Cl₂/UV AOP treatment processes are highly complex and dependent on a number of water chemistry and treatment process parameters. With over three years of direct experience, MIOX is in a unique position to apply its expertise towards customer-specific optimization of Cl₂/UV AOP treatment processes with the goal of reducing costs and improving safety. The use of MIOX’s On-Site generation systems, which produces aqueous chlorine from non-hazardous sodium chloride brine, offers a safer and superior chemical introduction into AOP treatment trains compared to concentrated hydrogen peroxide or bulk hypochlorite.
“Produced water” is the oil and gas industry term for any water that comes out of the oil or gas reservoir as part of the production process. Oil reservoirs often contain large volumes of water, while gas reservoirs typically have smaller quantities. Sources of produced water include:
The physical and chemical properties of produced water are not consistent. Variation depends on factors such as reservoir geology, hydrocarbon composition, geographical location, and water injection history.
Produced water contains contaminants that require removal before proper disposal or reuse. Some of the impurities or substances likely to be found in produced water include: oil, naturally occurring radioactive materials (NORM), waxes, greases, sand, scales, dissolved salts, CO2 (carbon dioxide) and H2S (hydrogen sulfide) gases, hydrocarbons, production chemicals, and various metals.
The treatment of produced water will differ according to the intended disposal method or reuse purpose. Filtration, cyclonic separation, flotation, and evaporation are among the commonly used treatment techniques.
Post-treatment, there are a number of options available for disposal or reuse, each of which will have different water treatment criteria associated with it:
Due to increasing environmental awareness and regulations, disposal to surface waters and evaporation ponds is becoming less prevalent. Produced water is considered an industrial waste, subject to standards defined and issued by the U.S. Environmental Protection Agency.
