Emulsified oil in wastewater

Emulsified oil may be contained in the wastewater from the desalter unit of the refinery.

The emulsified oil in the wastewater is not easy to separate. When the emulsified oil is pumped into the oil tank and then pumped into the refinery, the emulsified oil will affect the relevant units indefinitely.

Any ideas or tips to stop the emulsified oil in wastewater?

1. There are several proven technologies to treat and infact recover emulsified oil in a concentrated form. This include Ultra Filtration (concentration and recovery ) , Advanced Oxidation processes like Photo Chemical Oxidation , Ozonation 

    

2. Resourcsextract has two unique technologies for effectively removing oil and particulate matter from waste water.  ReXtract ElectroWave technology can reduce the oil to the PPM range.

   1. could you kind offer more message for the technology? 

3. We have had good success oxidizing emulsified oils with our TITUS Twister mixing aerator with ozone enhancement. lewis@titusig.com

   1. we hope the oil could return to process.

5. bonjour votre post mérite quelques explications 

   vous parlez d'eaux usées mais de quelle production sont elles? 

   ensuite cette huile d'ou provient-elle?

   est ce une huile alimentaire, une huile hydrocarbure?

   qu'elle est la vraie problématique de votre post: le traitement définitif des eaux usées, la destuction des huiles, le rejet en fin de traitement ?

    

   hello your post deserves some explanations

   you talk about wastewater but what production is it?

   then this oil where does it come from?

   is it a cooking oil, a hydrocarbon oil?

   what is the real problem of your post: the final treatment of wastewater, the destruction of oils, the discharge at the end of treatment?

   1. the oil is the ​hydrocarbon, come from the refinery. the best is to separate the oil and wastewater, then the oil could return to process.

6. Hi Lin, you need an advanced oxidation chemical treatment to break these molecules and separate the oil. Electro-coagulation is the appropriate technology. Skimmer will only remove the free oil.

   1. could the coagulation agent, act as the performance of Electro-coagulation?

7. Use oil dispersent & then separate oil from water with help of oil separator like oil skimmer.

   1. the Emulsified oil in funnel during 7 days can not separate, any agent suggest to speed up?

8. Lin, we have O&G congenital and wastewater treatment experience, please let me your email to share you some confidential proofs we have regarding refinery process experience for safe water ground re-injection and re-use.
