next stage, and rods or shed decks can be substituted as the contacting devices. The
use of structured packing has been reported with excellent results. Lower steam
usage, better contacting, and utilization of almost the entire cross-sectional area of the
stripper are benefits seen with the new designs. Horizontal trays with small holes
configured as distillation trays have been tested in the lab and have been put into
service in the field. A few of the commercial packing designs are shown in Fig. 14.
