How does the radfrac module in Aspen specify parameters related to the reboiler?
Thread Content
For the CO2 capture system using alcoholamine solutions for absorption, I would like to investigate the optimal reboiler temperature at different reboiler pressures, with the optimization determined based on criteria such as carbon capture efficiency. I would like to ask: I have selected a configuration in the Radfrac module that includes a condenser (with both vapor and liquid phases) and a reboiler of the kettle type. How should the pressure of the reboiler be specified? I couldn’t find a place to set the reboiler pressure or temperature. For example, I want to find out how the reboiler temperature at 1.5 bar/1.6 bar/1.7 bar affects various system parameters; I hope experts can offer some advice.
Given the operating pressure at the tower top, the reboiler pressure can be indirectly set in the software by specifying the overall pressure drop across the tower
