Reboilers Latent heat of vaporization decreases i.e., reboiler and condenser duties become lower. Reboiler temperature increases with a limit often set by thermal decomposition of the material being vaporized, causing excessive fouling. Another variable that needs to be set for distillation is refiux ratio. For a stand-alone distillation column, there is a capital-energy tradeoff, as Get Price
️ Inter-condensers and inter-reboilers Adding inter-condensers and/or inter-reboilers can help improve overall energy efficiency. Pumparound, one of the inter-condenser concepts, has been widely applied to numerous petroleum multi-product fractionators. On the other hand, implementing an intermediate reboiler can reduce the main reboiler duty.Get Price

Reboilers are used to generate a flux of vapor to feed to a distillation tower; the vapor rises up the tower contacting a downwards-flowing liquid stream. A whole variety of forms of reboiler have been used in practice, some of which are described briefly below. General reviews of the forms and design of reboilers are given by McKee (1970), by Get Price
In chemical plants and refineries, reboilers used to heat incoming feed for distillation towers are often heat exchangers. Distillation set-ups typically use condensers to condense distillate vapors back into liquid. Power plants which have steam-driven turbines commonly use heat exchangers to boil water into steam.Get Price
