DE NORA DELIVERS ClorTec SYSTEMS TO PERMIAN FRAC SITES
De Nora, a leading designer of safe, innovative, and sustainable water disinfection and oxidation, filtration and electrochlorination solutions, has completed delivery of eight ClorTec mobile disinfection systems to treat frack water at different sites in the Permian Basin. As part of the hydraulic fracturing process to release onshore oil and natural gas from shale, water must be disinfected shortly before going downhole to prevent growth of anaerobic, iron-consuming bacteria and other microorganisms. De Nora worked in conjunction with its partner, Neptune Solutions Company to provide fully equipped disinfection trailers, each with a ClorTec CT-DN on-site hypochlorite system, tanks, dosing pumps, analyzers, HVAC and a small lab. Each containerized system has the capacity to generate up to 1,500 pounds per day of a 0.8% sodium hypochlorite disinfection solution, a chlorine equivalent, using three common consumables: salt, water and electricity. This is sufficient to treat upwards of 235,000 barrels of frack water per day, per unit.
Since 1995, ClorTec on-site sodium hypochlorite generation systems have been designed, delivered and installed to disinfect municipal drinking water and industrial process water at more at than 3,500 sites around the world. De Nora’s most recent electrochlorination innovation, the ClorTec DN unit used in the trailers offers simple operation and maintenance as well as performance and safety advantages and employs De Nora DSA bipolar electrodes for highly efficient salt and power usage.
De Nora’s initial collaborations with Neptune Solutions Company include a produced water recycling center, which currently treats upwards of 500,000 barrels of produced water per month – which has immediately been used in well completions – and has been in operation since last year.
Generating disinfectant on-site produces a less hazardous hypochlorite solution than bulk hypochlorite and eliminates the need to transport hazardous materials. Additionally, on-site provides protection against chemical price fluctuations and avoids costly chemical containment systems and risk management planning. The unique design of the ClorTec DN electrode/cell rapidly and effectively removes hydrogen, the only by-product generated by the system. (Source: De Nora – Image: Neptune Solutions)
