Process and apparatus for producing helium, neon, or argon product gas using an adsorption separation unit having minimal dead end volumes. A purification unit receives a stream enriched in helium, neon, or argon, and a stream is recycled from the purification unit back to the adsorption separation unit in a controlled manner to maintain the concentration of the helium, neon, or argon in the feed to the separation unit within a targeted range.

Separation process and apparatus for light noble gas

Disclosed herein are rapid cycle pressure swing adsorption (PSA) process for separating Ofrom Nand/or Ar. The processes use a carbon molecular sieve (CMS) adsorbent having an O/Nand/or O/Ar kinetic selectivity of at least 5 and an Oadsorption rate (1/s) of at least 0.2000 as determined by linear driving force model at 1 atma and 86&#xb0; F.

Carbon molecular sieve adsorbent

Disclosed herein are multi-bed rapid cycle pressure swing adsorption (RCPSA) processes for separating Ofrom Nand/or Ar, wherein the process utilizes at least five adsorption beds each comprising a kinetically selective adsorbent for Ohaving an Oadsorption rate (1/s) of at least 0.20 as determined by linear driving force model at 1 atma and 86&#xb0; F.

Multi-bed rapid cycle kinetic PSA

Disclosed herein is a stator plate for a rotary bed PSA apparatus that has an exhaust slot that has first and second sections for receiving blowdown and purge exhaust gas streams, the sections being separated by a flow restriction that restricts but does not full prevent gas flow between the sections, or that has separate exhaust slots for separately receiving the blowdown and purge exhaust gas streams. Also disclosed is pressure swing adsorption (PSA) apparatus including such a stator plate, and a rotary bed PSA process using such an apparatus.

Port separation for rotary bed PSA

Disclosed are novel, as-crystallized RHO zeolite compositions with improved uniformity in morphology. These RHO compositions are useful for preparing cation-exchanged RHO zeolites that can be used as adsorbents for oxygen and/or nitrogen with improved properties. The adsorbents can be used in pressure swing adsorption processes for selectively adsorbing oxygen and/or nitrogen from feed streams such as an air stream or crude argon stream. Also disclosed are novel methods of preparing RHO zeolites with improved morphology control.

RHO zeolites and method of making the same

Disclosed herein are novel RHO zeolites useful as kinetically selective adsorbents for oxygen and/or nitrogen. The adsorbents can be used in pressure swing adsorption processes for selectively adsorbing oxygen and/or nitrogen from feed streams such as an air stream or crude argon stream. Also disclosed are novel methods of preparing RHO zeolites, including in particular mixed-cation RHO zeolites.

RHO adsorbent compositions, methods of making and using them

Disclosed herein are new processes for adsorbing oxygen using adsorbent compositions comprising RHO zeolites kinetically selective for oxygen. The RHO zeolites can be used in pressure swing adsorption processes for separating oxygen from oxygen containing streams, such as for, but not limited to, purifying a crude argon feed stream or separating oxygen from an air feed stream.

Processes using improved RHO adsorbent compositions

An adsorbent having a composition comprising at least 90% chabazite where the chabazite is a single phase chabazite having an Si/Al ratio of 1.2 to 1.8, the chabazite includes a mixture of at least two types of cations, and each of the at least two types of cations are in a molar ratio relative to Al of at least 0.05.

Modified chabazite adsorbent compositions, methods of making and using them

Methods and systems for purifying argon from a crude argon stream are disclosed, employing pressure swing adsorption at cold temperatures from &#x2212;186&#xb0; C. to &#x2212;20&#xb0; C.; more preferably from &#x2212;150&#xb0; C. to &#x2212;50&#xb0; C.; and most preferably from &#x2212;130&#xb0; C. to &#x2212;80&#xb0; C. with oxygen-selective zeolite adsorbent. In some embodiments, the oxygen-selective zeolite adsorbent is a 4A zeolite, a chabazite, or a combination thereof.

Method for argon production via cold pressure swing adsorption

A method of separating oxygen from an oxygen-containing fluid stream is disclosed, the method including the step of contacting the oxygen-containing fluid stream with an oxygen-selective zeolite adsorbent comprising at least 90% chabazite, wherein the chabazite is a single phase chabazite having an Si/Al ratio of 1.2 to 1.8. The single phase chabazite may comprise a mixture of at least two types of cations.

Pressure swing adsorption system comprising two or more vessels, each having a feed end, a product end, and adsorbent material adapted to adsorb one or more components from a multi-component feed gas mixture; piping adapted to (1) introduce the feed gas mixture into the feed ends, withdraw a product gas from the product ends, and withdraw a waste gas from the feed ends of the vessels, and (2) place the product ends of any pair of vessels in flow communication; a feed pipe adapted to supply the feed gas mixture to the system; a product pipe adapted to withdraw the product gas from the system; and a waste gas pipe adapted to withdraw the waste gas from the system. An indexed rotatable multi-port valve is adapted to place the product end of each vessel in sequential flow communication with the product end of each of the other vessels.
