    Vapor Disengagment: Sump volume vs self venting pipe?

    It looks like the vent from the buffer tank goes below tray T3 when the drawoff comes from above T3. There is a pressure difference (equal to the pressure drop on the tray) that may hamper liquid flow. A dip leg in the buffer tank would help.

    Did the Romans have engineers?

    What about organizational and project engineering skills required in such huge and time-lasting projects as the building of cathedrals, bridges, pyramids... How did ancient "engineers" coordinate workers, mobilize resources, etc. ? I would be interested if anyone had references about the history...
