摘要： An electrically powered furnace and related methods may include an electrically powered furnace having an output of at least one megawatt with a control system; a furnace housing comprising one or more housing walls at least partially defining an interior volume; a plurality of heating zones within the interior volume; and a plurality of heated tubes extending in the interior volume. A method may include providing the feed to the electrically powered furnace; and algorithmically adjusting the output of the one or more heating elements for each of the plurality of heating zones to heat the feed to a desired temperature while maintaining temperatures of the one or more heating elements within predetermined parameters.

摘要： A system and a method for steam cracking hydrocarbons are disclosed. The system includes a steam cracking system comprising a first steam cracking furnace and a second steam cracking furnace. A hydrocarbon feed stream is fed into a convection section of a first steam cracking furnace. The preheated feed stream is mixed with steam and then separated into a light vapor stream and a heavy stream in a vapor-liquid separation unit. The light vapor stream is further steam cracked in a radiant section of the first steam cracking furnace. The heavy stream is further heated and steam cracked in the second steam cracking furnace.

摘要： Methods and system for superheating dilution steam for use in a steam cracking furnace and generating electricity are provided. Methods can include combusting fuel in the presence of compressed air to produce a flue gas, wherein the flue gas drives a turbine to produce electricity. Methods can further include superheating the dilution steam with the flue gas, combining the dilution steam with a feed stream including hydrocarbons to produce a mixed feed stream, and steam cracking the mixed feed stream to produce a product stream.
