30% Higher Capacity Advanced Column Distillation Packing 452Y
1. Column Distillation Packing 452Y Introduction:
452y corrugated packing is a kind of regular packing with low
pressure drop and higher flux. The porosity is 97%. The pressure
drop of each theoretical plate is 30-50% lower than that of the
normal stainless steel orifice corrugated structured packing, and
the liquid holding capacity is about 8% - 15% of the packing
volume, The minimum liquid load is 0.2m3 / (m2 · h), and its amplification effect is not obvious.
2. Difference between 450Y and Column Distillation Packing 452Y
The difference between 452y structured packing and normal 450y
orifice corrugated packing is that 452y corrugated packing has one
more straight edge. It is this structural change that makes the new
type of 452y structured packing has more processing capacity and
lower pressure drop than ordinary stainless steel corrugated
packing. This is why more users choose the new orifice corrugated
structured packing.

5. Column Distillation Packing Specifications and characteristics
- Stainless steel orifice corrugated packing is a number of
corrugated plates pressed from stainless steel strip, which are
vertically stacked and assembled into a disc-shaped structured
packing according to the requirements of a certain diameter. The
corrugations of the adjacent corrugated plates are inclined in the
opposite direction, and the corrugations of the upper and lower
adjacent packing plates are 90 ° crossed.
- Before the corrugated plate is pressed, it is necessary to punch
holes on the plate in advance and press the fine grain, or use the
rolling grain equivalent to the fine grain.
- Eight types of stainless steel orifice plate corrugated packing are
listed in the table. The characteristic parameters of the type
selection are the specific surface area of the packing and the
angle of the corrugation, which can be selected according to the
process design requirements.
Stainless steel orifice corrugated plate
h: corrugation height (mm)
