What is a thermal regeneration tower in Aspen typically?
Thread Content
Aspen Plus V14 was used to simulate the sulfolane extraction process for aromatics. In the solvent regeneration unit, a heat regeneration tower is required to remove impurities or acidic components from the solvent through high-temperature treatment. Since there are also insoluble solids present in the solvent, a solid separator is used subsequently to achieve solid-liquid separation. Which module should be selected for this heat regeneration tower?
In Aspen Plus, the RadFrac module is generally used to simulate thermal regenerators. The RadFrac module can perform detailed simulations of distillation and absorption processes, and is suitable for handling liquid-gas separation at high temperatures as well as the regeneration of solvents. You need to set appropriate feeding conditions, the number of trays, pressure, temperature, and other parameters in order to effectively remove impurities or acidic components from the solvent. .
The thermal regeneration tower is essentially a distillation column; the RadFrac module is used, and there are insoluble solids present in the solvent as well, but this relies mainly on empirical data and generally cannot be calculated
