Method of Removing Oil and Heavy Metals from Petroleum Produced Water Using Microbiological Stimulation Coupled to Dolomite Filtration

BACKGROUND The production of conventional and unconventional oil and gas resources is accompanied by the production of large volumes of produced water (PW). PW contains high concentrations of total dissolved solids (TDS) and oil. TDS of PW includes high concentrations of toxic metals (e.g., Ba, Sr, Cd, Cr, and As). Oil includes dissolved and emulsified...

A Method for Dissolved Gas Separation

Surfaces are engineered to be non-wetting, by coating with hydrophobic material for aqueous solutions Surfaces are engineered to be non-wetting by coating with an oleophobic material for non-polar hydrocarbon based fluids Benefit By using non-wetting coating materials, bubble nucleation is enhanced. Once bubbles are formed, they can be eluted...
