The diameter of the distillation tower is rounded off
Thread Content
I am designing a distillation tower, and the diameter calculated for it is quite small, at just over 200 millimeters. Is it necessary to round it up to 400 millimeters?
If the calculations are correct, it’s necessary to consider amplifying the scale. The internal structure of the tower also needs to be taken into account. Besides, for a tower over 200 mm in size, how can its internal structure be installed?
It can be rounded off, but it isn’t necessary to round it to 400; an inner diameter of the seamless tube that is close to the calculated value and not smaller than that will suffice. For example, seamless tubes with diameters such as DN250 or DN300 can be used for the tower structure.
For such a small tower, I’m not sure whether you calculate it manually or through simulation; it mainly depends on the moisture level you determine. For towers with a small diameter, the diameter of the seamless steel pipe is sufficient.
First, one should consider the purpose~~~The suggestion from above is good. The key lies in how to arrange the appropriate internals to ensure the separation efficiency of the tower; the tower diameter is merely a reflection of the load~~
It’s impossible to install it; even installing a tower with a diameter of 400 is difficult. As for how to manufacture the tray, if there are liquid distributors, just one of them takes up 1/3 of the space. The gas resistance is too high, which is why towers rarely have a diameter of less than 400–500 mm
I work on packed distillation columns, and the column diameter is calculated using data simulated with Aspen. The calculation results also seem off to me. Over 200 millimeters is indeed too small! Are there towers with such a small diameter?
In fine chemical engineering, many small columns have a diameter of 200–400 mm; in such cases, a θ-ring with a diameter of φ16 or other small laboratory-type packing materials can be used.
Towers ranging from several dozen millimeters to several hundred millimeters are common in the fine chemical industry; those around 200 millimeters in size can also be equipped with structured packing.
We have used packing towers with a diameter of 250; simply using seamless pipes works just fine
Excuse me, sir upstairs, how tall is a 250mm packed tower?
