Diesel washing (flushing) with water to remove dissolved brine

joisy · Jul 6, 2003

1) Has someone experienced with the flushing of the diesel with portable water and follow-up separation (via centrifuge) of the dissolved water to delute and remove the soluted sodium hydroxide? We use the bubbling method!

2) How it can be better achieved: to add dimulsifier to diesel and wash with or to wash first and then add dimulsifier?

Thanks everyone beforehand!

Joisy,

You can't remove a dissolved substance by ordinary centrifuging. What exactly do you want to do? I guess you would like to recover the sodium hydroxide from the emulsion left after washing the diesel. So you add the demulsifier to that and centrifuge out the oil. This should leave you with sodium hydroxide solution. Don't put the demulsifier in the engine itself. That's where you want to form the original emulsion to remove the oil deposits isn't it?

We want to remove the residuals of sodium hydroxide via the mixing it with water by bubblung of air, and then to add demulsifier and centrifuge the water out.
