FIELD: chemical or physical processes.
SUBSTANCE: invention relates to a method and a system for irreversible extraction of carbon dioxide from sea water for its subsequent irrecoverable disposal, which leads to a change in the equality of partial pressures of carbon dioxide at the interface between water and atmosphere and the transition of carbon dioxide from atmosphere into world waters, thus causing a trend of reduction of planet heating. Water is taken from the depth by means of airlift 1, into which compressed gas is supplied with provision of partial separation of dissolved carbon dioxide from water. Final separation of carbon dioxide from water is carried out by desorption in stripper 4 of residual amount of dissolved carbon dioxide, removal of moisture from it in apparatus 5, compression of carbon dioxide in compressor 6, separation of condensed water vapors from it in separator 7, cooling in refrigerator 9 and adsorption drying of carbon dioxide in block of adsorbers 10. Then, at least part of dried carbon dioxide is liquefied. At least part of liquefied carbon dioxide is collected in a container, from which liquefied carbon dioxide is removed by pipeline transport or pumped into containers for subsequent disposal.
EFFECT: reduced power consumption for the process of carbon dioxide extraction from sea water, increased efficiency of the process.
