WebOct 24, 2024 · 1 Partial reboiler is related to that fact that most times, there is material left in the bottom of the column. This can be because you need to maintain a level of liquid because the bottom take off is a purified stream you want (as product or waste treatment input) or there is not enough area to maintain the proper amount of boil up. WebControlling the inlet valve immediately changes the vapor flow which in turn changes reboiler pressure & the heat transfer rate. On the other hand condensate outlet valve has no direct influence on vapor flow rate. Condensate flow determines the condensate level & this level changes slowly.
WebNov 8, 2014 · Kettle ReboilerIn this type of thermosyphon reboiler circuit:n Liquid flows from the column sump to the bottom of the kettles shell. It is partially vaporized. The domed top section of the reboiler separates the vapor and the liquid. The vapor flows back into the tower via the riser. WebNov 10, 2024 · October 18, 2024.
