Parameter setting issues when selecting Partial-Vapor for the Condenser in the Aspen RadFrac module
Thread Content
Dear fellow engineers, I have a question: For the Aspen RadFrac module, when the Condenser is set to Partial-Vapor mode, why are two operating variables required in the Operating specifications? My understanding is that the gas phase is recovered while the liquid phase is completely recycled; but what does it mean to select a reflux ratio in this case? Does this reflux refer to the simultaneous recycling of both gas and liquid phases, or something else? Furthermore, how should the temperature of the gas outlet at the top of the tower be specified? I hope everyone will feel free to share their advice; thank you! ! !
In a Partial-Vapor tower, the heat exchanger is different from a condenser: only a portion of the vapor is condensed and returned as a liquid phase, while the gas phase is not returned and is discharged as the product
Hello, I would like to ask how to set this condensation temperature? Thank you
As long as there are a condenser and a reboiler, two regulations are required.
Here, the reflux ratio = reflux rate / distillate flow rate
The temperature of the gas stream at the top of the tower is specified through the design specifications.
