Apparatus for producing liquid water from the condensation of atmospheric water vapor includes a transportable housing defining a first air inlet, a second air inlet, and an air outlet; first and second doors operable selectively to open and close the first and second air inlets, respectively; and at least one water condensation unit located in the housing between the first air inlet and the air outlet, and between the second air inlet and the air outlet. The housing is configured so that, when at least one of the first and second air inlets is open, at least a portion of an air flow into the at least one open air inlet is passed through the at least one condensation unit and out the air outlet.

A Vapor Recovery Unit (VRU) includes a VRU heat exchanger and a sorbent material for the recovery of hydrocarbon vapors from the ullage of tanks. The VRU heat exchanger and sorbent material are useful in conjunction with a thermal transfer fluid to control the temperatures of the sorbent material during endothermic and exothermic reactions that occur when hydrocarbon vapors are adsorbed and desorbed, which increases performance and reduces the amount of sorbent material required to recover hydrocarbon vapors.

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.

The invention relates to an arrangement for a latent-heat exchanger chamber, usable in distillation devices, which comprises an evaporator in a capillary evaporation regime on the inner face thereof and a condenser in a capillary condensation regime on the outer face thereof, with a system for the dosed supply of liquid into microgrooves or micro undulations of the inner evaporator face, preventing the formation of thin films of water on the evaporator face, the arrangement achieving high latent-heat transfer coefficients.

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.

Vapor flow-diverting devices that re-direct upwardly flowing vapor, for example, in a downward direction across condenser tubes disposed in the upper or top section of a vapor-liquid contacting apparatus, are described. These devices are particularly beneficial in tubular condensers within distillation columns and may be used in combination with other associated equipment (e.g., a deflector plate and divider plate) as well as in combination with the tube surface enhancements to improve the heat transfer coefficient.

This technology relates to the enlargement by water condensation in a laminar flow of airborne particles with diameters of the order of a few nanometers to hundreds of nanometers to form droplets with diameters of the order of several micrometers. The technology presents several advanced designs, including the use of double-stage condensers. It has application to measuring the number concentration of particles suspended in air or other gas, to collecting these particles, or to focusing these particles.
