A method may include: introducing a fluid comprising a first immiscible phase and a second immiscible phase into a contacting vessel comprising multiple contact stages: flowing the fluid through a first fiber bundle disposed in the contacting vessel; separating at least a portion of the first immiscible phase from the second immiscible phase; and flowing the separated portion of the first immiscible phase through a second fiber bundle disposed in the contacting vessel.

Multi-stage contacting process and apparatus

An improved contactor/separator process is presented where one or more stages of contact and separation is achieved by providing one or more shroud and disengagement device combinations within a vessel, where the disengagement device is connected to the top of the shroud that contains vertically hanging fibers. A liquid admixture of immiscible fluids is directed co-currently upward through the shroud at flooding velocity or greater, where all of the admixture exits the disengagement device through a coalescing material. Tray supports are used to stack additional shroud and disengagement combinations vertically within the vessel. Each tray allows less dense liquids exiting one disengagement device from a lower shroud and disengagement device combination to enter the bottom of a shroud of a shroud and disengagement device combination position vertically above the lower shroud and disengagement device combination.

Contactor and separation apparatus and process of using same

In an improved fiber-film type contactor/separator an enhanced coalescing zone is provided by the presence of a disengagement device connected to a shroud that contains a bundle of high surface area vertical hanging fibers, where the enhanced coalescing zone diverts a portion of an admixture of immiscible liquids to flow radially in a path not parallel to the vertical axis of the hanging fibers whereby the diverted portion of liquids contacts a coalescing surface to cause at least one of the liquids to coalesce into droplets. The immiscible liquids are allowed to settle into separate phase layers and first and second outlets selectively remove the higher density liquid from the lower density liquid.

The recovery of solids, and particularly solid particulates used as catalysts in slurry hydroprocessing, from asphaltene containing hydrocarbons is improved by controlling asphaltene precipitation. The formation of agglomerates of the solid particulates, having an increased diameter, results in the presence of precipitated asphaltenes, possibly due to flocculation. Asphaltene precipitation is controlled by varying process parameters or introducing additional diluent or flush streams that change the polarity of an asphaltene containing liquid product recovered from an effluent of a slurry hydroprocessing reaction zone.

Solids management in slurry hydroprocessing

Slurry hydrocracking a heavy hydrocarbon feed produces a HVGO stream and a pitch stream. At least a portion of the pitch stream is subjected to SDA to prepare a DAO stream low in metals. The DAO is blended with at least a portion of the HVGO stream to provide turbine or marine fuel with acceptable properties for combustion in gas turbines or for marine fuel grades.

Process for producing hydrocarbon fuel

One exemplary embodiment can be a process for making a catalyst including an effective amount of iron for catalyzing one or more reactions in a hydrocarbon conversion system. The process can include grinding and coating the particles. The ground particles can have an effective amount of iron, and substantially all the particles may have a maximum dimension no larger than about 130 microns. The coating can have an effective amount of one or more hydrocarbons to provide the catalyst with improved flowability.

Hydrocarbon conversion system, and a process and catalyst composition relating thereto

An integrated unit operations for the treatment of a waste stream, such as spent caustic, is provided in a single vertical vessel having at least three separate zones: a mixing, a settling, and a mass transfer zone.

Apparatus for treating a waste stream

A process for improving flow properties of crude may include processing a first crude stream, which may in turn include cracking the first crude stream with fresh catalyst to form a cracked stream and spent catalyst, and then mixed with an unprocessed second stream. The spent catalyst may be regenerated to form fresh catalyst, which may then be recycled. At least part of the cracked stream may be mixed with a second crude stream. A ratio of the second crude stream to the first crude stream may be between about 0.5:1 and about 9:1. A ratio of part of the cracked stream to add to the second crude stream may be selected to achieve a API gravity of at least about 18. The first crude stream may be heated and stripped before being cracked.

Process and apparatus for improving flow properties of crude petroleum

A process is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a particulate solid material to form a heavy hydrocarbon slurry and hydrocracked in a slurry hydrocracking unit to produce vacuum gas oil (VGO) and pitch. A first vacuum column separates VGO from pitch, and a second vacuum column further separates VGO from pitch. As much as 15 wt-% of VGO can be recovered by the second vacuum column and recycled to the slurry hydrocracking unit. A pitch composition is obtained which can be made into particles and transported without sticking together.
