Abstract

A method for purifying a liquid in a cycle, in particular a liquid originating from a mineral oil well, in which the liquid is stripped of suspended components in a closed cycle, and spaces above the liquid are being kept filled with an oxygen-free gas under some overpressure so as to prevent oxygen dissolving in said liquid.
