  • Publication number: 20210139391
    Abstract: The present disclosure provides petrochemical processing methods and systems, including ethylene conversion processes and systems, for the production of higher hydrocarbon compositions, for example liquid hydrocarbon compounds, with reduced amount of unsaturated hydrocarbons.
    Type: Application

  • Publication number: 20210139392
    Abstract: The present disclosure provides systems and methods for producing olefins via an oxidative coupling of methane (OCM) process. The systems and methods may comprise the use of a staged process comprising at least one non-adiabatic section that is in thermal communication with a heat transfer medium and at least one substantially adiabatic section. The systems and methods may also comprise the use of a diluent stream which may improve methane conversion in an OCM reactor and an ethylene/ethane ratio in a post-bed cracking unit. The methods and systems may further comprise injecting oxygen (O2) and a paraffin into a gas stream containing a radical transfer agent to provide a reaction mixture. The reaction mixture may be held in a vessel for a time period greater than an auto-ignition delay time (AIDT), such that the reaction mixture may ignite to liberate heat and convert to a product mixture comprising olefins.
