METHOD FOR WATER OBTAINING FROM AIR Russian patent published in 2006 - IPC E03B3/28 B01D53/04 F25D17/06 

FIELD: obtaining fresh water from atmospheric air in remote, dry or arid zones.

SUBSTANCE: method involves creating air flow with air blower; supplying air flow through air ducts, valves and heat-exchangers; absorbing water steam from air flow by sorbent at absorption stage; heating sorbent layer at desorption stage by heat generators arranged directly in sorbent layer; removing desorbed water steam from sorbent layer; condensing water steam in condenser and accumulating thereof in storage vessels. The heat generators are heat-exchangers with developed surfaces distributed in sorbent layer and sorbent heating is performed due to water steam condensation on heat-exchanger surfaces. Besides, electric heaters may be used as the heat generators. The electric heaters are also distributed in sorbent layer and are heated by alternating current supplied thereto. The heat generators may be formed as current-conducting sorbent layer heated by electric current. Catalyst may be also used as the heat generators. The catalyst is located in sorbent layer and adapted to provide hydrocarbon oxidation reaction.

EFFECT: increased quality of obtained fresh water and reduced power consumption for fresh water obtaining.
