The first adsorbent module includes a first gas inlet for receiving the gas mixture, at least one bed of first adsorbent material in communication with the first gas inlet for adsorbing a gas mixture component from the gas mixture, and a first gas outlet in communication with the first adsorbent beds for receiving a first product gas therefrom. The second adsorbent module includes a second gas inlet coupled to the first gas outlet for receiving the first product gas, at least one second bed of adsorbent material in communication with the second gas inlet for adsorbing a first product gas component from the first product gas, and a second gas outlet in communication with the second adsorbent beds for receiving a second product gas therefrom. The first product gas substantially excludes the adsorbed gas mixture component, and the second product gas substantially excludes the adsorbed first product gas component. Also, the adsorbent modules are configured for transferring the first product gas between the adsorbent modules over a plurality of discrete pressure levels to maintain substantial uniformity of gas flow therebetween.

摘要： Gas separation by pressure swing adsorption (PSA) is performed within an apparatus having a plurality of adsorbers cooperating with first and second valves in a rotary PSA module, with the PSA cycle characterized by multiple intermediate pressure levels between the higher and lower pressures of the PSA cycle. Gas flows enter or exit the PSA module at the intermediate pressure levels as well as the higher and lower pressure levels, under substantially steady conditions of flow and pressure. The PSA module comprises a rotor containing laminated sheet adsorbers and rotating within a stator, with ported valve faces between the rotor and stator to control the timing of the flows entering or exiting the adsorbers in the rotor.

摘要： Disclosed embodiments of the apparatus address the challenges of rotary PSA systems, both axial and radial flow, with M>1 by providing interpenetrating, layered manifolds to accommodate all of the steps of a complex PSA cycle, suitable with equal compactness for any value of nullMnull. This approach extends readily to accommodate a plurality of rotary PSA modules and their cooperating compression machinery within a single layered manifold assembly for a single PSA plant train. Described embodiments of the rotary PSA apparatus include stators that define fluid ports. In particular embodiments of the described apparatus, a second stator defines pressure swing adsorption cycle sectors, each sector being defined by a light product delivery port, light product withdrawal ports, and light reflux return ports. The adsorber elements may directly contact one or more of the stators in a fluidly sealing manner (i.e., have a clearance gap of from about 0 to about 50 microns) using described reinforced adsorbers. The method comprises providing an embodiment of the described apparatus and then supplying at least one feed fluid to pressurize an adsorber element of the adsorber sets to substantially a higher pressure to initiate a pressure swing adsorption cycle.

摘要： The present invention relates to a rotary valve assembly for a pressure swing adsorption system. The rotary valve assembly includes a first valve member and a second valve member relatively rotatable about a common center of rotation to provide valving action for selectively transferring fluids therethrough. The second valve member has a first fluid section with at least one aperture adapted for transferring a first fluid of a first pressure and composition therethrough and a second fluid section with at least one aperture adapted for transferring a second fluid of a second pressure and composition therethrough. The first valve member has a first fluid section with at least one passage for transferring the first fluid in the valve assembly and a second fluid section with at least one passage for transferring the second fluid in the valve assembly. A vent is located between the first fluid sections and the second fluid sections of the valve assembly and is vented to a pressure lower than the pressures of the first and second fluids so as to vent leakage from either of the sections of the valve assembly. The rotary valve assembly further includes means for effecting relative rotation of the first valve member and second valve member.

摘要： A rotary valve assembly which includes of a pair of valve parts with flat faces which, when pressed together and rotated, provide valving action between various ports incorporated in one of the valve parts. The first valve part contains two circular arrays of through openings, each of which is connected to a conduit. The second valve part contains several passages which provide communication between various openings of the first valve part and valve ports located in the second valve part. The second valve part also contains one or more passages which provide communication between two openings of one array of openings and one opening of the other array of openings. The valve assembly can be effectively used to automate operation of a gas or liquid adsorption system comprising two or more adsorption vessels, the number of vessels being equivalent to the total number of openings in either array. Use of the valve assembly in an adsorption system eliminates the need for many of the valves required in conventional multivessel adsorption systems.

摘要： A high pressure as stream having a hydrogen content of up to about 90 mol percent is passed to a separator containing a permeable membrane capable of selectively permeating hydrogen. The separator is used to achieve a bulk separation of the desired hydrogen from impurities contained in the gas stream. The separated hydrogen is recovered at a reduced pressure and is passed to a pressure swing adsorption system adapted for operation at said reduced pressure. The off-gas from the separator is recovered essentially at the higher pressure of the gas stream. A portion of the off-gas is throttled to a lower pressure, with appropriate power recovery, and is passed to the pressure swing adsorption system as a co-feed gas, thereby contributing to the recovery of purified hydrogen product and to a reduction in the operating costs for the desired hydrogen separation and purification. The remaining off-gas is recovered as a relatively high pressure fuel or feed gas for other purposes.
