What about the pressure drop and outlet temperature in the condenser design of Aspen?
Thread Content
As the title suggests, the condenser requires input for inlet and outlet temperatures as well as pressure drop. What determines the values that should be entered for these parameters? Because different inputs necessarily lead to different results? Does the pressure drop need to be calculated first? What about the outlet temperature?
The pressure drop in typical heat exchangers is 20 kPa. Based on experience and chemical engineering design manuals, the outlet temperature should be that required by your process; generally, the temperature difference is above 20 degrees
Does that mean different condensers have the same settings?
The settings can be adjusted according to your specific needs; for example, if you know the heat transfer rate, or the temperature difference, or the outlet pressure
If it is a simulation, there is no need to enter inlet and outlet values; both the design and calculation modes require such inputs, depending mainly on what kind of simulation you are performing.
If the design and calculation models require the input of pressure drop, how is this pressure drop determined?
Is it all this data? There must be differences, right? It’s probably related to both the flow rate and the viscosity of the substance. Also, are there any differences between cooled liquids and gases?
