Salt Water Separation
Salt Water Separation
(OP)
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?





RE: Salt Water Separation
We always used some sort of centrefuge/ oil water seperator to 'clean' the fuel prior to use in the main engines ect.
I really cannot think of another solution.
RE: Salt Water Separation
Adding to Magnetchief's recommendation, you might want to consider use of an appropriately chosen demulsifier to further enhance the kerosene/sea water separation through either a centrifuge or oily water separator.
Ge Betz, Nalco, Baker-Hughes among others can help you with this.

We set up the float such that oil would make it float up but water would not cause the switch to operate. Inshort a specific gravity type of switch.
Hope this helps.
RE: Salt Water Separation
Probably the best way is to just drain the pipe section into a tank, let it rest and separate---then decant the water off the bottom then run the fuel thru a passive in-line fuel separator which is a cyclonic type device (with no moving parts) that runs off of existing pump pressure and drops out water and dirt.

Flight Refuelling Ltd (don't be fooled by the name) manufacture a ceramic membrane bilge water separator that will handle emulsions and is certified to the latest IMO spec MEPC.107(49) - not cheap but very low through life costs.

- not dropping the pipe in the water
- terminating the pipe with self- closing connectors
- blowing compressed air into the pipe when not offloading
