Does ASPEN’s built-in diameter calculation program for Nutter Float Valve trays take into account operational flexibility? Some columns require a flexibility of 110%; should an over-design factor of 1.1 be specified in such cases? However, the column diameter calculated in this way turns out to be larger than those actually used in practice. Why does the number of passes have no impact on the calculation of the column diameter?

It is recommended to use professional hydraulic calculation software, such as those from TG and Sulzer; chemical simulation software provides rather rough results, with even less accurate representations.

Reply to 2# LTY: Hello, what is TG for? I tried searching on Baidu but couldn’t find any information. Thank you
