Abstract: An oxidizing composition for removing hydrogen sulfide (H2S) from a gaseous or liquid stream includes mixture products of water, sodium hypochlorite, a chelating agent, and a transition metal compound. The chelating agent can be etidronic acid; the transition metal compound can be an iron (III) compound, such as ferric sulfate. The oxidizing composition is formed by (i) combining water, chelating agent, and transition metal compound to form an activator composition and (ii) mixing the activator composition with a sodium hypochlorite solution to adjust the pH, such as for a particular use. Some embodiments include various apparatuses and methods for treating different treatment sites with the oxidizing compositions disclosed herein. Examples of suitable treatment sites include, without limitation, natural gas pipelines, bubble towers, oil wells, gas wells, sewer wet wells, air scrubbers, saltwater disposal pipelines, and saltwater disposal wells.

Abstract: Waste water is remanufactured with ozone in a series of mixing vessels. The ozone is dispersed to both a top and a bottom portion of each mixing vessel, but in different amounts. This creates an electrical potential difference across the height of each mixing vessel which significantly improves the oxidation of organic carbon-based impurities and eliminates H2S and bacteria. Sludge and solids floating to the top of each mixing vessels are removed, as well as sludge and solids settling to the bottom of the mixing vessels. When oil and gas well waste water is treated in this manner, the resulting treated water is purified and has a high salt content suitable for oil or gas well injection.

Abstract: Disclosed herein are compositions and methods for increasing recovery, or flowback, of hydrocarbon compounds from hydrocarbon-containing subterranean fractured rock formations (tight shale reservoirs). The flowback compositions include an anionic dimer surfactant, an anionic monomer surfactant, and a demulsifier. The flowback compositions convert oil-wet rocks to water-wet, yet exhibit a low tendency of composition components to sorb to the rock. The flowback compositions do not cause formation of emulsions with hydrocarbon compounds within the subterranean fractured rock formations. The flowback composition are useful for increasing the yield of hydrocarbons recovered from tight shale reservoirs.
