    摘要： A typical rotary face seal employs a seal ring rotating relative to a sealing surface and also employs means to urge the seal ring towards the sealing surface in order to effect a seal. The seal ring may itself comprise a seal face bonded to a backing ring. In certain applications, the seal face may deform significantly as a result of the temperature variations experienced and an undesirable crowning of the seal face may occur. Such crowning may be reduced by employing an improved seal ring with anti-crowning features in which the thickness of an edge of the seal face is different from that in the middle of the seal face, or in which a relief slot is employed in the seal face. The improved seal ring is particularly suited for rotary face seals used in a rotary valve in a rotary gas separation device.

    摘要： A chemical reaction is performed with separation of the product(s) and reactant(s) by pressure swing adsorption (PSA), using an apparatus having a plurality of adsorbers cooperating with first and second valve assemblies in a PSA module. The PSA cycle is characterized by multiple intermediate pressure levels between higher and lower pressure 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, entering from compressor stage(s) or exiting into exhauster or expander stages, under substantially steady conditions of flow and pressure. The PSA module comprises a rotor containing the 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. The reaction may be performed within a portion of the rotor containing a catalyst.

    摘要： A pressure swing adsorption system for separating components of a gas mixture includes a first adsorbent module, and a second a adsorbent module coupled to the a first adsorbent module. 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： Pressure swing adsorption separation of a feed gas mixture, to obtain a purified product gas of the less strongly adsorbed fraction of the feed gas mixture, is performed with a cooperating set of "N" adsorbers in a rotary assembly, with each adsorber communicating at its product end directly to a rotary cyclic displacement chamber, and at its feed end by rotary distributor valve ports to a rotary piston feed compressor and a rotary piston exhaust vacuum pump. The compressor and vacuum pump are integrated with the cycle, and rotate at "N" times the cycle frequency. Alternative adsorber configurations for high frequency operation are disclosed.

    摘要： Pressure swing adsorption separation of a gas mixture is performed in an apparatus with a plurality of adsorbent beds cooperating to exchange energy from an adsorbent bed undergoing a depressurization step to an adsorbent bed undergoing a pressurization step, and with provision for thermal coupling in order to improve process efficiency. Thermal coupling is provided as heating to augment expansion energy recovery, and as a temperature gradient imposed in adsorbent beds to provide the function of a thermal regenerator in a regenerative thermodynamic cycle. The invention provides improved techniques for recovery of expansion energy in pressure swing adsorption, and for direct application of thermal energy to power pressure swing adsorption processes.
