The present disclosure relates to a drier cartridge that can improve the effect of cleaning compressed air by filtering out water, oil, and foreign substances, which are contained in compressed air, through several steps therein. In particular, when a narrow compressed air channel is formed between a cartridge body and a cartridge housing, a collision member that is a pre-filtering member that can primarily filter out oil, etc. is formed between the cartridge body and the housing, whereby it is possible to improve the performance of removing oil and water from a filter cartridge.

The dryer is provided with a drying section and a regeneration section with an entry and an exit for regeneration gas. A regeneration pipe is connected to the entry and a heat exchanger is provided in the regeneration pipe with a primary section through which the regeneration gas is guided. A secondary section of the heat exchanger is mounted in the compressor device. The compressor installation is provided with means to regulate the amount of liquid injected in the compressor element.

A hydrogen gas supply apparatus includes a compressor configured to compress hydrogen gas and supply the compressed hydrogen gas toward a pressure accumulator which accumulates the hydrogen gas, a first adsorption column disposed between the discharge port of the compressor and the pressure accumulator and configured to include the first adsorbent for adsorbing impurities in the hydrogen gas discharged from the compressor, a first valve disposed between the discharge port of the compressor and the gas inlet port of the first adsorption column, a second valve disposed between the gas outlet port of the first adsorption column and the pressure accumulator, a return pipe configured to branch from between the first valve and the gas inlet port of the adsorption column and connect to the suction side of the compressor, and a second adsorption column disposed in the middle of the return pipe.

A hydrogen sulfide adsorption distiller using pure copper of the present invention has advantages in that, while alcohol vaporized in a heating vessel 100 sequentially passes through a retention tube 120, which is formed of pure copper having a catalytic reaction, a vertical tube 130, a spiral coil 132, a cooling vessel 140, and a liquid collecting vessel 150 until distilled liquor C of condensed liquefied alcohol is completed, vaporization process is facilitated, and at the same time, hydrogen sulfide of the vaporized alcohol and the condensed liquefied alcohol is adsorbed, and thus, hydrogen sulfide, which (adversely) affects the organoleptic flavour properties of distilled liquor C, is removed as much as possible, thus improving liquor quality.

Apparatuses, systems, and methods are provided for a breather for a reservoir is provided, including a housing including a plurality of valves, the plurality of valves including (i) at least one valve in a first configuration configured to permit fluid communication from an interior portion of the housing with air outside the reservoir, and (ii) at least one valve in a second configuration configured to permit air to selectively pass between outside the breather and an interior portion of the breather. The breather further includes a plurality of first openings in the housing configured to be in fluid communication with air outside of the reservoir, a second opening of the housing configured to be in fluid communication with air inside the reservoir, and desiccant positioned within the housing.

The present disclosure relates to a purge system for a vapor compression system, where the purge system includes an emission canister configured to receive a gas flow. The gas flow includes a mixture of non-condensable gases and refrigerant of the vapor compression system. An adsorbent material is disposed within the emission canister and configured to adsorb the refrigerant and enable the non-condensable gases to flow toward an exhaust of the emission canister, where the adsorbent material is a silica gel.

Method and apparatus for condensing a majority of the solvent in a process gas stream at low temperatures, e.g., below the freezing point of water, ca. −5° C. The gas stream exiting the condenser step may be further processed in one or more emission control devices, such as a single or multi-step series of concentrator devices, such as zeolite concentrator devices. One or more emission control operations can be carried out downstream of the single or multi-step concentrators. The aforementioned condensing process enables the one or more concentrators to operate in a favorable temperature range for removal of 99% or more of VOC, thereby meeting or exceeding strict environmental regulations.

Provided are apparatus and systems for performing a swing adsorption process. This swing adsorption process may involve performing dampening for fluctuations in the streams conducted away from the adsorbent bed unit. The process may be utilized for swing adsorption processes, such as rapid cycle TSA and/or rapid cycle PSA, which are utilized to remove one or more contaminants from a gaseous feed stream.

Disclosed are techniques such as roll to roll processing to produce membrane valves in microelectromechanical systems that are integrated with micro-pumps that include a pump body having compartmentalized pump chambers. One application of this technology is as a valve assembly for a gas concentrator that includes a first micro pump for feeding an input gas stream, a second micro pump to supplying a vacuum and at least one sieve bed having a zeolite. The gas concentrator uses the valve assembly for controlling entry of gas from the first micro pump into the sieve bed and the second micro pump to vent.

A canister includes a main casing, a first port formed in a wall of the main casing, and a first adsorbent section within the main casing. The first adsorbent section and the wall of the main casing define a space section therebetween. The first adsorbent section includes a first adsorbent and a first retainer holding the first adsorbent. The canister also includes a first elastic element disposed in the space section. The first elastic element urges the first retainer to elastically hold the first adsorbent. In addition, the canister includes a subcasing integral to the wall of the main casing. The subcasing is positioned within the space section. Further, the canister includes a second adsorbent section in communication with the first port. The second adsorbent section includes a second adsorbent disposed within the subcasing. Still further, the canister includes a second retainer holding the second adsorbent.
