  • Publication number: 20220096993
    Abstract: An adsorbent vessel for removing contaminants from a feed gas upstream from a cryogenic distillation process using pressure swing adsorption, temperature swing adsorption, or thermal-pressure swing adsorption. The adsorbent vessel having an adsorbent bed comprised of multiple layers of adsorbent material, including two layers of adsorbent material that selective adsorbs carbon dioxide. Each of the two layers is formed from an adsorbent material having a different capacity for adsorbing carbon dioxide.

  • Publication number: 20220099367
    Abstract: A chiller can be configured as a chiller for a gasification system or other type of system or plant. In some embodiments, the chiller can be configured to utilize a single heat source, such as low grade waste heat in the form of hot water, and/or low pressure steam to drive one or more absorption-based chillers to cool inlet air to one or more adsorbers of a pre-purification unit (PPU). In the event of the detection of an undesired impurity spike (e.g. carbon dioxide spike, etc.) an additional amount of heat source can be withdrawn from the gasification system to increase the level of cooling the absorption chiller can provide to improve the removal of impurities. An automated control loop can be utilized in some embodiments. The control loop can be configured to check for an impurity concentration and adjust operations accordingly.

  • Publication number: 20220016565
    Abstract: A radial adsorber can be configured to facilitate utilization of different layers of material. The radial adsorber, system using at least one radial adsorber, and methods of utilizing embodiments of the radial adsorber can help permit improved efficient operation of fluid purification processing while also being configured to minimize, if not fully avoid, being susceptible to the effect of fluidization.

  • Patent number: 10576455
    Abstract: Particle loading assembly and method for loading particles into a vessel to form a densely packed particle bed comprising an inner layer of particles and an outer layer of particles. The inner layer of particles is arranged radially and concentric with the outer layer of particles. The inner layer of particles contains at least a first type of particle of different granulometry or range of composition or both granulometry and range of composition from a second type of particles contained in the outer layer.

  • Patent number: 9199190
    Abstract: An adsorber vessel for the adsorption of gas contaminants from a gaseous stream comprising a vertical wall baffle positioned on an inner surface of an absorber vessel wall, and a bed support positioned below the vertical wall baffle and affixed to the inner surface of the adsorber vessel wall to support an adsorbent material, where the adsorbent material is interned by the bed support, the adsorber vessel wall, and the vertical wall baffle such that at least 90% of the volume created between the vertical wall baffle and the inner surface of the adsorber vessel is free of the adsorbent material.
