Hi All,
I want to wash plastics stream (solid) using a CCD or a SWash column in Aspen Plus.
My feed flow rate = 10,000 kg/hr, Mixing efficiency = 0.9, and liquid to solids ratio = 2.
I am using water incoming flow rate of 20,000 kg/hr.
Yet, once the simulation is run, it sends all the flows i.e., water + feed (30,000 kg/hr) to come out from the top of the column. Nothing comes out from the bottom.
Note that I have specified PSD for solids and all seems to be fine.
Can somebody help in understanding me how Swash or CCD column works? What should I do to achieve a liquid (top) and solids (bottom) separation in Aspen Plus?
Appreciate your guidance.
Best,
Geetanjali
