PROII tower model RATEFRAC algorithm
Thread Content
The PROII tower model RATEFRAC algorithm is used for calculation, and built-in random packing is used. Why are the calculation results related to the number of stages of the tower? Now that the tower diameter, packing type, packing height and other parameters have been determined and the rate model is used, the calculation results should only be related to the performance of the packing. Why is it still related to the theoretical board?
I have the same question. I encountered the same problem. The tower height, diameter, and packing parameters are all given. I feel that the theoretical board is a virtual value. I don’t know why adjusting the theoretical board will affect the results. What I understand is that this theoretical board is a virtual quantity when calculating board by board. It is just a number of calculations. The more calculations, the more accurate the results will be. I don’t know if the poster understands it now.
I just found the help file in ASPEN, and it seems to me that it means the same thing, which is to discretize the packed tower and increase the number of calculations to make the results more accurate. I don’t know how the original poster understands this. Sea friends can also express their opinions on this issue that has been bothering them for a long time.
Changing the theory board will affect the calculation, and the basic data for calculation will definitely change.
