    Oily water separation.

    That sounds like sound advice, I hope to do that. So far I have not been able to make contact with anyone. I sent an email to them requesting a contact so I'm sure they will sooner or later. I tried calling but was not able to get anyone. They must be really busy.

    Oily water separation.

    We don't have a DAF but some sort of separator and the results are similar. I think it is basically the same stuff. I did just find this website and I'd like to know if anyone reading this ever tried one of these separators? http://www.pall.com/datasheet_chemical_40422.asp?sectionid=performance

    Oily water separation.

    At the temperature found in a crude column (600 F range )much if not all the chlorides will disassociate and go overhead as single chloride ions. They become HCl in the ovhd. I am not sure what temperature the disassociation occurs at. You are talking about 1/2 the temperature so the chlorides...

    Oily water separation.

    That sounds like fractionation to me. I guess if you do it at low enough temperatures that you don't break down the chlorides it might work. In a normal crude tower you would get the chlorides breaking out going ovhd and salting off and corroding everything. What temperature does it operate...

    Oily water separation.

    As little as 10% oil to as much as 90% oil is what I have seen and but usually around 40% to 50%. I can see one problem with evaporation. I need to desalt this material so it can by-pass the desalter and I don't see evaporation doing that. If you run it back through the desalter it just makes...

    Oily water separation.

    Wouldn't evaporation be very energy intensive? I guess there isn't that much slop so maybe it would be ok. Do you have any details?

    Oily water separation.

    I am currently dealing with this problem. The emulsion generated by the desalter is so tight that it makes a mess out of the waste water treatment plant. I do not believe an ordinary gravity separator will touch this stuff. We have about 50 frac tanks of this stuff paying $1000 per month for...
