Abstract: An exhaust steam stream having an absolute pressure from 200 kPa to 1,050 kPa and shaft power are produced from an extraction turbine and/or a back-pressure turbine. The exhaust steam stream can be supplied to an amine regenerator of an amine CO2 separation process. The shaft power can be utilized to drive equipment in a hydrocarbon processing plant such as an olefins production plant.

Abstract: 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.

Abstract: Processes for removing deposits from a pump-around loop or simply loop. The process can include isolating a first and a second end of the loop in fluid communication with a vessel to provide an isolated section. The isolated section can include a first conduit disposed within a convection section of a steam cracking furnace or a heat exchanger that is external to the steam cracking furnace that can include char therein. The first end can be connected to an aqueous fluid/oxidant source. The second end can be connected to a second conduit disposed within the convection section. An aqueous fluid/oxidant mixture can be introduced into the first end that can be heated by flowing through the isolated section. The heated mixture can flow through the second conduit to produce a second heated mixture that can be introduced into a radiant section of the steam cracking furnace.
