  • Publication number: 20180100845
    Abstract: 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.

  • Publication number: 20180079975
    Abstract: 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.

  • Patent number: 9861910
    Abstract: A process and system for improving the efficiency of regenerating a CO2-rich liquid absorbent stream following contact in an absorption zone with, e.g., a flue gas stream from which it has absorbed CO2, 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°-85° C. for aqueous K2CO3 sorbent, 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 CO2 from the liquid sorbent from which it has been released.

  • Publication number: 20170233665
    Abstract: 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.
