The use of distillation and absorption column lining in a three-phase separator and a three-phase separator equipped with such a lining

摘要

The invention relates to the use in a separator for a three-phase liquid-liquid-gas mixture of a packing structure (Fig. 4, not shown) which is normally used in distillation columns or in absorption columns, the structure being constituted by thin fluted sheets pierced with orifices and stacked in such a way as to form channels open at their ends, the channels of one and the same sheet being offset angularly in relation to those of the immediately contiguous sheets. In separator 1, the three-phase mixture enters via pipe 2, is divided into two streams by divider 26 and passes down a sequence of steps 7. The packings are suspended from the top of the separator at 8a and 8b and suppress foaming. Heavy liquid (e.g. water) is removed via connection 4, the lighter liquid (e.g. oil) via 5 and gas via outlet 6. Further packings 12a, b, c are used to dampen resonance in the liquid which could arise from motion (e.g. or a marine installation). IMAGE
