ABSTRACT:
The method for the deoxidation of chlorinated water, more particularly sea water, by means of a low oxygen content stripping gas, comprises a closed circuit in which a liquid absorbent circulates. For dechlorination, the liquid absorbent is brought into contact in an absorption column with the stripping gas charged with oxygen and chlorine. The absorbent is of a nature not to absorb at least one of the components comprising carbon dioxide, oxygen and hydrocarbons, and is fed to the absorption column by a pump from a reservoir in the circuit.
