REBOILERS. 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 Get Price
