How is the internal diameter of a small packed distillation column with a size of 10–30 cm calculated? Does it mean that the filler to be chosen must be determined first? Can the internal diameter of a tower be calculated using a plate tower? Looking forward to expert answers, thank you
Such a small tower can only use packing; indeed, different types of packing result in different tower diameters, and thus the tower height also changes – all these factors need to be taken into account
It should be possible to determine the tower diameter first and then choose the filler, as laboratory fillers are available in specifications ranging from 3mm to 15mm. For inquiries regarding fillers, please contact me via QQ: 172785339
The inner diameter is determined based on the production volume of the product you need to obtain ； For such a small device, investment costs shouldn’t be a major concern; the key is whether the separation performance can be achieved. As for the parameters, it is necessary to determine how many theoretical plates are required for the system you want to separate, and then take into account the type of packing used; different packings result in different numbers of theoretical plates ； Then determine the tower height. Generally, due to height limitations in small tower installations, it is more common to choose a circular or triangular packing; these are types of packing that result in a particularly high number of theoretical plates. If a lower total number of theoretical plates is required, it is recommended to use regular packing.
