Processes herein may be used to thermally crack various hydrocarbon feeds, and may eliminate the refinery altogether while making the crude to chemicals process very flexible in terms of crude. In embodiments herein, crude is progressively separated into at least light and heavy fractions. Depending on the quality of the light and heavy fractions, these are routed to one of three upgrading operations, including a fixed bed hydroconversion unit, a fluidized catalytic conversion unit, or a residue hydrocracking unit that may utilize an ebullated bed reactor. Products from the upgrading operations may be used as feed to a steam cracker.

Configuration for olefins production

A process for steam cracking a whole crude including a volatilization step performed to maintain a relatively large hydrocarbon droplet size. The process may include contacting a whole crude with steam to volatilize a portion of the hydrocarbons, wherein the contacting of the hydrocarbon feedstock and steam is conducted at an initial relative velocity of less than 30 m/s, for example. The resulting vapor phase, including volatilized hydrocarbons and steam may then be separated from a liquid phase comprising unvaporized hydrocarbons. The hydrocarbons in the vapor phase may then be forwarded to a steam pyrolysis reactor for steam cracking of the hydrocarbons in the vapor phase.

Process for mixing dilution steam with liquid hydrocarbons before steam cracking

A process is provided that is directed to integrated steam pyrolysis and hydroprocessing including residual bypass to permit direct processing of crude oil feedstocks to produce petrochemicals including olefins and aromatics.

Integrated hydrotreating and steam pyrolysis process including residual bypass for direct processing of a crude oil

A system is provided that is directed to a steam pyrolysis zone integrated with a hydroprocessing zone including residual bypass to permit direct processing of crude oil feedstocks to produce petrochemicals including olefins and aromatics.

Integrated hydrotreating and steam pyrolysis system including residual bypass for direct processing of a crude oil

Steam pyrolysis and hydroprocessing are integrated including hydrogen redistribution to permit direct processing of crude oil feedstocks to produce petrochemicals including olefins and aromatics. A feed is initially split into a light portion and a heavy portion, and the heavy portion is hydroprocessed. A hydroprocessed effluent is charged, along with steam, to a convection section of a steam pyrolysis zone. The mixture is heated and passed to a vapor-liquid separation section. A residual portion is removed and light components are charged to a pyrolysis section of the steam pyrolysis zone. A mixed product stream is recovered from the steam pyrolysis zone and it is separated into product including olefins and aromatics.

Integrated solvent deasphalting and steam pyrolysis system for direct processing of a crude oil

An integrated hydrotreating and steam pyrolysis system for the direct processing of a crude oil is provided to produce olefinic and aromatic petrochemicals. Crude oil and hydrogen are charged to a hydroprocessing zone operating under conditions effective to produce a hydroprocessed effluent reduced having a reduced content of contaminants, an increased paraffinicity, reduced Bureau of Mines Correlation Index, and an increased American Petroleum Institute gravity. Hydroprocessed effluent is thermally cracked in the presence of steam to produce a mixed product stream, which is separated. Hydrogen from the mixed product stream is purified and recycled to the hydroprocessing zone, and olefins and aromatics are recovered from the separated mixed product stream.

An integrated slurry hydroprocessing and steam pyrolosyis system for the production of olefins and aromatic petrochemicals from a crude oil feedstock is provided. Crude oil, a steam pyrolysis residual liquid fraction and slurry reside are combined and treated in a hydroprocessing zone in the presence of hydrogen under conditions effective to produce an effluent having an increased hydrogen content. The effluent is thermally cracked with steam under conditions effective to produce a mixed product stream and steam pyrolysis residual liquid fraction. The mixed product stream is separated and olefins and aromatics are recovered and hydrogen is purified and recycled.

Integrated slurry hydroprocessing and steam pyrolysis of crude oil to produce petrochemicals

The present invention relates to a method and apparatus for determining trace amounts of water in oil, including the steps of obtaining a blended sample of a low water content fluid including an amount of water and an amount of oil, transferring a portion of the blended sample to a cuvette to create a measurement sample, covering a viewing surface of the cuvette with an opaque sheet with a slit, providing a barrier with a fixed opening between a laser source and a laser-receptive surface of the cuvette, transmitting a pulsed laser beam from the laser source into the cuvette; inducing fluorescence in the measurement sample, focusing the fluorescence through a collecting lens and transmitting the fluorescence to a spectrometer, and measuring the fluorescence with the spectrometer by dispersing the fluorescence with a spectrograph and intensifying the fluorescence with an intensified charge coupled device.

Method for non-intrusive measurement of low water content in oil

A process and system for improving the efficiency of regenerating a CO-rich liquid absorbent stream following contact in an absorption zone with, e.g., a flue gas stream from which it has absorbed CO, and recovering a substantially pure stream of includes passing the pressurized liquid sorbent through a heating zone to heat it to the desorption temperature, e.g., to about 80&#xb0;-85&#xb0; C. for aqueous KCOsorbent, introducing the heated liquid sorbent into a cyclone separation zone where the combination of increased temperature, reduced pressure and the centrifugal forces on the liquid/gas mixture result in a relatively more rapid and efficient separation of the COfrom the liquid sorbent from which it has been released. The CO-lean liquid sorbent descends to the bottom of the cyclone separator and is recovered, cooled and recycled to the absorption zone; the COwithdrawn from the cyclone separation zone passes through a condenser to remove moisture and any other condensates present, and the COis recovered for storage or use in downstream processes.

The effluent is thermally cracked with steam under conditions effective to produce a mixed product stream and steam pyrolysis residual liquid fraction.
