  • Publication number: 20210348850
    Abstract: A coil-wound heat exchanger with mixed refrigerant shell side cooling that is adapted to reduce radial temperature maldistribution by providing tube sheets at one end of a warm bundle that are each connected to tube sheets in a single circumferential zone and are in fluid flow communication with a control valve. Tube sheets at the other end of the warm bundle are each connected to tube sheets in a single radial section and in multiple circumferential zones. A temperature sensor is provided in each circumferential zone. When a temperature difference is detected, one or more of the control valves is adjusted to reduce the temperature difference.

  • Patent number: 8529674
    Abstract: Pressure swing adsorption process for the separation of a feed gas mixture comprising (a) providing a pressure swing adsorption system comprising one or more composite beds, each composite bed comprising adsorbent material disposed in two or more vessels in parallel flow configuration, each vessel having a feed end and a product end; (b) performing cyclic sequential steps comprising adsorption/make product, withdrawing gas at decreasing pressure from the composite bed, purging the composite bed, and introducing gas into the composite bed at increasing pressure; and (c) for any of the sequential steps, setting a flow rate or flow rates of one or more gases selected from the group consisting of gas introduced into or withdrawn from the feed end or ends of any of the two or more vessels and gas introduced into or withdrawn from the product end or ends of any of the two or more vessels.

  • Patent number: 7501009
    Abstract: A method and apparatus for producing high purity argon by combined cryogenic distillation and adsorption technologies is disclosed. Crude argon from a distillation column or a so-called argon column is passed to a system of adsorption vessels for further purification. Depressurization gas from adsorption is introduced back, in a controlled manner, to the distillation column and/or a compressor or other means for increasing pressure. Particulate filtration and getter purification may optionally be used.

  • Patent number: 6709486
    Abstract: A pressure swing adsorption process for recovering a less readily adsorbable component from a feed gas mixture comprising at least one less readily adsorbable component and at least one more readily adsorbable component. The process utilizes a plurality of adsorbent beds, each bed having a feed end and product end, wherein the process includes the gas transfer steps of (1) transferring gas from the product end of the bed to the product end of another bed; followed by (2) withdrawing waste depressurization gas from the feed end of the bed while continuing to transfer gas from the product end of the bed to the product end of another bed; (3) during either or both of (1) and (2), transferring gas from the feed end of the bed to the feed end or ends of the one or more other beds; and (4) prior to (1), transferring gas from the product end of the bed at a higher pressure to the product end of another bed at a lower pressure.

  • Patent number: 6641645
    Abstract: A gas transfer segment of a vacuum swing adsorption process cycle utilizing multiple parallel adsorbent beds which undergo cyclic process steps to separate the components of a feed gas mixture, each bed having a feed end and a product end, wherein the gas transfer segment comprises a step of withdrawing a waste gas stream from the feed end of a first bed, withdrawing a transfer gas from the product end of the first bed and introducing the transfer gas into the product end of a second bed, and withdrawing a waste gas stream from the feed end of the second bed.

  • Publication number: 20030188634
    Abstract: A gas transfer segment of a pressure swing adsorption process cycle utilizing multiple parallel adsorbent beds, each bed having a feed end and a product end, wherein the gas transfer segment comprises transferring gas from a bed at a higher pressure to another bed at a lower pressure followed by withdrawing a waste depressurization gas from the feed end of the bed while transferring gas from the bed at a higher pressure to another bed a lower pressure.
