Thermosiphon reboiler principles
Did you know?
Thermosiphon (or thermosyphon) is a method of passive heat exchange, based on natural convection, which circulates a fluid without the necessity of a mechanical pump. Thermosiphoning is used for circulation of liquids and volatile gases in heating and cooling applications such as heat pumps, water heaters, boilers and furnaces. Thermosiphoning also occurs across air temper… Webb4 maj 2009 · I have designed thermosyphon reboilers with as low as 10% vaporization to as high as 50% vaporization. In a demethanizer reboiler, where the reboiler feed has all components from Hydrogen to C5 Hydrocarbons, the reboiler is designed for as low as 10% vaporization.
