Abstract: The present disclosure provides natural gas and petrochemical processing systems, including oxidative coupling of methane reactor systems that may integrate process inputs and outputs to cooperatively utilize different inputs and outputs in the production of higher hydrocarbons from natural gas and other hydrocarbon feedstocks. The present disclosure also provides apparatuses and methods for heat exchange, such as an apparatus that can perform boiling and steam super-heating in separate chambers in order to reach a target outlet temperature that is relatively constant as the apparatus becomes fouled. A system of the present disclosure may include an oxidative coupling of methane (OCM) subsystem that generates a product stream comprising compounds with two or more carbon atoms, and a dual compartment heat exchanger downstream of, and fluidically coupled to, the OCM subsystem.

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.

Abstract: Process for the partial oxidation of a liquid or solid and/or a gaseous fuel using a multi-orifice burner comprising a central channel and four concentric channels encircling the central channel. Liquid or solid fuel is supplied through the second concentric channel and the oxidizer is supplied through the first concentric channel and the third concentric channel. Hydrocarbon gas and/or moderator is supplied through the central channel and the fourth concentric channel. The mass ratio of liquid or solid fuel to hydrocarbon gas ranges from 0 to 1.

Abstract: A protruding mantle separates burner internals from the hot gasification environment. The mantle is cooled by at least one of the feedstreams. The lining can be made of ceramics such as silicon carbide and/or silicon nitride. In order to lower thermo-mechanical stress the lining is thin-walled.
