WebThe reboiler is a device that provides heat to the bottom of the distillation column, where the liquid mixture is boiled and the vapor rises up the column to be condensed and collected. The reboiler is typically located at the base of the distillation column, and it is used to re-vaporize the liquid that has condensed at the bottom of the column. Web19 de jun. de 2012 · The reboiler heat duty can be generally broken down into components of heat: the sensible heat of the solvent, the heat of reaction to release chemically bound CO2, the heat of vaporization to adequately regenerate the solvent, and the heat of reflux, which is usually negligible, to reheat the condensed reflux back to the reboiler …
