Abstract: Systems and methods are provided for separating a feedstock into a plurality of separation products using dividing wall column technology that includes a plurality of dividing walls. Including a plurality of dividing walls in the column can provide reduced energy consumption and reduced equipment footprint for production of a plurality of high purity distillation products. The systems and methods can allow for separation of a large number of products from a feed while having a reduced or minimized number of liquid splits and/or vapor splits.

Abstract: Vane type mist eliminator segments are arranged in a plurality of tiers at separate vertically spaced locations in a tower, typically of the upright, cylindrical type, with the eliminator at each tier covering only a portion of the cross section of the tower. The eliminator segment(s) in each tier are laterally displaced in the tower from the adjacent vertically spaced eliminator segments to form a staggered configuration for the segments. Each mist eliminator preferably extends over 50-70% of the cross-sectional area of the tower to leave an open flow passage in the tier; the staggering of the segments and the associated flow passages defines an upward tortuous or zig-zag open flow path for vapors ascending the tower through the open flow passages when the eliminator segment(s) become fouled in use.

Abstract translation: 叶片式除雾器段在塔中的分开的垂直间隔的位置处布置成多个层，通常为直立的圆柱形，每层的消除器仅覆盖塔的横截面的一部分。 每个层中的消除器段在塔中从相邻的垂直间隔的消除器段横向移位，以形成用于段的交错构造。 每个除雾器优选地延伸超过塔的横截面面积的50-70％以在层中留下开放的流动通道; 段和相关联的流动通道的交错限定了当消除器段在使用中被弄脏时，向上弯曲或向上弯曲的开口流动路径，用于通过开放流动通道升高塔的蒸气。
