An atmospheric water generation system absorbs water from an atmospheric air stream into a desiccant flowing along a flow path of a closed desiccant circulation loop. To ensure that the desiccant remains within the closed desiccant circulation loop, the atmospheric water generation system encompasses a membrane-based water extraction device that the desiccant flows through. The desiccant flows through the membrane-based water extraction device on a first side of a membrane, and the membrane separates the desiccant from a water-collection flow. Water absorbed into the desiccant passes from the desiccant, through the porous membrane, and into the water-collection flow, at least in part due to differences in temperature and/or pressure characteristics of the water flow and the desiccant flow. Water collected within the water-collection flow is directed to a storage tank for usage.

The present invention discloses a novel multipurpose fast dehumidification device, in which materials with different functions can be placed simultaneously or separately, such as moisture absorption materials, aromatic materials, mosquito repelling (insect repelling) materials or deodorization materials. The present invention comprises a base, a placement frame and a circulation mechanism One end of the placement frame is movably connected with the base, and the other end of the placement frame is movably connected with the circulation mechanism; and the moisture absorption materials are placed in the placement frame. After the device is started, air in an environment is sucked by the circulation mechanism, then reaches the placement frame, and then is discharged from the placement frame after being dehumidified. The present invention has the beneficial effects that the structure is simple, and the use is convenient; the complicated structure of a traditional dehumidifier is abandoned, and the cost of a product is reduced to a maximum degree; at the same time, a single dehumidification function is expanded, which can play a role in different use scenes. That is, besides the dehumidification function, functions of atmosphere creation, mosquito repelling (insect repelling), deodorization and the like can also be realized.

Device for extracting water from humid ambient air, the device including a conduit in which successively is incorporated: a compressor to compress the humid ambient air into compressed ambient air, a first condenser to dry the compressed ambient air into dry compressed air, an expansion valve or expander for expanding the dry compressed air into dry expanded air and a second condenser. The first condenser is further configured to direct the wet ambient air through it as coolant for extracting water from the compressed ambient air in a first stage via an outlet or the like. The second condenser is configured to direct the dry expanded air through it as coolant for extracting the water from the humid ambient air in a second stage by means of an outlet or the like.

A device for drying compressed gas, having an inlet for compressed gas to be dried and an outlet for dried compressed gas. The device includes at least two vessels, a regenerable drying agent and a controllable valve system. By controlling the valve system, the vessels are each in turn successively regenerated. The device is provided with a regeneration conduit splitting off a portion of the dried compressed gas as a regeneration gas and feeding it into the at least one vessel that is being regenerated. The regeneration conduit at least partly extends through an opening in the vessels such that the regeneration gas can be split off from the vessel that dries the compressed gas. A heater is provided in the regeneration conduit for heating the regeneration gas before the regeneration gas is fed through the drying agent into the vessel that is being regenerated.

A natural gas pretreatment system includes a heat exchanger having a first inlet, a second inlet, a first outlet, and a second outlet. The first inlet receives a first pressurized gas stream having a first input temperature, and the second inlet receives a second pressurized gas stream having a second temperature. The second temperature is higher than the first temperature. The first outlet outputs the first gas stream; upon exiting the heat exchanger, the first gas stream has a first output temperature higher than the first input temperature. The second outlet outputs the second gas stream; upon exiting the heat exchanger, the second gas stream has a second output temperature lower than the second input temperature. The system further includes a pipeline network operable to receive the first pressurized gas stream.

A method for generating liquefied gas is provided. The method includes receiving air, refining the air to create refined air, performing liquefaction on refined air to form liquefied gas, and transferring at least one constituent liquefied gas of the liquefied gas to a storage tank in a lighter than air aircraft. The constituent liquefied gas(es) is configured to serve as an energy source for the lighter than air aircraft. The method may include distilling the liquefied gas to obtain liquid nitrogen and one or more other constituent gases. The liquid nitrogen may be configured to store at least 250 kilojoule per liter of energy. Additionally, the air may be refined to create refined air by compressing the air, separating water from the air, scrubbing carbon dioxide from the air, and/or filtering dust from the air. The method may be carbon-neutral or carbon-negative.

The present invention describes methods for absorbing a targeted chemical compound from a gas stream into a scrubbing solution for various uses and with various benefits. Methods are described to produce a gas stream that can be further processed with operational benefits, such as through condensing and wastewater treatment with a lower load on the wastewater treatment system. Methods are described for adsorbing the targeted compound with reduced condensation of water from the gas stream. Methods are described for producing a liquid stream comprising an absorbed form of the targeted compound for use as a saleable product, such as adsorbing ammonia for the production of a fertilizer, wherein the concentration of the absorbed form may be increased through reduced condensation from the gas stream. Methods are described for producing a lower volume liquid waste stream from the absorption process through the use of reduced condensation of the gas stream.

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.

A sanitizing spray system includes a Nitrogen generation system that produces Nitrogen used as a carrier gas source for spraying an alcohol-based disinfecting and sanitizing composition without flashing.
