Abstract: Systems and methods to enhance vaporization of a hydrocarbon feed may include an evaporator positioned to receive a hydrocarbon feed and partially evaporate the hydrocarbon feed to provide a gaseous hydrocarbon portion and a liquid hydrocarbon portion. A first mixing unit may be positioned to receive the gaseous hydrocarbon portion and dilution steam and provide a hydrocarbon-steam mixture. A heater may be positioned to receive the hydrocarbon-steam mixture to provide a heated hydrocarbon-steam mixture. A second mixing unit may be positioned to receive the liquid hydrocarbon portion and the heated hydrocarbon-steam mixture STEAM and to evaporate at least a portion of the liquid hydrocarbon portion via energy associated with the heated hydrocarbon-steam mixture to provide one or more of an evaporated hydrocarbon portion or a heated liquid hydrocarbon portion.

Abstract: 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.

Abstract: The presently disclosed subject matter relates to methods and systems for purifying 1,3-butadiene from a C4 hydrocarbon stream. An example method includes introducing a C4 hydrocarbon stream including 1,3-butadiene and acetlyenes to an organic azide in the presence of a catalyst to generate a first stream including triazole, separating triazole from the first stream to produce a second stream including 1,3-butadiene, and distilling 1,3-butadiene from the second stream to produce a purified 1,3-butadiene product stream.
