An atmospheric water generation system with high efficiency is based on a counter flowing heat exchanger including multiple cold channels, each cold channel surrounded by multiple hot channels. The hot and warm gases flow in opposite directions, allowing the cool dry air to contribute to cooling the warm humid air to the dew point. Thermoelectric or passive cooling of the warm humid air, and hydrophobic surfaces in a cyclone structure also contribute in increasing the efficiency of the water generation system.

A distillation apparatus includes at least one evaporation space in which feed water is evaporated into a vapour and at least one condensation space, in which vapour from a preceding evaporation space is condensed into distillate. The evaporation space and the condensation space each include a chamber and a plurality of interdigitated pockets arranged between said chambers, such that a first pocket of the evaporation space is present between a first and a second pocket of the condensation space, and that the first pocket of the condensation space is present between the first and a second pocket of the evaporation space. The spaces are mutually separated by means of a separation barrier that is configured for transmission of heat and for definition of the interdigitated pockets.

The invention provides a method for computational fluid dynamics and apparatuses making enable an efficient implementation and use of an enhanced jet-effect, either the Coanda-jet-effect, the hydrophobic jet-effect, or the waving-jet-effect, triggered by specifically shaped corpuses and tunnels. The method is based on the approaches of the kinetic theory of matter providing generalized equations of fluid motion and is generalized and translated into terms of electromagnetism. The method is applicable for slow-flowing as well as fast-flowing real compressible-extendable generalized fluids and enables optimal design of convergent-divergent nozzles, providing for the most efficient jet-thrust. The method can be applied to airfoil shape optimization for bodies flying separately and in a multi-stage cascaded sequence. The method enables apparatuses for electricity harvesting from the fluid heat-energy, providing a positive net-efficiency. The method enables generators for practical-expedient power harvesting using constructive interference of waves due to the waving jet-effect.

A hydrocyclone for separating a vapor from a carrier gas is disclosed. The hydrocyclone comprises one or more nozzles. A cryogenic liquid is injected to a tangential feed inlet at a velocity that induces a tangential flow and a cyclone vortex in the hydrocyclone. The carrier gas is injected into the cryogenic liquid, causing the vapor to dissolve, condense, desublimate, or a combination thereof, forming a vapor-depleted carrier gas and a vapor-enriched cryogenic liquid. The vapor-depleted carrier gas is drawn through a vortex finder and the vapor-enriched cryogenic liquid is drawn through an apex nozzle outlet. In this manner, the vapor is removed from the carrier gas.

A distillation system receives a feed solution to produce residue and distillate. A heat pump includes parts of a first and second heat exchangers, a working fluid, a working fluid compressor, and an expansion device. The working fluid receives available heat energy from the distillate in the second heat exchanger, receives at least some additional heat energy in the working fluid compressor, and releases at least some of that heat energy into the feed solution in the first heat exchanger. The first heat exchanger receives the feed solution, permitting transfer of at least some heat energy into it. A separator receives the feed solution from the first heat exchanger and separates it into the residue and distillate. The second heat exchanger receives the distillate, permitting transfer of at least some heat energy back into the working fluid. And a distillate extractor directs the distillate out of the second heat exchanger.

A method for treating arsenic-containing flue gas is disclosed. In the method, the arsenic-containing flue gas is subjected to a dry pre-dedusting treatment, and the dedusted flue gas is pre-cooled and then introduced into a vortex quenching system. The arsenic-containing flue gas is divided into high-temperature flue gas and low-temperature flue gas through the vortex quenching system. The outlet temperature of the low-temperature flue gas is dropped below the desublimation temperature of gaseous arsenic trioxide. The low-temperature flue gas is subjected to a gas-solid separation to obtain solid arsenic trioxide and treated flue gas.

The invention discloses a condenser for a bioreactor exhaust, comprising: an inlet (1) adapted to be fluidically connected to a bioreactor exhaust port (2), a cooling chamber (3; 103) fluidically connected to the inlet and via a filter device (4) to an outlet (5), a cooling conduit (6; 106) in contact with the cooling chamber, a heating conduit (7) in contact with the filter device and a vortex tube (8) arranged to convey a cold gas stream through the cooling conduit and to convey a hot gas stream through the heating conduit.
