Systems and methods for vaporizing hydrocarbons using electrically-powered heating

A hydrocarbon cracking system, the system comprising:

• a feed conduit positioned to supply a feed stream comprising one of a naphtha feed stream or a liquid hydrocarbon feed stream, the one of the naphtha feed stream or the liquid hydrocarbon feed stream comprising carbon numbers ranging from C2 to C15;
• a pre-heating assembly comprising an electrically-powered heater, wherein the pre-heating assembly is in flow communication with the feed conduit and configured to heat the feed stream to provide a pre-heated feed stream comprising one or more of a vaporized portion of the pre-heated feed stream or a pre-heated liquid hydrocarbon feed stream, and a remaining liquid portion of the feed stream;
• a flash device positioned to receive the pre-heated feed stream and separate one or more of a 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;
• a liquid conduit to remove at least a portion of the remaining liquid portion of the feed stream;
• a mixer for adding superheated dilution steam to the at least a portion of the remaining liquid portion of the feed stream to vaporize at least a portion of the remaining liquid portion of the feed stream to supply a mixer outlet stream;
• and
• an electrically-powered steam cracking furnace positioned to receive the flash device outlet stream and the mixer outlet stream, and heat the combined flash device outlet stream and mixer outlet stream to provide a product stream comprising cracked hydrocarbons.
