A fluid system includes an inlet conduit disposed in a fluid flow path between a fluid source and a fluid destination. The fluid conduit includes a fluid mixing portion. The fluid system includes a fluid separation module disposed in the flow path downstream of the constriction between the source and the destination. The fluid separation module includes a first fluid separator. The fluid system includes a second fluid separator disposed in the flow path upstream of the first fluid separator. The fluid system includes a feedback conduit that may provide fluid communication between an outlet of the fluid separation module and the fluid mixing portion.

A dip-conduit purification apparatus (102) comprises a purification line comprising a plurality of serially coupled purification conduits (124, 126, 128), each of the plurality of purification conduits (124, 126, 128) having an inlet at a first distal end thereof in fluid communication with an outlet at a second distal end thereof.

The present disclosure provides a method for generating higher hydrocarbon(s) from a stream comprising compounds with two or more carbon atoms (C.sub.2+), comprising introducing methane and an oxidant (e.g., O.sub.2) into an oxidative coupling of methane (OCM) reactor. The OCM reactor reacts the methane with the oxidant to generate a first product stream comprising the C.sub.2+ compounds. The first product stream can then be directed to a separations unit that recovers at least a portion of the C.sub.2+ compounds from the first product stream to yield a second product stream comprising the at least the portion of the C.sub.2+ compounds.

In general, the present invention is directed to processes for separating a vapor comprising a first component and a second component using high-pressure density-driven separation. The present invention further relates to various processes for the capture of carbon dioxide. In particular, various processes of the present invention relate to the separation of carbon dioxide from flue gas of combustion processes. The invention also applies to upgrading fuel gases containing carbon dioxide. The invention also applies to separation of hydrogen from fuel gas vapor solutions.

The present invention relates to a novel integrated system for providing nitrogen (N2) to a variety of industrial service applications such as, for example, process unit drying, pipeline purging, reactor cooling, vessel inerting, pipeline displacement.

An ammonia manufacturing apparatus includes: an ammonia synthesis unit synthesizing ammonia under a chemical reaction using hydrogen and nitrogen as a raw material gas in a reactor; and a heat storage unit including a heating medium. The heat storage unit can supply heat from the heating medium to the ammonia synthesis unit when an amount of the raw material gas supplied to the ammonia synthesis unit increases.

Systems and processes for use of concentric adsorbent beds with rotary valve assemblies are provided.

A separation membrane structure comprises a porous support, and a separation membrane formed on the porous support. The separation membrane has an average pore diameter of greater than or equal to 0.32 nm and less than or equal to 0.44 nm. The separation membrane includes addition of at least one of a metal cation or a metal complex that tends to adsorb nitrogen in comparison to methane.

A system for harvesting nitrogen, comprising a motored robotic litter processing vehicle including an elongate housing creating an inner space for mounting components. A nitrogen harvester box connected to a rear portion of the vehicle is provided including a vacuum canopy connecting four sides to a floor, and wheels. A scoop level to ground having an opening facing the vehicle is enabled to collect litter material including nitrogen. A sieve screen having a mesh size positioned laterally at a height above the floor enables nitrogen particles smaller than the mesh size to fall through the sieve and nitrogen particles larger than the mesh size to be captured on a top surface of the sieve, wherein a vacuum chute collects the particles smaller than the mesh size and deposits them into a collection bin.

A system for recovering nitrogen during regeneration of a treater, the system including an adsorbent bed downstream of the treater, wherein the adsorbent bed comprises an adsorbent operable to adsorb at least one impurity from a treater bed regeneration effluent stream comprising nitrogen to provide a nitrogen product having a higher nitrogen purity than a nitrogen purity of the treater bed regeneration effluent stream. A method for recovering nitrogen during regeneration of a treater is also provided.
