Abstract: A device for mixing two gas streams, the device includes: an inner pipe, wherein: the inner pipe is arranged substantially concentrically within an outer pipe and forms an annulus between an outer diameter of the inner pipe and an inner diameter of the outside pipe; the inner pipe is closed at a downstream end; and the inner pipe comprises a plurality of perforations; and the outer pipe, wherein: a downstream end of the outer pipe extends into a reactor; the outer pipe is closed at the downstream end; and the downstream end of the outer pipe comprises a plurality of perforations. The mixed gas stream can enter the reactor. The reactor can be an Oxidative Coupling of Methane (OCM) reactor.

Abstract: An electrically powered furnace and related methods may include an electrically powered furnace having an output of at least one megawatt with a control system; a furnace housing comprising one or more housing walls at least partially defining an interior volume; a plurality of heating zones within the interior volume; and a plurality of heated tubes extending in the interior volume. A method may include providing the feed to the electrically powered furnace; and algorithmically adjusting the output of the one or more heating elements for each of the plurality of heating zones to heat the feed to a desired temperature while maintaining temperatures of the one or more heating elements within predetermined parameters.
