This post was last edited by fengyuzai*an on 2011-5-12 17:25. Guys, in the simulation of a distillation column, can we set the temperature at the top and bottom of the column ourselves? Could you help me understand what the errors below mean and how to fix them? ERROR HISTORY IS NOT AVAILABLE FOR THIS ITERATION UNIT 1 NOT SOLVED - 'T1
The temperature of the condenser can be set at the top of the tower, while that at the bottom is generally determined automatically based on the tower pressure and the material system. . .
Sure, but it’s only useful if it’s defined in SPEC
Reply to 2# shan9999: Do you mean that in a tower top temperature simulation, the tower bottom temperature is automatically generated? My current task is to work with Tawain to optimize the current operating parameters. Is there any way to do that?
Well, there are many types of condensers. Generally, for subcooling, the temperature can be set; for other types of condensers, it’s usually the bubble point or dew point temperature that matters. Once the composition of the fluid and the pressure drop in the tower are determined, the temperatures at the bottom and top of the tower are also determined automatically, as it’s a theoretical model where the fluid is in a bubble or dew point state. . .
Take a look at books on chemical separation; they contain information on the calculation of design variables and operating variables, etc
