Packed towers and plate towers
Thread Content
Among those with the same equivalent number, which one has greater operational flexibility?
Let’s discuss this. Anyone can flip through a book; it’s about sharing one’s own opinions, as there is still a big difference between practical production and theory
I feel that plate towers have greater operational flexibility, with a wider operating range, while packed towers require operation at the designed gas velocity; deviating from this value makes it difficult to operate them. I recall that the operational flexibility for each plate tower during design is around 60–110
I believe plate towers have a greater operating flexibility, while packed towers require higher precision and more meticulous control!
There are many types of plate towers; floating valve trays and spray trays have relatively greater elasticity. For the same processing capacity, it seems that packed towers have greater elasticity
It should be the plate tower that has a large operating flexibility
I agree with the view from the 5th floor; plate towers have greater operational flexibility.
Let’s go extreme then; it depends on how we compare. All designs ensure no flooding. I have a champion for tray towers: the bubble tray, with an operating flexibility of over 8:1. To ensure no flooding, only a high operating flexibility is required; the bottleneck in packed towers lies not in the packing but in the distributor. As long as the height of the distributor is not restricted, I can use a 20:1 ratio. If a specified diameter is required, well, it depends; when there is an excess of liquid leading to flooding, trays with better elasticity are more suitable. If flooding is caused by an excess of vapor, then the filler should have greater elasticity.
