    摘要： The disclosed invention relates to a process for distilling a fluid mixture in a microchannel distillation unit, the microchannel distillation unit comprising a plurality of microchannel distillation sections, the fluid mixture comprising a more volatile component and a less volatile component, the process comprising: flowing a vapor phase of the fluid mixture in a first microchannel distillation section in contact with a liquid phase of the fluid mixture, part of the more volatile component transferring from the liquid phase to the vapor phase to form a more volatile component rich vapor phase, part of the less volatile component transferring from the vapor phase to the liquid phase to form a less volatile component rich liquid phase; separating the more volatile component rich vapor phase from the less volatile component rich liquid phase; flowing the less volatile component rich liquid phase to another microchannel distillation section upstream from the first microchannel distillation section; and flowing the more volatile rich vapor phase to another microchannel distillation section downstream from the first microchannel distillation section.

    摘要翻译： 所公开的本发明涉及一种在微通道蒸馏单元中蒸馏流体混合物的方法，所述微通道蒸馏单元包括多个微通道蒸馏段，所述流体混合物包含更易挥发组分和较不易挥发组分，所述方法包括： 在与液体混合物的液相接触的第一微通道蒸馏部分中的流体混合物的气相，部分更易挥发的组分从液相转移到气相以形成更易挥发的组分富气相，部分 挥发性较低的组分从气相转移到液相以形成较不易挥发的组分富液相; 将较易挥发的组分丰富的气相与较不易挥发的富含组分的液相分离; 将较不易挥发的组分富液相流向第一微通道蒸馏段上游的另一微通道蒸馏段; 并将更易挥发的富气相流动到第一微通道蒸馏段下游的另一微通道蒸馏段。
