  • Process for producing olefins using aromatic saturation
    Patent number: 11001772
    Abstract: A process for increasing olefin production from refinery that processes hydrocarbon streams that are rich in aromatic compounds and includes steam cracking and hydrotreating an aromatically rich feedstock to produce a hydrotreated pyrolysis gasoline stream and light pyrolysis oil byproduct, saturating at least one additional naphtha/hydrocarbon stream together with the hydrotreated pyrolysis gasoline stream or together with the light pyrolysis oil byproducts to form a first naphthene stream, and steam cracking the first naphthene stream to produce olefins.
    Type: Grant
    Filed: February 9, 2017
    Date of Patent: May 11, 2021
    Assignee: SABIC GLOBAL TECHNOLOGIES B.V.
