CY 700 type DN 800 mm * 12000 mm height wire mesh structured
packing
1. CY 700 type DN 800 mm * 12000 mm height wire mesh structured
packing used in distillation column.
It is an typical distillation packing. The tower internal diameter
is 800mm. And the packing beds are totally 12000 mm. So we will
need to make 60 layers of CY 700 wire mesh structured packing
pieces for this tower.
2. What are the necessary structured pacing conditions for CY 700
type DN 800 mm * 12000 mm height wire mesh structured packing?
1) The surface area per unit volume of structured packing should be
large;
2) The free volume of the liquid phase in contact with the gas
phase must be large;
3) The resistance to steam should be small (i.e. the
cross-sectional area of the gap should be large);
4) Chemical resistance to both liquids and vapors;
5) The density should be small;
6) The price per unit of effective area should be small
