    摘要： A process for purifying a brine of organic compounds comprising: (a) supplying a brine that comprises at least one organic compound; (b) feeding at least one stripping zone with the brine from (a) and at least one stripping agent; (c) withdrawing from the stripping zone at least one fraction (I) consisting essentially of brine, the content of the organic compound being lower in fraction (I) than in the brine from step (a), and at least one fraction (II) consisting essentially of the stripping agent; wherein the temperature (T1) of the hotter fraction of the two fractions (I) and (II) and the temperature (T2) of the colder fraction of the two fractions (I) and (II), such temperatures expressed in degrees Celsius being the temperatures measured before any possible thermal conditioning which might be carried out before and/or during their withdrawal from the stripping zone, correspond to the following formula: 6×10−7(T1)3.7294≦T2
