Acids generally break emulsions more effectively than coagulant salts, but the resultant ,acidic waste water, must be neutralized after oil/water separation. As described above, metal ions, such as, Fe 3 +, Zn 2 +, Al 3 +, etc., have long been used to break oil-in-water emulsions, but recent government regulations have restricted their levels in discharged streams.

FTIR deconvolution elucidated that the acid media could improve the availability of urethane groups to participate of ,demulsification, process. Results also showed that the foam has a maximum oil adsorption capacity of 541 mg g−1 at pH 6 the turbidity removal from metalworking fluids by p-PUF was of 86% while at pH lower than 4, turbidity removal was higher than 99%.

Simple demulsification can be achieved by using a technique referred to as Acid-Cracking. By reducing the pH of the wastewater to a range between 2 and 4, the free oil will separate and rise to the surface of the oil water separator. Ellis engineers have responded by designing the Emulsion Breaking System (EBS).

Effect of Demulsification for Crude Oil-in-Water Emulsion ...

Acidic, substances (naphthenic acids) were found in crude oil, which provides favorable conditions for the formation of surfactants. N,N-Dimethylcyclohexylamine (DMCHA) can activate the naphthenic acid in the crude oil to form the surfactant by noncovalent bonding. This process has an unusual meaning for the crude oil pipelines transportation by the method of forming a low-viscosity oil-in ...

Chemical demulsification methods such as adding acid, alkal and inorganic salt were employed. The results showed that for Emulsion System A, the best way for demulsification was ultrasonic 30 min, 80 KHz sound intensity, 70°C ultrasonic temperature. The demulsification rate could reach 46% and concentration multiple of rare earth ions was 2 times.
