Abstract: A system for processing plastic waste may include a feed line, a feed fractionator, a hydrotreater, a catalytic reforming unit, a heavy oil cracker, and a steam cracker. A pyrolyzed plastics feed is separated into light, medium, and heavy hydrocarbon streams. The hydrotreater removes sulfur, and the catalytic reforming unit produces a circular aromatic-rich stream. The heavy oil cracker generates cracked streams. The steam cracker produces a circular olefin stream from a cracked stream. A system for processing plastic waste may include the feed line, the feed fractionator, the hydrotreater, a medium hydrocarbon fractionator, the catalytic reforming unit, a full-range reforming unit, the heavy oil cracker, and the steam cracker. The medium hydrocarbon fractionator produces two hydrocarbon streams. The full-range naphtha reforming unit produces a second circular aromatic-rich stream.

Abstract: A method comprising the steps of feeding condensate to a splitter unit; directing the resulting naphtha product to a naphtha hydrotreater and the resulting diesel product to a diesel hydrotreater; directing ULSD product from the diesel hydrotreater to ULSD storage and naphtha product from the diesel hydrotreater to the naphtha hydrotreater; directing treated naphtha product from the naphtha hydrotreater to a naphtha splitter; isomerizing the light naphtha product and reforming the heavy naphtha product; sending the isomerate and the reformate to a gasoline separator; directing the products to storage.

Abstract: Turbine fuel provided for large-scale land based turbines used by utilities for producing electricity and desalinated water, and for large mobile engines and turbines in marine and remote applications where only liquid fuels are available. Use results in less corrosion, ash formation and emissions (NOx, SOx, CO2 and noxious metals) than firing contaminated heavy crude, refinery residual oils or high sulfur fuel oils. Manufacture is by decontaminating crude oils, non-conventional crudes, and other highly contaminated feeds. Each fuel is produced as a single product of unit operations, not ex-plant blend of various refinery products, yet using an apparatus configuration less complex than conventional crude oil refining. These fuels can be fired by advanced high efficiency turbines of combined cycle power plants having hot flow paths and heat recovery steam generation systems susceptible to corrosion, which systems cannot otherwise risk contaminated heavy crudes or refinery residual oils feeds.

Abstract: A process for producing cracked hydrocarbons from a feedstock, which includes a top portion that boils below 375° C. and a bottom portion that boils above 375° C., may include stripping the feedstock in a stripper to isolate the top portion from the bottom portion, hydrocracking the bottom portion in one or more hydrocracking reactors to produce a hydrocracked effluent, separating the hydrocracked effluent in a separating unit to produce a light product stream, a distillate stream, and a heavy unconverted stream; and recycling the heavy unconverted stream to an earlier stage of the process.

Abstract: The invention describes and claims a processing plant and a method for processing viscous oil and oil products. The processing is effectuated with a plant, which comprises a plurality of reaction modules, a plurality of rectifying chambers and pipelines. Each reaction module and each rectifying chamber comprises a tank, a pump, a hydrocavitation generator. Each reaction module comprises a plurality of intermediate reaction stages. Each rectifying chamber comprises a plurality of intermediate rectifying stages. The reaction module and the rectifying chamber are interconnected. Intermediate reaction stages are connected by pipelines, with the last one connected to a rectifying chamber.

Abstract: Deep desulfurization of hydrocarbon feeds containing undesired organosulfur compounds to produce a hydrocarbon product having low levels of sulfur, i.e., 15 ppmw or less of sulfur, is achieved by with an apparatus arranged for flashing the feed at a target cut point temperature to obtain two fractions. A low boiling temperature fraction contains refractory, sterically hindered sulfur-containing compounds, which have a boiling point at or above the target cut point temperature. A high boiling temperature fraction, having a boiling point below the target cut point temperature, is substantially free of refractory sulfur-containing compounds. The high boiling temperature fraction is contacted with isomerization catalyst, and the isomerized effluent and the low boiling temperature fraction are combined and contacted with a hydrotreating catalyst in a hydrodesulfurization reaction zone operating under mild conditions to reduce the quantity of organosulfur compounds to an ultra-low level.

Abstract: An oxidative treatment process, e.g., oxidative desulfurization or denitrification, is provided in which the oxidant is produced in-situ using an aromatic-rich portion of the original liquid hydrocarbon feedstock. The process reduces or replaces the need for the separate introduction of liquid oxidants such as hydrogen peroxide, organic peroxide and organic hydroperoxide in an oxidative treatment process.
