Systems and methods for waste oil recovery

摘要

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.

主权项

1. 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.
