(Packed tower) Problem of segmented packing in packed towers
Thread Content
A packed tower is to be designed with a diameter of 1.5 m and a packing height of 6.8 m; it needs to be divided into sections. What are the requirements regarding the distance between these sections? PS: For the stepped ring packing, h/d=8 and h=12000 mm; is the distance between the two sections 12000-6800? Is it too big... Thank you to all the experts! ! ! ! ! ! !
It is generally classified according to the sheet specifications, 2000-----2400.

It should be installed exactly as designed by the design institute; one section is meant for distillation and another for rectification!

If both the lifting and distillation sections of the packing are considered, these two sections should be placed at some distance from each other; components such as distributors can be used in between them. If only the strength of the packing itself needs to be taken into account, a distance of around 1.5 meters between the two sections is sufficient. The main consideration is to ensure there is enough operating space between the loading and unloading ports
In a normal design, the spacing between two packing sections is around 1600 mm; this space is used to accommodate the distributor and compression rings, as well as to leave some room for the height of the packing sections.
During the technical exchange with Kefukai last time, I heard that the height of the filler segments is related to the processing method, gas-liquid distribution, and mechanical strength!
