Issues encountered with ASPEN calculators for packed columns
Thread Content
Today, while using ASPEN to simulate a packed tower, I found that by changing the gas-liquid load – for example by increasing the reflux – the ratio of the liquid phase to the gas phase increases. Theoretically, this should result in a decrease in the maximum capacity factor, but the software showed the opposite effect: as the reflux rate increased, the maximum capacity factor grew larger, which is clearly contrary to theory. Has anyone else encountered this issue?

In other words, even though the type of filler is specified in the software, it’s still not possible to calculate the maximum capacity factor on one’s own, or to assign a random value in order to determine the maximum fractional capacity? In that case, what’s the need for software at all? We can calculate the maximum fractional capacity ourselves based on the maximum capacity factor
