How to write energy balance for a tube and shell condenser?

Hi all,





I have some problems writing the energy balance for a tube and shell condenser. The goal is to reduce the water content of a flue gas by condensation. Cold water is used as the the cooling agent in the shell side.|||You will need to fully understand the thermodynamics of the flue gas stream to arrive at an answer. Your flue gas may be super heated or may be at saturation. You will also need to recognize that a majority of the heat transferred will be due to condensing the water vapor.





You should do a web search for data and information on flue gas properties. Below is one example of the type of information that may be helpful.|||Basically, I think what you have to do is calculate how much energy you need to cool down the water in the flue gas i.e. to get it below 100oC (or 373K). Using the equation:





Q = GcT





where G = mass flowrate


c = specific heat capacity of liquid


T = change in temperature


Q = rate of heat transfer





I'm not quite sure of this though. Check out the website in the 'source' section, cause it has references and recommended handbooks. :)
