  • Patent number: 11976245
    Abstract: Processes herein may be used to thermally crack various hydrocarbon feeds, and may eliminate the refinery altogether while making the crude to chemicals process very flexible in terms of crude. In embodiments herein, crude is progressively separated into at least light and heavy fractions. Depending on the quality of the light and heavy fractions, these are routed to one of three upgrading operations, including a fixed bed hydroconversion unit, a fluidized catalytic conversion unit, or a residue hydrocracking unit that may utilize an ebullated bed reactor. Products from the upgrading operations may be used as feed to a steam cracker.

  • Publication number: 20240124374
    Abstract: Systems and processes for converting light or very light sweet crudes and condensates to chemicals and petrochemicals. The process includes providing a hydrocarbon feedstock comprising a crude oil or condensate having an API gravity of at least 35, a sulfur content of less than 0.2 wt %, and less than 10 wt % of hydrocarbons having a normal boiling point above 575° C. The hydrocarbon feedstock is heated and separated to recover a light fraction, a middle fraction, and optionally a heavy fraction. The light fraction is steam cracked to produce a cracked light fraction and the middle fraction is separately steam cracked to produce a cracked middle fraction. The cracked light fraction and the cracked middle fraction are then separated to recover one or more product fractions including an ethylene fraction and a propylene fraction.

  • Publication number: 20240124375
    Abstract: A process for dehydrogenating a paraffinic feedstock, producing olefins and/or dienes. The process includes feeding a paraffinic hydrocarbon feedstock comprising one or more C2+ paraffinic hydrocarbons and a fuel gas stream to a dehydrogenation reactor preheater, combusting the fuel gas stream in the dehydrogenation reactor preheater and heating the paraffinic hydrocarbon feedstock to a temperature in the range of 500-650° C., producing a heated paraffinic feedstock, feeding the heated paraffinic feedstock to a first dehydrogenation reactor operating in a reaction mode and containing an active dehydrogenation catalyst and at least one first electrical heating element, heating the heated paraffinic feedstock in the first dehydrogenation reactor using the at least one first electrical heating element, and contacting the heated paraffinic feedstock with the active dehydrogenation catalyst and the at least one electrical heating element thereby producing an olefinic product stream comprising one or more olefins.

  • Patent number: 11959032
    Abstract: A process for steam cracking a whole crude including a volatilization step performed to maintain a relatively large hydrocarbon droplet size. The process may include contacting a whole crude with steam to volatilize a portion of the hydrocarbons, wherein the contacting of the hydrocarbon feedstock and steam is conducted at an initial relative velocity of less than 30 m/s, for example. The resulting vapor phase, including volatilized hydrocarbons and steam may then be separated from a liquid phase comprising unvaporized hydrocarbons. The hydrocarbons in the vapor phase may then be forwarded to a steam pyrolysis reactor for steam cracking of the hydrocarbons in the vapor phase.
