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 ...

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).
