of the inlets to the convection box or at a cross-over.
