How to determine the height of a packed tower
Thread Content
For a small packed absorption tower, the calculations show that the tower diameter is 600 mm and the packing height is 900 mm. What is the total height of the tower? How to determine it?
Including the distributor, collector, and feed inlet, for a tower of 600 mm in height, flanged towers are generally used, eliminating the need for manholes. The height of each of the distributor, collector, and feed inlet sections can be set at 70 mm.
So, based on the most conservative calculations, how much lower can the total tower height be?
(1) First, use PROII or HYSYS to perform calculations in order to obtain values such as the theoretical number of theoretical plates. (2) Then, use pcpc (in Chinese) to calculate parameters such as the packing height, tower diameter, and pressure drop. Download of pcpc: http://www.htcsoft.com/pcpc.zip
For a 600mm tall tower, the packing layer is only 900mm, less than one meter; one section is sufficient. The top of the tower should have a liquid distributor as well as a vapor space; it is estimated to be 600–1000 mm. The bottom of the tower requires a liquid residence time of 5 to 10 minutes as well as a space for vapor-liquid separation; this needs to be calculated to determine it. The tower is estimated to be over 3 meters tall.
