    Abstract: A methane conversion process for producing C2+ hydrocarbons comprising (a) introducing a reactant mixture comprising methane (>20 mol %) and an inert compound to a reaction unit to produce a reactor effluent stream comprising C2+ hydrocarbons, methane, the inert compound, and water and/or carbon dioxide; (b) removing at least a portion of the water and/or at least a portion of the carbon dioxide from the reactor effluent stream to produce a demethanizer feed stream; (c) feeding at least a portion of the demethanizer feed stream to a demethanizer unit to produce two or more vapor streams (methane rich stream and inert rich stream), and at least one liquid stream (C2+ hydrocarbons); (d) withdrawing at least a portion of the inert rich stream as a purge stream; (e) recycling any remaining portion of the inert rich stream to the reaction unit; and (f) recycling the methane rich stream to the reaction unit.

    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 oxidative methane coupling (OCM) reactor has a reactor vessel that defines a reactor vessel interior. The reactor vessel having opposite ends and a central longitudinal axis that extends between the opposite ends. A catalyst bed assembly is positioned within the reactor vessel interior having a catalyst bed containing a layer of OCM catalyst of a uniform thickness. The catalyst bed assembly divides the reactor vessel interior into an upstream zone and a downstream zone. The catalyst bed has an upstream face for receiving the one or more flowing feed gases of methane and oxygen gas as a flowing mixture from the upstream zone. The upstream face of the catalyst bed is configured to have a total area that exceeds the largest transverse cross-sectional area of the interior of the reactor vessel that is perpendicular to the central longitudinal axis of the reactor vessel. The catalyst bed assembly is configured so that any portion of the flowing mixture passes from the upstream zone to the downstream zone through a single catalyst bed of the catalyst bed assembly.
