CONFIGURATION FOR OLEFINS PRODUCTION

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.

Hydroprocessing reactor internals having reduced height
10668442 · 2020-06-02 · ·

The hydroprocessing reactor internals (HRI) have reduced height compared to standard HRI designs. The HRI height reduction is achieved by a more open design of a rough liquid distribution tray so that the required spaces above and below the tray for vapor flow are reduced. The hydroprocessing reactor quench zone internals comprise a collection tray, a rough liquid distribution tray, and a vapor-liquid distribution tray. Fluid mixing occurs above both the collection tray and the rough liquid distribution tray.

HYDROPROCESSING SYSTEM WITH IMPROVED COOLING LIQUID ATOMIZATION
20200156094 · 2020-05-21 ·

A hydroprocessing system having a processing vessel that discharges a high temperature effluent that must be cooled prior to collection in a reflux drum. One or more gas assisted spray nozzle are provided that utilize light atomizing gas having a density of 8-15 times less than air, such as hydrogen, which preferably is the processing or recycle gas of the system. The spray nozzles are designed for the efficient atomization and direction of cooling water into a micron sized droplet distribution utilizing the light atomizing gas for affecting higher mass and heat transfer from the effluent. The spray nozzles each include a unique atomizing gas and cooling liquid passageway systems, a downstream impingement post, and a plurality of discharge orifices which sequentially breakdown the liquid into micron sized droplets as low as 500 microns and less.
