An hydroconverted effluent composition is provided, along with systems and methods for making such a composition. The hydroconverted effluent composition can have an unexpectedly high percentage of vacuum gas oil boiling range components while having a reduce or minimized amount of components boiling above 593° C. (1100° F.). In some aspects, based in part on the hydroprocessing used to form the hydroconverted effluent composition, the composition can include unexpectedly high contents of nitrogen. Still other unexpected features of the composition can include, but are not limited to, an unexpectedly high nitrogen content in the naphtha fraction; and an unexpected vacuum gas oil fraction including an unexpectedly high content of polynuclear aromatics, an unexpectedly high content of waxy, paraffinic compounds, and/or an unexpectedly high content of n-pentane asphaltenes

The present application provides a method and a system for recycling a polymer. The method includes introducing polymer into a primary melting extruder, producing a polymer melt that is combined with a fluid oil to at least partially dissolve the polymer melt. A secondary mixing extruder mixes these to form a polymer solution that is introduced into a refinery oil stream, producing a polymer-comprising oil stream, which is fed into a refinery process unit. The system includes a primary melting extruder for forming a polymer melt from polymer. A secondary mixing extruder receives the polymer melt. One or more hydrocarbon inflow conduits for providing a fluid oil to the primary melting extruder and/or the secondary mixing extruder are configured to form a polymer solution from the fluid oil and the polymer melt. There is a feed system outlet for feeding the polymer solution to a refinery oil stream.

Method of refining whole crude oil or a wide cut crude oil, the methods comprising a combination of a hydrotreating reactor, a distillation tower, and an optional flash evaporation separator. The methods can also include light ends processing, fluid catalytic cracking, reforming, hydrocracking, and demetalization. In some methods a whole crude oil is first processed through a flash evaporation separator to create a wide cut crude oil and in other methods, the flash evaporation separator is not used as the whole crude oil is first treated in a hydrotreater.

Method for driving machines, in an ethylene plant steam generation circuit, the method including recovering heat as high pressure steam from a cracking furnace; providing said high pressure steam to at least one steam turbine, wherein the steam turbine is configured to drive a machine, such as a process compressor; condensing at least part of the high pressure steam in a condenser; pumping condensed steam as boiler feed water back to the cracking furnace.

The present invention addresses to a hydrothermal liquefaction process capable of generating a liquid stream, rich in renewable molecules, with lower oxygen content, lower percentage of water and lower acidity compared to other products of thermochemical processes of biomass conversion. In order to effectively carry out this process, a catalyst was developed, obtained from the calcination of castor bean hull, to be used in the field of biofuels in order to provide an environmentally friendly alternative for the production of fuels.

Saturation of a pyrolysis stream is achieved while managing exotherms. The pyrolysis stream is split into at least two feed streams for at least two saturation reactors. The process may split the hydrogen stream into at least two streams for the at least two saturation reactors. A recycle stream may also be provided to manage the exotherm. The feed may comprise at least 5 wt % aromatics.

The present invention relates to a process and system for complete conversion of crude oils by integrating Desalter unit, Atmospheric and vacuum column, high severity FCC process, Naphtha cracking process, residue slurry hydrocracking process, Delayed coking process, Selective mild hydrocracking aromatic production unit, Dehydrogenation units, Aromatic/olefin recovery section, gasifier unit along with syngas to olefins conversion section.

The present invention relates to an NCC process and an apparatus for producing light olefins and aromatics, wherein the fraction comprising ethane and/or propane (12) from the cracking effluent is sent at least partly into a steam cracking furnace (19), fed with steam (20), to produce a steam cracking effluent (21) comprising ethylene and/or propylene.

Provided is a method for upgrading a bio-based material, the method including the steps of pre-treating bio-renewable oil(s) and/or fat(s) to provide a bio-based fresh feed material, hydrotreating the bio-based fresh feed material, followed by separation, to provide a bio-propane composition.

Aqueous wastewater from hydrothermal liquefaction (HTL) systems is typically high in chemical oxygen demand (COD), which renders classic aerobic wastewater treatment to be prohibitively expensive. HTL wastewater can be processed using thermochemical wet oxidation in a manner that is not only cost efficient but also contributes more heat than is required for the energetically demanding HTL process. Provided are methods and devices for integrated hydrothermal liquefaction of biomass and treatment of resulting wastewater.
