    Abstract: The present disclosure relates to methods of constructing a furnace facility including determining transport parameters including vessel parameters. The method can include determining operating site parameters of an operating site and designing one or more modules based on the vessel and operating site parameters. The modules can be sized to provide length, width, height, weight of the modules within allowance of the vessel and operating site parameters. The modules can be constructed at a module fabrication site before transporting to the operating site via a vessel. One or more modules can have one or more furnace components, and/or one or more modules can have one or more furnace.

    Abstract: The present disclosure provides processes and apparatuses for cracking a hydrocarbon-containing feed. The process includes introducing the hydrocarbon-containing feed to a desalter preheat train having an effluent interchanger. The process includes directing a portion of the hydrocarbon-containing feed from in the desalter preheat train to a feed inlet of a convection section of a steam cracking furnace. The process includes combusting fuel proximate to a plurality of burners that provide thermal energy to a radiant section and a convection section of the steam cracking furnace. The hydrocarbon-containing feed is in an operating mode in the convection section to obtain a heated feed mixture. The process includes separating a bottoms effluent from the heated feed mixture of the convection section in a separator. The process includes cooling the bottoms effluent in a heat exchanger using boiler feed water.

    Abstract: Systems and methods are provided for performing ethane steam cracking at elevated coil inlet pressures and/or elevated coil outlet pressures in small diameter furnace coils. Instead of performing steam cracking of ethane at a coil outlet pressure of ˜22 psig or less (˜150 kPa-g or less), the steam cracking of ethane can be performed in small diameter furnace coils at a coil outlet pressure of 30 psig to 75 psig (˜200 kPa-g to ˜520 kPa-g), or 40 psig to 75 psig (˜270 kPa-g to ˜520 kPa-g). In order to achieve such higher coil outlet pressures, a correspondingly higher coil inlet pressure can also be used, such as a pressure of 45 psig (˜310 kPa-g) or more, or 50 psig (˜340 kPa-g) or more.

    Abstract: Processes and systems for steam cracking hydrocarbon feeds. The process can include introducing a first hydrocarbon feed into radiant coil(s) disposed within a first segment of a firebox to produce a first steam cracker effluent having a first coil outlet temperature. A second hydrocarbon feed can be introduced into radiant coil(s) disposed within a second segment of the firebox to produce a second steam cracker effluent having a second coil outlet temperature. The first and second segments can each include one or more burners providing heat thereto. The burner(s) in each segment can be operated at substantially the same firing rate such that an amount of heat produced by each burner can be substantially the same. A feed rate of the first hydrocarbon feed can be controlled based, at least in part, on a composition of the first hydrocarbon feed and the first coil outlet temperature.

    Abstract: Conduits for cooling a hydrocarbon stream and processes for using same. The conduit can include a first inner wall defining a first bore, a second inner wall defining a second bore, and an outer wall disposed about the first and second inner walls. The conduit can also include an annular support wall connected to an inner surface of the outer wall. An end of the second inner wall and an end of the annular support wall can define a perimeter opening that can be in fluid communication with the second bore. An annular flexible ring can be bonded to the annular support wall and can flexibly contact the first inner wall. A substantially annular cavity can be disposed between the second inner and the outer walls and in fluid communication with the perimeter opening. A quench fluid introduction port can be configured to introduce a quench fluid into the cavity.

    Abstract: A steam cracking process is provided, including introducing a. first hydrocarbon-containing feed to a convection section of a steam cracking furnace. The convection section can include (i) a first arrangement having a first heat exchanger and a first economizer disposed downstream or upstream, of the first heat exchanger: (ii) a second arrangement having a. second heat exchanger in fluid communication with the first heat exchanger and. a second economizer in fluid communication with the first economizer, the second arrangement disposed downstream of the first arrangement such that each of the first and second economizer alternates with each of the first and second heat exchangers. The process can include (a) heating the first hydro-carbon-containing feed in the first heat exchanger at a hydrocarbon outlet temperature and (b) introducing water to the first economizer and removing the water from the convection section at an outlet temperature.
