Minimum residence time in a reactive distillation column
Thread Content
Is it necessary to refer to experimental results in order to determine the minimum residence time in a reactive distillation column? If Aspen is used for simulation and the residence time needs to be specified, what assumption is made regarding the holdup value in Aspen for kinetic models – that it is infinite or something else?
It mainly depends on what type of tray or packing is used. This residence time refers to the time that the liquid stays inside the tower, and it serves as a parameter for calculating reactions. It doesn’t seem like we need to enter holdup aspen in the kinetic equations, right?
The residence time is generally difficult to determine, but the holdup of the catalyst or filler under specific operating conditions can still be estimated; by knowing that, the residence time can also be ascertained. I don’t understand your last sentence
