Abstract: Integrated processes and systems for the production of distillate hydrocarbons and coke. The process may include feeding a hydrocarbon feedstock, comprising a residuum hydrocarbon fraction, to a residue hydrocracking reactor system to convert hydrocarbons therein, producing a hydrocracked effluent. The hydrocracked effluent may then be fed to a separation system, separating the hydrocracked effluent into one or more distillate hydrocarbon fractions and a vacuum residue fraction. The vacuum residue fraction may be fed to a coker system, converting the vacuum residue fraction into a coke product and a coker vapor effluent, recovering the coke product, and feeding the coker vapor effluent to the separation system. The one or more distillate hydrocarbon fractions are hydroprocessed to produce a hydroprocessed effluent, and the hydroprocessed effluent is separated into product distillate hydrocarbon fractions.

Abstract: A method for functionalizing a surface of a dielectric plate that is transparent to visible light—to be able to examine the dielectric plate using optical microscopy—includes depositing a negative film on the dielectric slide. The negative film comprises a polymerizable composition that polymerizes when exposed to an electron beam. The polymerizable composition is polymerized—by exposing the negative film to the electronic beam—at a set of points representing a preset pattern. Non-polymerized portions of the polymerizable composition are dissolved—to develop the negative film—forming a set of pads of polymerized portions of the polymerizable composition. Each pad corresponds to one point of the preset pattern. A metal film is disposed on the negative film, and the developed negative film is dissolved to define holes through the metal film. Each of the holes corresponds to a base of one pad of the set of pads.

Abstract: System, apparatuses, and methods for processing feedstock have a decomposing stage for breaking down feedstock into liquid and gaseous products and a condensing stage for condensing gaseous products to a liquid condensate. A mixing stage can also be used to combine gaseous and liquid feedstock portions into a combined liquid feedstock to be fed to the decomposing stage. The decomposing stage can be one or more flux tanks having a field generator for creating an electromagnetic field through the flux tank configured to decompose feedstock inside. The condensing stage can have a catalyst tank, distillation tank, condensing pipes, or a combination thereof. The mixing stage can be a reformer device having pairs of plates, at least some of the plates are capable of rotating to generate a shear force that creates a cavitation effect to combine the gaseous and liquid feedstock portions.

Abstract: The process removes hydrogen sulfide from hydrotreated gas by TSA. Hydrogen sulfide adsorbs on the adsorbent while allowing hydrogen in the hydrotreated gas to pass the adsorbent to provide a desulfided hydrogen gas stream and a sulfided adsorbent. A regenerant gas stream can be contacted with the sulfided adsorbent at a swing temperature to desorb hydrogen sulfide from the adsorbent into the regenerant gas stream. The regenerant gas stream can then be recycled to a hydrotreating reactor for processing biorenewable feed to provide hydrogen sulfide to the reactor. The desulfided gas stream can be purified to remove impurities such as carbon oxides and recycled to the hydrotreating reactor and/or used as the regenerant gas stream.

Abstract: A catalytic upgrading process includes introducing a feed comprising crude oil to a first catalytic deasphalting reactor to deasphalt the feed, thereby producing polymerized asphaltenes and deasphalted oil (DAO). The DAO is introduced to a steam cracking unit, thereby producing pyrolysis gas (PG), which is introduced into a selective hydrogenation unit, thereby producing an olefin-free product, which can then be introduced to a separation unit. The resulting benzene-toluene-xylenes (BTX)-containing stream and liquid petroleum gas (LPG) are separated, and the BTX-containing stream is introduced to a BTX complex to produce refined BTX. After deasphalting, a wash solvent may be introduced into the first catalytic deasphalting reactor to remove the polymerized asphaltenes, regenerate the catalyst, and produce a mixture comprising the wash solvent and the polymerized asphaltenes. The wash solvent is separated from the polymerized asphaltenes.

Abstract: The invention relates to an improved system and method for relief of hot, high pressure, fouling fluid from the 1st Stage Reactor and the ISS in case of an unintended overpressure situation while allowing the quick establishing of normal fluid flow path once the overpressure situation has been corrected. This allows for rapid cooling of all subsequent reactor stages while minimizing VGO slop generation that needs reprocessing.

Abstract: A process for treating a hydrocarbon stream to remove polynuclear aromatic (PNA) and heavy polynuclear aromatic (HPNA) compounds includes contacting the hydrocarbon stream with an adsorbent in an adsorption unit to adsorb the PNA and HPNA compounds onto the adsorbent to produce a treated hydrocarbon stream and regenerating the adsorbent. Regenerating the adsorbent may include contacting the adsorbent with a solvent comprising a disulfide oil, such as a disulfide oil effluent from a mercaptan oxidation unit. The solvent comprising the disulfide oil desorbs the PNA and HPNA compounds from the adsorbent into the solvent to produce a desorption effluent. The treated hydrocarbon stream can be passed to a hydrocracking unit that hydrocracks the treated hydrocarbon stream to produce a hydrocracker effluent that includes greater value petrochemical products or intermediates.
