A solid desiccant cooling system and method of operating a solid desiccant cooling cycle is provided comprising a desiccant support structure for cyclic movement of solid desiccant between a first location where a solid desiccant contacts a source of air to be dehumidified and a second location with a solid desiccant is regenerated. A heat exchange arrangement is provided preferably at the first location. The heat exchange arrangement provides a heat exchange or thermal engagement of a heat exchange fluid e.g. water, with the desiccant containing tubes. The proposed method and apparatus cools the desiccant while dehumidification of air is conducted. Preferably, the heat exchange fluid is provided to the desiccant support structure at a position at or adjacent its longitudinal axis, to flow radially therefrom.

A carbon dioxide recovery apparatus has: a separator that separates carbon dioxide from a gas and discharges a residual gas from which carbon dioxide has been removed; a dryer having a hygroscopic agent for drying the gas to be supplied to the separator; and a regeneration system which supplies the residual gas to the dryer as a regeneration gas for regenerating the hygroscopic agent in the dryer. The separator utilizes adsorption/desorption of carbon dioxide to an adsorbent caused by pressure fluctuation. A supplement system supplies a supplement gas from an outside to the residual gas depending on a flow rate of the residual gas discharged from the separator such that a flow rate of the regeneration gas is a predetermined rate.

A treater regeneration system in a polyolefin production system, the treater regeneration system comprising an off-line treater receiving a first portion of a regenerating stream and regenerating a desiccant in the off-line treater to yield a regenerating effluent stream, where the regenerating stream comprises a regenerating medium, and where the regenerating effluent stream comprises the regenerating medium, water and an impurity; a decanter receiving at least a portion of the regenerating effluent stream to yield the regenerating stream and a water stream, wherein the water stream comprises the water; and a stripper receiving a second portion of the regenerating stream to yield an impurity stream and a process recycle stream, wherein the impurity stream comprises at least a portion of the impurity, and wherein the process recycle stream comprises the regenerating medium of the second portion of the regenerating stream.

This disclosure includes regenerated inorganic fermented beverage stabilization and/or clarification media and a process for such regeneration. Inorganic stabilization and clarification media (for processing beer or the like) may include expanded perlite or other expanded natural glasses, diatomaceous earth, silica gel or other precipitated silicas and compositions that incorporate these materials. Such media may be regenerated individually, together in a mixture or together as part of a composite product. The regenerated media meet the requirements for physical and chemical properties for re-use and replacement of the majority of particulate inorganic filtration media, and inorganic stabilization media consumed in stabilization and clarification processes, and the related regeneration process provides for substantial benefits to brewers through a reduction of costs to purchase and transport stabilization and clarification media, to dispose of spent cake and/or membrane retentate, while providing for substantial reductions in the introduction of soluble impurities into the fermented beverage.

The invention relates to devices, systems, and methods for recharging zirconium phosphate and/or zirconium oxide in reusable sorbent modules. The devices, systems, and methods provide for precision recharging of the zirconium phosphate and/or zirconium oxide to avoid the need of excess recharge solutions. The devices systems and methods also provide for calculation of the volumes of recharge solution needed for fully recharging the zirconium phosphate and zirconium oxide modules.

Disclosed in certain embodiments are sorbents for capturing heavy hydrocarbons via thermal swing adsorption processes.

A process for the extraction of lithium from a brine, wherein a solution of the brine is contacted with a titanate adsorbent such that lithium ions are adsorbed thereon whilst rejecting substantially all other cations. The adsorbent is provided in the form of either a hydrated titanium dioxide or a sodium titanate. The process in turn produces a substantially pure lithium chloride solution

The invention relates to systems and methods for recharging sorbent materials and other rechargeable dialysis components. The systems and methods include rechargers, flow paths, and related components for connecting multiple rechargers together to sharing infrastructure and resources. The rechargeable dialysis components can include zirconium phosphate, zirconium oxide, and other sorbent cartridge materials including any combination thereof or any other rechargeable component of a dialysis system. Additionally, a single-use cartridge or a multi-use cartridge can be used in the present invention.

A pod for removing odor and moisture from a substantially confined area has deodorant and moisture adsorbing properties to counteract unpleasant odours, especially odours due to microbial growth. The pod is removably insertable into footwear, gloves, skates, lockers, sports gear, workout gear or any gear or enclosure. The pod has a fabric pouch with anti-microbial properties and contains fragrance-releasing particles and desiccant granules. The moisture adsorbing properties of the pod may be thermally rechargeable. The pods may be attached to other pods in use.

Embodiments of the present disclosure may include a method for increasing the efficacy of reducing a concentration of an at least one metal from a volume of produced water, the method including injecting a gas nanobubble into the volume of produced water. Embodiments may also include exposing a volume of produced water infused with nanobubbles to a sorbent composition for a contact time. In some embodiments, the sorbent composition may be a large format composition of at least 150 microns in dimension. Embodiments may also include removing the produced water after the contact time elapses. Embodiments may also include rinsing the sorbent composition after the cycle time. Embodiments may also include exposing the rinsed sorbent composition to a reagent infused with nanobubbles to produce at least one metal eluate.
