An apparatus and system for producing fresh water from moisture-laden air. The apparatus has a frame supporting a plurality of condensation panels that each have a panel body defining a pair of condensation surfaces that will contact the moisture-laden air. A panel support mechanism supports each of the condensation panels in spaced apart relation to each other so each condensation surface contacts moisture-laden air. A flow channel inside the panel body defines a flow path for a cooling fluid that cools the condensation surfaces so the moisture-laden air will produce condensate thereon that collects as fresh water. The system includes a plurality of apparatuses, a chilling mechanism to cool the cooled fluid, inlet and discharge lines connecting the chilling mechanism and apparatuses, pumps to pressurize the cooled fluid, fans to move the moisture-laden air and water collecting surfaces to collect the fresh water.

A carbon dioxide recovery device provided with a separation device that separates carbon dioxide from to-be-separated gas (for example, combustion exhaust gas) containing carbon dioxide, wherein: in order from the upstream side where the to-be-separated gas is supplied, the separation device and carbon dioxide sublimators, which sublimate (solidify) carbon dioxide that was separated in the separation device, are connected in series, refrigerant circuits in which a fluid having cold heat serves as the refrigerant, are connected to the carbon dioxide sublimators, and the refrigerant is used to sublimate (solidify) the carbon dioxide; and when the carbon dioxide is sublimated (solidified), the carbon dioxide sublimators are depressurized and set to negative pressure so as to draw in the carbon dioxide separated at the separation device.

The apparatus comprises a first air duct with a first opening and a second opening, in the first air duct are: a cooler, a first suction device and at least part of a sorption heat exchanger having an integrated heating and/or an upstream device for preheating the incoming air. An element for collecting condensed water is also included. The apparatus also comprises a recuperative heat exchanger, which is positioned in the first air duct between the cooler and the sorption exchanger and simultaneously also between the cooler and the second opening. The recuperative heat exchanger has at least two internal conduits connected in such manner, that the first of these internal conduits air-interconnects the sorption exchanger and the cooler and that the second of these internal conduits air-interconnects the cooler and the second opening. The first and second internal conduits of the recuperative heat exchanger are in mutual thermal contact. The sorption exchanger is also air-interconnected to the first opening.

The present disclosure provides a cup lid and a self-producing water cup. The cup lid includes: a housing, a condensing mechanism, and a heat dissipation mechanism. The housing defines a housing space, an air inlet, an air outlet, and a water outlet. The air inlet, the air outlet, and the water outlet are connected to an outside. The air inlet, the air outlet, and the water outlet are connected to the housing space. The condensing mechanism is housed in the housing and connected to the air inlet. The condensing mechanism is configured to condense air flowing from the air inlet into water, and the water flows out through the water outlet. The heat dissipation mechanism is housed in the housing and connected to the air outlet. The heat dissipation mechanism is configured to dissipate heat generated by the condensing mechanism.

A method and device are provided for purifying and recycling water vapor from a coal drying process. Included are a temperature-lowering and dehumidifying process, a flash distillation stripping process, and a vacuum condensing process. A condensing tower receives a temperature-lowered exhaust gas with high humidity from a cooling tube and a condensed water of 5˜60° C. from a flash distillation tank, allowing the exhaust gas and the condensed water to contact each other in a vapor-liquid reverse manner, to lower the temperature and dehumidify the exhaust gas. The flash distillation tank performs a vacuum flash distillation to the condensing water pumped therein from the condensing tower. Water vapor of 5˜60° C. evaporated through flash distillation in the flash distillation tank enters into the demisting washer to be dehumidified and then is condensed. The condensed water in the vapor condenser is transferred into a recycled water tank. Non-condensable gas is discharged out.

Disclosed herein is a fracturing unit for hydraulic fracturing having an engine and a fracturing pump connected to the engine through a variable speed torque converter. Also disclosed is a hydraulic fracturing system using multiple fracturing units which are sized similar to ISO containers. A hydraulic fracturing system may also force flow back water, produced water, or fresh water through a heat exchanger so that heat from the fracturing engines can be transferred to these liquids in order to vaporize them. A force cooled fractioning unit then can accept the vapor/steam in order to condense the various components and produce distilled water for re-use in the fracturing process or for release into the environment.

An atmospheric water generator (AWG) may be used to extract water from ambient air. A compact screw compressor of the AWG may be used to compress refrigerant, a condenser of the AWG may be used to condense refrigerant, an expansion device, and an evaporator of the AWG may be used to transfer heat from ambient air to refrigerant, causing moisture in the air to condense. The condensed moisture may be collected in a water collection unit.

A distribution chamber disclosed discharges a fraction which have been fractionally distilled in embodiments of the disclosed technology. The distribution chamber is removably connected to a distillation head such that between each fraction, the distribution head can be switched with another. Each such distribution head has a vertically extending drain and/or discharge port, or plurality thereof, to distribute a discharged fraction into a single flask, such port being at an acute angle to an intake port. In this manner, the discharge/drain port(s) can be vertically oriented and at a bottom side of the distribution chamber when the intake port is connected to the distillation head.

A water vapor collector assembly, which consists of an optional capillary net, a dome, a water conveying channel, an optional capillary mat, a floatation base, and a water tube anchor, which many of it can be looped together by ropes and tubes and can float on sea surface to take sun rays to generate freshwater.
