Hi,
I have just been working on a simluation where I have seen the temperature decrease across a reboiler even though the liquid feed is being partially vaporized. So there is both sensible heat and latent heat involved, but the temperature in the reboiler outlet is cooler. The column is an Amine regenerator. The DP across the reboiler is 2psi. Has anyone ever encountered a temperature decrease across a reboiler and if so why is this happening?
I hope you can help.
Many thanks,
CM
