Questions about oil-water separators
Thread Content
I would like to ask, what type of module is generally chosen for oil-water sedimentation separation? It seems the decanter won’t work; thanks!
This model seems okay, right? But to what extent does the landlord need to go? :funk: Surely they won’t provide detailed drawings of the internal components, nor will they specify concentrations in ppm, right?
A decanter can simulate mixed clarification, no problem. I wonder if the original poster is setting too high a standard.
Is the poster trying to simulate the settlement process? Aspen is a steady-state simulator and cannot calculate dynamic processes such as sedimentation velocity distributions.
Reply to 4# wuwei253273: I want to simulate the oil-water separation based on the density of the materials, specifically the sedimentation and separation process of light coal tar and water. It is necessary to determine the oil content in the aqueous phase after separation; I’m not sure if PLUS can achieve this
The separation efficiency during the actual settling process is influenced by factors such as droplet size, settling time, and viscosity, which are not reflected in the separation modeled by Aspen. Aspen calculates steady-state results; in reality, it takes a long time for the process to approach or reach a steady state, and such a situation is usually not achievable. Settlement is a dynamic process, and it is best simulated using fluid simulation software.
