摘要： In accordance with one or more embodiments herein, an integrated process for upgrading a hydrocarbon oil feed stream utilizing a delayed coker, steam enhanced catalytic cracker, and an aromatics complex includes solvent deasphalting the hydrocarbon oil stream; delayed coking the heavy residual hydrocarbons; hydrotreating the delayed coker product stream and the deasphalted oil stream to form a light C5+ hydrocarbon stream and a heavy C5+ hydrocarbon stream; steam enhanced catalytically cracking the light C5+ hydrocarbon stream; steam enhanced catalytically cracking the heavy C5+ hydrocarbon stream; passing at least a portion of the light steam enhanced catalytically cracked stream, the heavy steam enhanced catalytically cracked stream, or both to a product separator to produce a olefin product stream, a naphtha product stream, and a BTX product stream; and processing the naphtha product stream in the aromatics complex to produce benzene and xylenes.

摘要： A method for converting an ultra low sulfur diesel fuel to a kerosene product includes receiving an ultra low sulfur diesel fuel within a reaction vessel, delivering a gas through one or more spargers positioned within a reaction vessel into the ultra low sulfur diesel fuel so as to form aerosol droplets, passing the aerosol droplets through one or more catalyst grids positioned within the reaction vessel at a level above the ultra low sulfur diesel fuel at a speed between 0.01 m/s and 0.7 m/s, collecting a product gas resulting from the passing of the aerosol droplets through the catalyst grids, and condensing the product gas to form a kerosene product.

摘要： 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.

摘要： Disclosed herein is an improved fluidized catalytic cracking process for converting normally liquid hydrocarbon feedstock with simultaneous reduction of sulfur content in the liquid products obtained therefrom which comprises carrying out the cracking process in the presence of carbon monoxide gas as a reducing agent. The process optionally includes a step of premixing the hydrocarbon feedstock with carbon monoxide gas causing major sulfur reduction before effecting the cracking. The premixing is done in a specified nozzle assembly linked to the FCC unit.

摘要： A process for cracking a heavy hydrocarbon feed comprising a vaporization step, a catalytic cracking step, a hydrotreating step, and a steam cracking step is disclosed. The heavy hydrocarbon feed is passed to a first zone of a vaporization unit to separate a first vapor stream and a first liquid stream. The first liquid stream is passed to a second zone of the vaporization unit and contacted with a counter-current steam to produce a second vapor stream and a second liquid stream. The first vapor stream and the second vapor stream are cracked in the radiant section of the steam cracker to produce a cracked effluent. The second liquid stream is catalytically cracked to produce a cracked product. The cracked product is distilled to produce a overhead stream, a light cycle oil, and a heavy cycle oil. The light cycle oil is reacted with hydrogen in the presence of a catalyst to produce a hydrotreated light cycle oil. The hydrotreated light cycle oil and the overhead stream are fed to the vaporization unit.
