Is it possible to simulate solid separation?

This post was last edited by Zhi An. Edited on 2025-4-12 23:52. Aspen Plus v14 was used to simulate the sulfolane-based extraction process for aromatics. In the solvent regeneration unit, a high-temperature regeneration tower is required to remove impurities or acidic components from the solvent. Since there are also insoluble solids present in the solvent (such as carbon black particles or metal sulfides), a solid separator is needed afterward to separate solids from the liquid. Which module would be suitable for this solid separator: Sep or CFuge? Additionally, since these solid components are not initially included in the component list, is it possible to monitor the effectiveness of solid removal during the simulation? Help needed
When using Aspen Plus v14 to simulate the extraction of aromatics using sulfolane, the Sep module or the CFuge module can be selected for the solid separator. Which specific module to choose depends on the actual process requirements and design. 1. The Sep module is mainly suitable for simple separation operations, such as gravity separation, where the parameter settings are relatively simple. 2. The CFuge module is specifically designed for simulating centrifugal separation operations, and is more suitable for handling mixtures containing fine solid particles. This module allows for detailed setting of parameters such as rotation speed and pool depth, meeting the needs of complex operations better. If the solid particles involved in your process are relatively small, or if the solid-liquid mixture is difficult to separate, it is recommended to use the CFuge module. If the separation process is relatively simple, or if the solid particles are large and easy to settle, the Sep module can be used. As for monitoring the removal efficiency of solids, although no solid components were included in the initial mixture, it can be simulated in Aspen Plus by adding hypothetical components or tracking the generated impurities. During the simulation, the generation, consumption, and separation processes of these components are set, thereby enabling the evaluation of the effectiveness of solid removal. It is essential to ensure that these assumed components accurately reflect the properties and behavior of solids in actual operations. In the simulation settings, various parameters need to be carefully adjusted to ensure the accuracy of the simulation results. .
