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.
Claims19
A method for capturing waste oil, the method comprising:
- providing a wastewater comprising, oil, water, and solids;
- agitating said wastewater and allowing said wastewater to phase;
- removing a portion of said oil from said phased wastewater;
- mixing a diluent, a solvent additive, and a detergent salt to said wastewater after said removing to form a wastewater solution;
- agitating said wastewater solution and allowing said wastewater solution to phase;
- and
- separating a further portion of said oil from said wastewater solution.

A method for capturing waste oil, the method comprising:
- providing in a first vessel a wastewater comprising, oil, water, and solids;
- agitating said wastewater in said first vessel and allowing said wastewater to phase;
- removing a portion of said oil from said phased wastewater;
- transferring said phased wastewater to a second vessel;
- mixing a diluent, a solvent additive, and a detergent salt to said phased wastewater after said transferring to form a wastewater solution;
- agitating said wastewater solution in said second vessel and allowing said wastewater solution to phase;
- and
- separating a further portion of said oil from said wastewater solution.
