Method and device for treating fluid liquid containing a volatile fraction

本发明涉及一种用于分离含有一种易挥发组分和一种重组分的含水量很大的液态流体的方法，包括以下步骤：点燃至少一种气态流体，以产生一种燃气；利用包括一个第一气/液热交换器和一个第二液/液热交换器的热回收回路回收燃气的热量来加热液态流体；使再加热的液态流体在加压条件下循环；利用蒸发提取液态流体中的易挥发组分；使待处理液态流体与其易挥发组分中排出的部分流体一起循环；通过燃烧使易挥发组分氧化；萃取浓缩状态的重组分，该方法可以对至少一种液态流体和至少一种气态流体同时进行处理。本发明还涉及一种用于分离含有一种易挥发组分和一种重组分的含水量很大的液态流体的装置。 A method for treating at least one liquid fluid comprising a high water content, and including a volatile fraction and a heavy fraction, in order to separate said two fractions. Said method consists in burning at least one gas fluid, recuperating the heat released by said combustion for subsequently heating the liquid fluid. The heated liquid fluid is pressurised and then expanded so as to separate the volatile fraction from the heavy fraction. The volatile fraction is then burnt with the gas fluid. The heavy fraction is extracted from the process to be subsequently treated. The invention also concerns an installation for implementing the treatment method.
