摘要： 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.

摘要： In the hydrocracking process in accordance with the invention, which comprises a hydrocracking section, a high pressure hot separator and a fractionation section, upstream of the fractionation section, a stripper or reboiler column type separation column is added which treats at least a portion of the heavy effluent obtained from the high pressure hot separator. All or a portion of the bottom fraction from said column, which is rich in polynuclear aromatic compounds, is purged. At least a portion of the bottom fraction obtained from the fractionation section, which is constituted by unconverted products, is recycled to the reaction section.

摘要： Provided are a vacuum rectification tower with a satellite-type tower kettle and a vacuum rectification method for atmospheric pressure residual oil. The vacuum rectification tower includes a satellite-surrounded vacuum tower kettle and a rectifying section; the satellite-surrounded vacuum tower kettle includes a main tower kettle and a plurality of sub-reactors arranged outside the main tower kettle in a satellite-surrounded mode; the main tower kettle is provided with a first outlet and a plurality of spray inlets, and a top portion of the main tower kettle has an opening; the sub-reactor is provided with a second outlet and a first inlet, the spray inlets are connected with the second outlets of each sub-reactor in a one-to-one correspondence, and the first outlet is connected with the first inlets. The above vacuum rectification tower is used for treating the atmospheric pressure residual oil, and an extraction rate of light oil may be effectively improved under relatively mild temperature and pressure environment.

摘要： Systems and methods for producing one or more olefins using waste plastics and used lubricating oil are disclosed. Mixed waste plastic is processed in a pyrolysis unit to produce plastic derived oil. The plastic derived oil is subsequently blended with used lubricating oil to form a mixture. The mixture is then separated into (1) a light-end stream comprising C1 to C8 hydrocarbons and (2) a heavy hydrocarbon feed stream. The heavy hydrocarbon feed stream is then processed to produce a steam cracking feedstock stream. The light end-stream and/or the steam cracking feedstock stream are then flowed into a cracking unit to produce one or more olefins.

摘要： Process scheme configurations are disclosed that enable deep hydrogenation of middle distillates. The hydrogenated middle distillates are processed in a steam cracker for conversion into light olefins. Feeds to the deep hydrogenation zone include diesel range streams from a diesel hydrotreating zone, a gas oil hydroprocessing zone, and/or a vacuum residue hydrocracking zone. The deep hydrogenation zone operates under conditions effective to reduce aromatic content in a diesel range feedstream from a range of about 10-40 wt % or greater, to a hydrogenated distillate range intermediate product having an aromatic content of less than about 5-0.5 wt %.

摘要： Optimized, heat-integrated methods and systems are provided to produce multiple, high-value products from oil shale, while minimizing overall energy and water usage. A method for producing multiple products from oil shale comprises: feeding raw oil shale into a heated retorting unit, to convert kerogen into a retorted stream; introducing the retorted stream to a distillation column to generate a high-cetane diesel stream, an α-olefin-containing chemical stream, an asphalt/asphalt additive stream, and an overhead gas stream, wherein heat contained in the retorted stream is harnessed as distillation energy; separating the overhead gas stream into a fuel gas stream and a purge gas stream; combusting the fuel gas stream to generate hot flue gas; heating the purge gas with hot flue gas; feeding the heated purge gas directly to the heated retorting unit; and recovering the high-cetane diesel stream, the α-olefin-containing chemical stream, and the asphalt/asphalt additive stream as products.
