Salt Water Separation from Kerosene

[pepei]

I am trying to find a suitable solution to a marine barge offload application. The offload pipe is often flooded with salt water between offloads, and the client uses a truck to dump the first pipe volume of salty mixed fluid. They want to somehow save as much kerosene as possible during this process. Aside from a oil/water separator, is anyone had exeprience with this type of situation?

I'd have to start with investigating a way to keep the pipe from being flooded in the first place. Can that be done, perhaps with a check valve and/or pinch-type valve?

If not, second choice would be to devise a purging system using compressed air and maybe some sort of pig...

What size is your pipe, how long, and what sort of elevation changes does it course thru? More data gives better answers in the fora....

Could a pig traverse the pipe ahead of the kerosene?
