摘要：
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) essentially constituted of brine, the content of organic compound of which is lower than in the brine from (a) and at least one fraction (II) essentially constituted of stripping agent; and in which the temperature, expressed in degrees Celsius (T
1 ), of the hottest fraction of the two fractions (I) and (II) and the temperature, expressed in degrees Celsius (T
2 ), of the coldest fraction of the two fractions (I) and (II), said temperatures being the temperatures measured before any possible thermal conditioning which might be carried out before and/or during the withdrawal thereof, correspond to the following formula: 6 x 10
-7 (T
1 )
3.7294 ≤ T2
