  • Publication number: 20160244681
    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: 9096806
    Abstract: An integrated hydroprocessing and fluid catalytic cracking process is provided for the direct processing of a crude oil 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 having a reduced content of contaminants, an increased paraffinicity, reduced Bureau of Mines Correlation Index, and an increased American Petroleum Institute gravity. The hydroprocessed effluent is separated into a low boiling fraction and a high boiling fraction. The low boiling fraction is cracked in a first downflow reactor of a fluid catalytic cracking unit in the presence of a predetermined amount of catalyst to produce cracked products and spent catalyst, and the high boiling fraction is cracked in a second downflow reactor of the fluid catalytic cracking unit in the presence of a predetermined amount of catalyst to produce cracked products and spent catalyst.

  • Publication number: 20150152027
    Abstract: The process described herein broadly comprehends an integrated process that permits the use of straight run residual fractions as a feedstock to produce lighter olefins including propylene. A blend of natural gas condensate and/or naphtha, and heavy oil residue(s), is catalytically cracked to produce a light olefin-rich product stream. In particular, the light natural gas condensate and/or naphtha stream is used as both solvent in a solvent-deasphalting unit and a portion for the feedstock to a fluidized catalytic cracking process. In addition, blending a heavy boiling hydrocarbon stream with a light natural gas condensate or naphtha stream enables efficient cracking in fluidized catalytic cracking process processes while sustaining the heat balance within the cracking unit.
