Hello everyone,

 

I would like to ask a question regarding the sizing and design of a hydrocyclone that separates solids ranging from 25 microns to 900 microns in a liquid flow. 

In a perfect world, i would prefer any solids smaller than 100 microns going to overflow and any size bigger than 100 microns going to underflow.

Criteria to meet: Overflow flow rate will be in a range of 30-50 imperial GPM. 

Underflow needs to be above 20 Imperial GPM to ensure the line is not plugging off. I understand there is a best practice for overflow/underflow ratio (4/1), but it is too risky to plug off the lines. 

 

The solids are salt crystals ranging from 100 microns to 900 microns and CaSO4 crystals ranging from 25 to 75 microns. I am unsure what density value I should use to calculate Dpc 50? The bulk density (1260 kg/m3) or salt particle density (2160 kg/m3)?

I do find an excel sheet that has built in model to do the sizing, but i am unsure if it is accurate. I attached it below. 

 

Any advice are highly appreciated. 

Thanks,

Jordan

No spreadsheet attached.  To attach the spreadsheet, click "Edit" the original post (OP), click "Use Full Editor", and use file attach functions, which are below the text box.

Thank you! Just attached the file.

Never use any software that you have not validated. Excel is the worst! You should prepare specs and send to vendors for sizing.

Hi,

Your document is related to a cyclone for the separation of solid from a gas stream, not a hydro cyclone.

Please consider these links:

Many more using your favorite search engine.

 

As suggested you may want to prepare a spec sheet and submit it to vendors to get a proposal (design and cost).Make sure you are familiar with PSD of your feed and expectation from this equipment.

Good luck
