A system and a method for continuously separating carbon dioxide from gas mixtures, utilizing a continuous loop of porous monoliths which support a sorbent within its pores. Continuously exposing a portion of the continuous loop of monoliths to a flow of gas mixture containing a minor proportion of carbon dioxide, to adsorb carbon dioxide from the flow. The loop passes through a sealed regeneration and carbon dioxide capture assembly located astride a portion of the loop, and which is capable of sealingly containing a monolith in relative movement through the assembly. The assembly chamber comprises a plurality of separately sealed zones, including at least one zone for purging oxygen from the monoliths, -a subsequent zone for heating the monolith to release the adsorbed carbon dioxide, and another cooling zone for cooling the monolith prior to reentering the adsorption portion of the loop where it is exposed to oxygen.

The disclosure provides an apparatus, as well as associated systems and methods for removing acid gas components from gas streams. The disclosure provides a rotating packed bed (RPB)-based absorber with a non-aqueous liquid solvent contained therein for treatment of the gas streams, wherein the non-aqueous liquid solvent captures acid components from the gas stream. Various advantages, e.g., with respect to spatial considerations and associated expenses can be realized using the apparatus, systems, and methods described herein.

A method and system for an enhanced reforming process employing a pressure swing absorber. An off-gas from the pressure swing absorber is divided with a first portion sent back into a reforming reactor and a second portion sent to a heat generator for the reforming process. The first off-gas portion from the pressure swing absorber can be pressurized by a compressor and reintroduced into a fluidized bed reactor.

Air purification and dehumidification apparatus includes a first cooler that cools air introduced through a first inlet, a first rotor that primarily adsorbs and absorbs VOCs and moisture contained in the air cooled by the first cooler, an air conditioning unit that cools or heats the air primarily purified and dehumidified by the first rotor, a blower that moves the air cooled or heated by the air conditioning unit, a second rotor that adsorbs and absorbs VOCs and moisture remaining in the air moved by the blower, a second cooler that re-cools the air secondarily purified and dehumidified by the second rotor, a first heating unit that heats air that is introduced through a second inlet and is then supplied to the first rotor, using sequentially solar energy and electric energy, and a third cooler that condenses air containing the VOCs and moisture that are released from the first rotor.

A dehumidifying air handling unit for an HVACR system includes a housing, a desiccant wheel, and a cooling heat exchanger. A main airflow path extending through the housing from an air inlet to and air discharged outlet of the housing. The desiccant wheel includes a first end and a second end that are each disposed in the main airflow path and a metal organic framework desiccant that is moved between the first end and the second end. A desiccant wheel includes a metal organic framework desiccant disposed on a surface of the desiccant wheel. Rotation of the desiccant wheel moves a position of the surface between a first end and a second end of the desiccant wheel. The metal organic framework desiccant has an majority absorption-desorption operating band of 25% relative humidity or less.
