Heat transfer coefficients of several devices in flue gas decarbonization
Thread Content
For flue gas decarbonization, simulating absorption and desorption processes, what are typical values for the heat transfer coefficients of the condensers and reboilers in the flash tank and regeneration tower? ? Also, what should the pressure in the flash tank be set at? ? This post was last edited by ldklidekai on 2009-3-6 09:39]
If the pressure inside the absorption tower is 1 atmosphere, the pressure in the flash tank must be less than 1 atmosphere. First, you need to understand the purpose of a flash tank; it is used to flash a liquid at a certain temperature under low pressure, causing the liquid to boil and some vapor to be produced, which in effect concentrates the liquid. If several flash tanks are connected in series, the pressure should decrease step by step
What are the typical heat transfer coefficients for the condensers and reboilers in the flash tank as well as the regeneration tower?
