Cyclone size and oil droplet size

Cyclone size and oil droplet size

Cyclone size and oil droplet size

(OP)
I am currently trying to design a cyclone separator to separate oil and refrigerant, ie: a vapor, liquid mix.

I have some design equations focusing droplet size as the deciding funnction, but however have no way of determining droplet size due to the preceeding compression process. (see posting 135-84502)

I would request some help on either determining droplet size or existing design equation for a cyclone. Or is the design of the device a more experienced based calulation
Notes the flow rate are relatively small.

Thanks

RE: Cyclone size and oil droplet size

As far as I concern the cyclones are used for gas/solids separation - not liquid/liquid drops. Why not to use the simple two-phase separator - there are a lot of good manuals, and this will not require the droplet size (at least for the first approach).

RE: Cyclone size and oil droplet size

Why dont you just buy one from AC&R or Temprite. They have been in the refrigeration business for a long, long time.
Each have cyclone, impingement models and the more efficient coalesing types. The learning curve needed to develope these devices and bring them to market can be steep and expensive.

Good Luck

RE: Cyclone size and oil droplet size

I'm not sure if you wish to separate and collect/ salvage both oil and refrigerant? If you just want to remove oil from the vapourised refrigerant, then you can consider using a micron filter, such as those used in air compressors to remove oil from compressed air.
