Abstract: A process for treating gases comprising fluorinated compounds is disclosed. The process comprises passing a dilute fluorinated compound gas stream comprising a fluorinated compound to a scrubber to scrub it of reactive gases. A scrubbed gas stream is discharged from the scrubber and fed to an adsorption unit to adsorb one or more fluorinated compounds onto an adsorbent. One or more fluorinated compounds are desorbed from the adsorbent. A concentrated gas stream comprising a higher concentration of the fluorinated compounds than the feed gas stream is discharged from the adsorption unit.

Abstract: A spin contactor is provided for contacting a particulate with a fluid. The spin contactor has a containment section that may contain the particulate, a fluid inlet, and a fluid outlet. The containment section comprises an upper particulate separator, a lower particulate separator, and a conical wall. In most cases, the spin contactor includes a shaft to be operatively coupled to a means for spinning the spin contactor. The fluid is drawn upwardly through the fluid inlet to contact the particulate and then expelled through the fluid outlet. A process of treating a fluid composition is provided by sending the fluid composition through the spin contactor comprising particulates.

Abstract: A liquefied gas system for capturing boil-off gas and reversibly adsorbing the boil-off gas on an adsorbent for later desorption and use comprises a first vessel for storing liquefied gas; a means for delivering gas from the first vessel to a system endpoint; a second vessel for storing boil-off gas emitted from the first vessel, the second vessel containing at least one adsorbent; a means for delivering boil-off gas from the first vessel to the second vessel, whereby the boil-off gas is reversibly stored on the at least one adsorbent; and a means for delivering the stored boil-off gas from the second vessel to the system endpoint.

Abstract: An apparatus is provided for the storage and dispensing of a sorbable gas. The apparatus includes a storage and dispensing vessel constructed and arranged for containing a solid-phase physical sorbent medium having a sorbable gas adsorbed by said sorbent medium. The dispensing vessel includes a top head having a dispensing valve coupled to the vessel for discharging the sorbable gas therefrom. The dispensing valve is in fluid flow communication with a wick that extends below the upper third of the vessel top head. The wick collects the sorbable gas for discharge of the gas through the dispensing valve.

Abstract: This invention relates to a Cu-BTC MOF which is water stable. The Cu-BTC MOF has been modified by substituting some of the BTC ligand (1,3,5, benzene tricarboxylic acid) with 5-aminoisophthalic acid (AIA). The resultant MOF retains at least 40% of its as synthesized surface area after exposure to liquid water at 60° C. for 6 hours. This is an unexpected result versus the MOF containing only the BTC ligand. This MOF can be used to abate contaminants such as ammonia in gas streams and especially air streams.

Alternatively, the adsorbent can comprise a polymer functionalized with either 2,4,6,-dimercaptotriazine-ethylenedithiol (DMT-EDT) adduct, 2,4,6,-trimercaptotriazine-ethylenedithiol (TMT-EDT) adduct, or a combination thereof, and the polymer can be either a macroreticular polymer or a swellable polymer. The adsorbents can be used in either continuous or batch processes for removing contaminants from an API-containing feed stream wherein the contaminants can include elemental impurities, particularly palladium.

This is an unexpected result versus the MOF which has not been post treated with ligands such as acetonitrile. This MOF can be used to abate contaminants such as ammonia in gas streams and especially air streams.

The adsorbent material comprises at least one Lewis basic functional group, or pores of a size to hold a single molecule of the highly reactive gas, or inert moieties which are provided to the adsorbent material at the same time at the same time as the highly reactive gas, prior to adsorbing the highly reactive gas or after adsorbing the highly reactive gas, or the highly reactive gas reacts with moieties of the adsorbent material resulting in passivation of the adsorbent material. A rate of decomposition of the adsorbed highly reactive gas is lower than a rate of decomposition for the neat gas at equal volumetric loadings and equal temperatures for both the adsorbed highly reactive gas and the neat gas.
