Abstract: A system and method for cracking hydrocarbon feed streams may include a pre-heating assembly configured to heat the hydrocarbon feed stream to provide a pre-heated feed stream including a vaporized portion and a pre-heated liquid portion. The pre-heating assembly may include an electrically-powered heater, an electrically-powered heater and a steam heater, or an electrically-powered heater and heat transfer fluid configured to heat the feed stream. The pre-heating assembly also may include a flash device positioned to receive the vaporized portion and the pre-heated liquid portion and separate the vaporized portion of the pre-heated feed stream or the pre-heated liquid hydrocarbon feed stream from the remaining liquid portion of the feed stream to supply a flash device outlet stream. The system further may include a steam cracking furnace positioned to receive the flash device outlet stream and heat the flash outlet device stream to provide a product stream including cracked hydrocarbons.
