On the flooding calculation of trays in Aspen
Thread Content
When using Aspen to verify tray performance, the literature states that ASPEN PLUS provides a program for calculating the value approaching flooding for bubble and sieve trays, whereas for floating valve trays, ASPEN PLUS uses a program obtained from the supplier’s design reports. Does this mean that when using Aspen to calculate floating valve trays, the data on flooding will be very inaccurate if there is no program from the seller’s design report? Also, the person who has done similar work using aspen could share their insights. Thank you!
Aspen isn’t used to calculate flooding; I think it can be understood in this way: since bubble trays and sieve trays have a limited variety of designs, general methods can be applied to them. However, with float valve towers, there are many different types of float valves, and Aspen doesn’t have enough time to calculate each one individually, so it has to rely on the design reports provided by the manufacturers.
Does the poster have ASPEN’s program for the flooding margin value of tray towers? Could you introduce it or share it? You can send an email to: mzpyb@163.com
