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
摘要:
Process for manufacturing epichlorohydrin, comprising: (a) preparing epichlorohydrin to obtain a mixture comprising epichlorohydrin and water; (b) subjecting the mixture obtained in step (a) to a liquid-liquid phase separation to separate at least one first fraction (I) comprising most of the epichlorohydrin which was contained in the mixture before separation and at least one second fraction (II) comprising most of the water which was contained in the mixture before separation; and (c) drawing off the fraction (I) and the fraction (II); wherein the volume VI of the fraction (I) obtained in step (b) expressed in m3, the volume VII of the fraction (II) obtained in step (b) expressed in m3, the draw-off flow rate DI of the fraction (I) in step (c) expressed in m3/h, and the draw-off flow rate IN of the fraction (II) in step (c) expressed in m3/h, correspond to the following formula: (VII/VI)
