Sorbent material sheets are wound around a center core of material that includes additional sorbent. This configuration further increases the packaging efficiency and performance of the sorbent material sheets as part of an overall housing or apparatus. In some embodiments, the sorbent material sheets are arranged in a stacked configuration. Configurations of the sorbent material sheets as part of a canister are also described.

Porous solid amine adsorbents are prepared by bringing into contact a first (e.g., dope) solution, including a water insoluble polymer and a water-soluble amine polymer, with an aqueous solution containing a multifunctional chemical agent. The first solution can be obtained by dissolving the water insoluble polymer and the water-soluble amine polymer in a polar solvent. The adsorbents can be in the form of beads, sheets, fibers, hollow fibers, etc. and can be used in the removal of acid gases, CO.sub.2, for instance, from fluid streams.

A DAC method as well as a unit containing an adsorber structure having an array of adsorber elements with a support layer and on both sides thereof a sorbent layer (1, 2), wherein the adsorber elements are parallel and spaced apart forming parallel fluid passages for flow-through of ambient atmospheric air and steam. The method involves the following sequential and repeating steps: (a) adsorption by flow-through; (b) isolating the sorbent; (c) injecting a stream of saturated steam through the parallel fluid passages and inducing an increase of the temperature; (d) extracting desorbed carbon dioxide from the unit and separating it from steam; (e) bringing the sorbent material to ambient temperature conditions wherein in step (a) the speed of the air is in the range of 2-8 m/s, and wherein at least in step (d) the speed of the steam is at least 0.2 m/s.

The present technology relates generally to parallel passage contactors having active layers and methods for its use. Particularly, the present technology relates to parallel passage contactors having active layers with sorbents and/or catalysts and methods of use in sorptive gas separation and/or catalytic reactions.

Disclosed is a method of controlling an air supply system for a fuel cell. The air supply system includes a fuel cell stack, an air channel to supply air to an inlet of the fuel cell stack, a gas adsorption unit disposed on the air channel and configured to adsorb oxygen contained in air introduced into the air channel. In particular, the method includes: determining whether a power generation operation of the fuel cell stack is resumed; when the power generation operation of the fuel cell stack is resumed, controlling a voltage source to apply a voltage to the gas adsorption unit; and supplying air to the fuel cell stack through the air channel in a state in which the voltage is applied to the gas adsorption unit.

A spacer for a body of a refrigerant tank—such as a modulator—in an automotive HVAC device is provided. In embodiments, the spacer is flexible to enable it to be inserted into the modulator, and expanded out against the walls of the modulator when released therein. The spacer inhibits a desiccant bag from contacting the inner wall of the modulator, namely the location where a hole (e.g., for an inlet or outlet) is provided. The spacer can be a cage that surrounds a lower portion of the desiccant bag. And end of the desiccant bag can wrap around a flange of the cage, and be attached to the flange by mechanical fastening (e.g., through a slot), or by welding, or other means.

An air purification system includes a conduit extending between an inlet and an outlet, each in fluid communication with an enclosed environment. Ambient air from the enclosed environment enters the conduit via the inlet and treated air exits the conduit and enters the enclosed environment via the outlet. The system further includes a fibrous filter disposed within the conduit and configured to treat the ambient air thereby generating the treated air, and a renewal unit disposed within the conduit and configured to renew the fibrous filter.

A system and method for capturing volatile organic components from a liner curing process for pipes. The system receives steam exhausted from the liner. The steam is used for curing a curable material in the liner, but volatilizes organic components in the resin carried along with the steam. The system removes some water and passes the remaining vaporized constituents through a filter selected to capture the particular volatile organic component from the steam.

Provided is a food waste disposer. The food waste disposer according to an embodiment of the disclosure includes: a housing; a grinder detachably installed inside the housing and configured to grind food waste accommodated therein; and a deodorizer positioned to a side of the grinder, and configured to suck a smell generated from the grinder and discharge the smell to outside of the housing, wherein the grinder includes: a grinding case; a rotating grinder including a plurality of blades rotatably installed at different heights inside the grinding case; and a wall grinder including a protrusion protruding inward from the grinding case at a different height from the plurality of blades, the wall grinder detachably installed on a side wall of the grinding case.

Some embodiments of the disclosure correspond to, for example, a method for controlling a scrubber containing an adsorbent. The scrubber may be configured to cycle between scrubbing at least one pollutant/gas from a stream of gases with the pollutant/gas being adsorbed onto the adsorbent, and regenerating at least some of the adsorbent and thereby purging at least some of the one pollutant and/or first gas from the adsorbent via a regeneration gas flow. The method may include flowing a stream of gases through the scrubber, the scrubber including the adsorbent and adsorbing at least some of the one pollutant/gas from the stream of gases onto the adsorbent during an adsorption phase over a first time period. The method may also include purging at least a portion of the one pollutant/gas from the adsorbent during a regeneration phase over a second time period with a regeneration gas flow, and cycling therebetween.
