Greetings everyone. Can someone help me understand how does hydraulics work around kettle type reboilers for distillation column. From reading online its necessary to perform this calculation to set the elevation of the reboiler with respect to grade and with respect to the column.

 

Any guidance will be greatly appreciated.

 

Thanks

If you are carrying out thermal design of the Reboiler in HTRI there is a tab in the same wherein one can carry out the hydraulics.

 

You can also google to get some good resources/articles

For a new design it's best to feed the kettle from a draw tray. This arrangement will make use of the column sump capacity. You set the overflow weir about 300 mm above the sump high liquid. Maintain sufficient head from the draw tray to the reboiler baffle based on the return vapor pressure drop. Sketch the arrangement and the hydraulic calculations will be obvious to you.
