A bypass filter comprising a conduit having a main passageway configured for passage of fluid from an upstream end of the conduit to a downstream end of the conduit; The bypass filter further comprises a main filter located within the main passageway and configured for preventing passage therethrough of a predetermined substance within the fluid, while allowing a remainder of the fluid to pass towards the downstream end of the conduit; The bypass filter has an upstream opening in the conduit located upstream of the main filter and being in fluid communication with the main passageway at an upstream end of the conduit and a downstream opening in the conduit located downstream of the main filter and being in fluid communication with the main passageway at a downstream end of the conduit; The bypass filter also comprises an auxiliary filter being in fluid communication with both the upstream opening and the downstream opening for passing the fluid between the openings while at least partially absorbing the substance.

Provided are apparatus and systems for performing a swing adsorption process. This swing adsorption process may involve passing streams through adsorbent bed units to remove contaminants, such as water, from the stream. As part of the process, the adsorbent bed unit may provide access to the adsorbent material within the adsorbent bed unit without having to remove one or more of valves, conduits and manifolds.

An anaesthetic halocarbon capture system is provided. The system comprises a pressure-intolerant sleeve containing filter material for capturing one or more types of anaesthetic halocarbon prior to supercritical fluid extraction, and a pressure-tolerant housing into which the sleeve can be inserted so as to permit exposure of the sleeve contents to pressures required for supercritical fluid extraction.

Systems and methods of direct air capture are described. Systems include a plurality of moving adsorber panels in a linear direction (or circular configuration) and one or more fans configured to move air across the adsorber panels; such adsorber panels may be oriented vertically or horizontally, relative to the ground. Systems may include an independent regeneration box that comprises a system of headers, ducts and valves configured to deliver and remove a plurality of gases to the regeneration box. The regeneration box contains multiple chambers such that steps such as oxygen removal and panel cooling may be performed independently from and simultaneously to thermal preheating and desorption of the CO.sub.2 on the panels. The desorption panels may be configured to achieve counter-current flow to the hot gases used for thermal preheating and desorption. A multi-stage heat pump may facilitate reuse of waste heat and decarbonization of the process heating requirements.

System and method for removing molecular contaminants from an air stream are disclosed. The system includes first, second and third filter. The first filter removes organic contaminants from an air stream passing through the first filter. The second filter is downstream of the first filter, is physically and chemically exchangeable with the first filter and removes organic contaminants from the air stream output of the first filter. The third filter, downstream of the second filter, is not exchangeable with the first filter or the second filter. The first position filter can be replaced by the second filter in the second position when the first filter in the first position becomes depleted as detected. A new filter in the second filter position is inserted. Replacing the depleted first filter with the second downstream filter reduces costs and waste while inserting the new filter in the second position ensures removing organic contaminants.

A system is provided for collecting and logging the frequency of flatulence of a person in a selected time period as well as the duration of each occurrence of flatulence. The log entries provide determination of the body cells signaling of the person indicative of the person's health condition whereby underlying diseases may be detected and treated in their early stage.

A gas separation unit is disclosed for the separation of a first gas from a mixture containing said first gas as well as further gases by a cyclic adsorption/desorption process using a loose particulate sorbent material for gas adsorption. The plurality of particulate active material constructs are arranged in at least two stacked layers that are mounted on a stiff rectangular circumferential frame. Each layer of the particulate active material construct includes two sheets of a flexible fabric material which is hydrophobic and gas permeable but impermeable to a loose particulate active material for gas adsorption. A plurality of tubes is provided for a heat exchange fluid within the frame. The frame structure is provided with a plurality of holes through which the plurality of tubes penetrate.

This invention discloses a decontaminating column for on-line replacing adsorption material, and it includes: a tank having an inner tank being used for filling the adsorption material, and one end of the tank being set to be opened; at least one discharging part is being attached to the tank, and an open-close unit by which the adsorption material can be discharged and which is installed between the discharging part and the tank. There is a chamber in the discharging part, which is connected to a gas replacement unit. At the same time, this invention also discloses a glove box. Compared with the existing technology, this invention effectively solves the problems of low efficiency, high manufacturing cost and high maintenance cost generated by decontaminating column replacement mode in the existing technology; In addition, when the decontaminating column is used in the glove box, replacing the adsorption material can ensure that the water oxygen in the glove box is prevented from leaking out and/or the water oxygen outside of the glove box is prevented from penetrating into the box.
