Hello
I have designed a standard kettle reboiler, but i don't know how to calculate the static head. When can we design trapout kettle? what is difference between static head calculation of these two type kettle reboilers and their head static?
In addition, I have designed six internal reboilers for the vacuum condition. Please help me about design guidelines, for example the position of the reboiler in the sump of a column.
Thanks in advance

What do you mean exactly with "static head"?...
My guess is that you have a column and you're trying to calculate the pressure that the column bottoms will have when they reach the reboiler, is it correct?
In this case, you should have some data about the height of the liquid in the column bottom considering internal baffles, as well as the liquid density and the pressure inside the column.

There are two parts to the static head in a kettle reboiler. The first part is between the inlet of the reboiler and the boiling surface. The density used is for a two phase mixture.The second part is from the boiling surface, through the return line and back down to the liquid surface in the tower. The density used is the outlet vapor density.
