  • Patent number: 12270569
    Abstract: Water removal from humidified air and other water-laden gases may be complicated due to the need for large and expensive capital equipment or use of powder-form desiccants that may lead to pressure drops, poor throughput and energy-intensive recovery of water. Reversible water-absorbing constructs may alleviate these difficulties and comprise: a phase change polymer exhibiting a reversible hydrophilic-hydrophobic phase transition, and at least one additional material in contact with the phase change polymer, such as a water-sorptive material. The phase change polymer and the at least one additional material are formed as a plurality of filaments. Filaments formed from the phase change polymer may be generated through an electrospinning process, which may be arranged in various higher level constructs, such as in fibers, fabrics and non-woven filament mats capable of absorbing water from humidified air or other water-laden gases.

  • Patent number: 12247782
    Abstract: A method and apparatus for purifying air via a pre-purification unit (PPU) of an air separation unit (ASU) system can include passing air through a first adsorber of the PPU to purify the air for operation of the ASU system while it is at or below a first pre-selected operational capacity. In response to the operational capacity of the ASU system needing to be increased to a level above the first pre-selected operational capacity threshold, a second adsorber can be brought on-line in parallel with the first adsorber or in series with the first adsorber to provide improved purification capacity to account for the increased demand for purification capacity resulting from the increased operational capacity of the ASU system. This second adsorber can be different from the first adsorber (e.g. different in size, adsorption capacity for impurities within air, and/or configuration, etc.).

  • Patent number: 12234416
    Abstract: The present disclosure relates generally to processes and systems for producing liquid transportation fuels by converting a feed stream that predominantly comprises isobutane. The feed stream is catalytically-activated in two separate reaction zones arranged in series in a manner that minimizes the production of C1-C3 light paraffins and is tolerant to the presence of typical catalyst poisons. The first reaction zone is selective for conversion of the feed stream to predominantly olefins and some aromatics. The second reaction zone is maintained at a lower temperature and a higher pressure and is selective for converting olefins to monocyclic aromatics which facilitates further feed stream olefination. Certain embodiments contact the activation effluent with an alkylation catalyst to provide enhanced yields of upgraded hydrocarbon products that meet specifications for a transportation fuel blend component.
