The present invention relates to a process cycle that allows for the stable production of mid-range purity oxygen from air, using traditional system designs. Typical cycles have a limited production benefit when generating O.sub.2 at lower than 90% purity, however they suffer a production loss at higher purity. The process cycles of the invention are capable of producing significantly more contained O.sub.2 at a lower purity. In addition to enhanced production capacity, lower power consumed per mass of product and more stable product purity and flow are realized by the process of the invention compared to traditional alternatives.

A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.

High-purity gas purifiers for purification of corrosive gases, such as halogen gases or halide gases, and noncorrosive gases, such as hydrogen and inert gases, methods of making and methods of using the gas purifiers, are described. The gas purifier includes a housing made of nickel or stainless steel. Within the housing, the gas purifier includes a purifier resin, including a modifi-er coated onto a substrate. The gas purifier further includes porous nickel membranes located at the inlets and outlets of the device. The inlets and outlets are capable of fluid communication with external fixtures.

An adsorption device for compressed gas, is provided with a vessel with an inlet for the supply of a compressed gas to be treated, and an outlet for treated gas and an adsorption element is affixed in the vessel. The adsorption element extends along the flow direction of the compressed gas to be treated, between the inlet and the outlet. The adsorption element has a monolithic supporting structure that is at least partially provided with a coating that contains an adsorbent.

An apparatus for capturing a water content from a water containing gas, the apparatus comprising: a housing having an inlet into which the water containing gas can flow; a water adsorbent enclosed within the housing, the water adsorbent comprising at least one water adsorbent metal organic framework composite capable of adsorbing a water content from the water containing gas, the metal organic framework composite comprising: at least 50 wt % water adsorbent metal organic framework; from 0.2 to 10 wt % magnetic particles having a mean particle diameter of less than 200 nm; and at least 0.1 wt % hydrophilic binder comprising a hydrophilic cellulose derivative; and a water desorption arrangement in contact with and/or surrounding the water adsorbent, the water desorption arrangement being selectively operable between (i) a deactivated state, and (ii) an activated state in which the arrangement is configured to apply heat to the water adsorbent to desorb a water content from the water adsorbent, wherein the water desorption arrangement comprises an alternating current (AC) magnetic field generator located within and/or around the water adsorbent configured to apply an AC magnetic field to the water adsorbent.

The invention relates to a fluid distributor (9, 10) for a column (1) comprising at least one cell (2) containing a bed of particles (3), the fluid distributor (9, 10) comprising: a floor (11, 21) comprising at least one injection point (15, 25) providing a fluidic connection on either side thereof; a layer of a resistive medium (12, 22) fixed on one face of the floor (11, 21), the resistive medium being permeable to the fluid; a spacing device (13, 23) inserted between the floor (11, 21) and the layer of resistive medium (12, 22) and maintaining a space for the circulation of the fluid between the floor (11, 21) and the layer of resistive medium (12, 22). The invention also relates to a column, in particular a chromatography column, provided with this fluid distributor.

An activated carbon device for adsorbing solvent from a flow of air is regenerated by feeding heated inert gas to the activated carbon and by applying a reduced pressure to the heated activated carbon.

An internal air adjustment device that includes a first composition adjustment unit and a second composition adjustment unit. The first composition adjustment unit separates supply air from external air, the supply air having a composition that differs from a composition of the external air, and supplies the supply air into a transport container. The second composition adjustment unit separates discharge air from internal air, the discharge air having a composition that differs from a composition of the internal air, and discharges the discharge air to outside of the transport container. The internal air adjustment device is capable of properly controlling the composition of the internal air in the transport container.

A method of continuous ozone production using a system of four absorbent beds to separate an ozone and oxygen gas mixture generated in an ozone generator. The beds are operated according to an offset sequence of cycles. Oxygen passing through the beds is at least partially recycled for use in further ozone generation. The concentration of oxygen in the ozone product can be reduced using the system to make it suitable for use in fine chemical applications.

A carbon dioxide absorbent of an embodiment includes a solid resin compound containing a structural unit expressed by the following formula (1). X in the formula (1) is a halogen element.
