Abstract
Systems and methods to improve the removal and capture of oil from wastewater streams. The water and oil mixture (wastewater) is diluted and treated to provide better solubilization of hydrophilic and hydrophobic fractions using captive water and a diluent. Two additives are added to demulsify and disperse polymeric and non-hydrocarbon insolubles and layer separation is performed on the treated wastewater to segregate oil and water.
Claims20
A system for capturing waste oil, the method comprising:
- a first vessel including a wastewater comprising, oil, water, and solids;
- a first mechanical agitator for agitating said wastewater in said first vessel;
- a pump for removing a portion of said oil from said wastewater in said first vessel;
- a second vessel including a wastewater comprising, oil, water, solids, a diluent, a solvent additive, and a detergent salt;
- a second mechanical agitator for agitating said wastewater in said second vessel;
- and
- a pump for removing a portion of said water from said wastewater in said second vessel.
