How to determine the required number of actual theoretical plates and the feed position in radfrac?
Thread Content
Given: R, D/f, theoretical plates, feed position below the theoretical plates, condenser pressure, column pressure drop, and parameters of the reboiler and condenser. Find: the actual number of theoretical plates and the feed position under the separation requirement conditions. I’ve tried for ages but don’t know how to do it; I hope some experienced folks can give me some advice.
It is recommended to start with the basics and look at specific examples; there are some on the site, so give them a try.
This requires sensitivity analysis; create a graph
It can be specified through design, but since the feed tray number changes depending on the total number of trays, a calculator is also needed to determine the relationship between the two variables.
Reply to 2# Albertlu: This question is related to the example on tray efficiency in the chapter on towers in the *Zhejiang University edition A+ course materials; I’ve tried hard for a long time but still can’t understand it. Thank you for your suggestion
Reply to 5# zyzsd: Thank you for your suggestion. I’m starting to learn the calculator used in *specified design right now.
Remember to first use DSTWU for estimation, and then use the strict tower method.
