Hi all,

 

Please can anyone advice me about number of parallel cyclones due to high pressure drop for Hydrocyclone HYSYS simulation. 

.... what defines the minimum pressure drop requirement for single cyclone for a particular underflow size and vortex finder

.... Can anyone suggest any technical material on hydrocyclone simulation using HYSYS. The HYSYS manual and help do not seem to give any details on number parallel of cyclone - pressure drop relationship

 

I am trying to implement dewatering of a low concentration slurry  (solid of around 10 to 20 microns) 10 wt%  to achieve up to 50 wt% slurry on HYSYS with low cyclone diameter of 25mm, feed flowrate at high pressure 5MPa. 

 

... Please any comments on achieving this on HYSYS

I would not use HYSYS for such an application. Look to vendors for information.

Thank you Bobby. 

I actually have implemented it on HYSYS but the challenge is that it suggests multiple number of cyclones with low dewatering efficiency. I am yet to understand the multiple number of cyclones - pressure drop relationship and the basis used by HYSYS.

Hello All,

 

Mojimee - cpould you please share you Hysys file with me. I am trying to model a de-sanding system on hysys and I am trying to understand what fluid package (s) and how I can enter the sand composition on hysys. As I start, as far as I know hysys is VLE simulation program and it will difficult to simulate solid systems on hysys and I would like to find out how you managed to do it on hysys.

 

I´ll appreciate your help on that.

 

Regards,

Luis

Hi Luis,

 

I would not use Hysys for de-sanding. But for a slurry that can perhaps be defined hypothetically. I will suggest you refer to vendors for information as Bobby suggested.
