Processes and Systems for Co-Processing a Hydrocarbon Feed and a Heavy Feed Containing a Plastic Material - A simplified explanation of the abstract

This abstract first appeared for US patent application 18405088 titled 'Processes and Systems for Co-Processing a Hydrocarbon Feed and a Heavy Feed Containing a Plastic Material

The patent application describes processes and systems for hydrocarbon pyrolysis, where a hydrocarbon is heated within a convection section of a steam cracking furnace and combined with an aqueous fluid to produce a heated mixture. A heavy feed containing plastic material is cracked in a vessel to obtain liquid and vapor effluents. The liquid effluent is heated and recycled back to the vessel, while the vapor effluent is combined with the heated mixture to produce a combined mixture that is further heated in the convection section. The heated combined mixture is then cracked in a radiant section of the steam cracking furnace to produce a steam cracker effluent.

• Heating hydrocarbons in a convection section of a steam cracking furnace

Original Abstract Submitted

Processes and systems for hydrocarbon pyrolysis. In some embodiments, a hydrocarbon can be heated within a convection section of a steam cracking furnace and combined with an aqueous fluid to produce a heated mixture. A heavy feed that includes a plastic material can be introduced into a vessel and a portion of the plastic material can be cracked therein. Liquid and vapor effluents exiting the vessel can be obtained. At least a portion of the liquid effluent can be heated to produce a heated fluid stream that can be recycled to the vessel. The vapor effluent can be combined with the heated mixture to produce a combined mixture that can be heated within the convection section to produce a heated combined mixture. At least a portion of the heated combined mixture can be cracked within a radiant section of the steam cracking furnace to produce a steam cracker effluent.
