De Nora’s SEACLOR seawater electrochlorination systems provide reliable and sustainable onsite cooling for coastal power generation.

De Nora has seen a 7.4% increase in demand for its SEACLOR seawater electrochlorination systems in Asia as a result of rapid economic and population growth in the region. This growth number is expected across the next five years, and De Nora anticipates that the growth trajectory will maintain as the region rapidly develops. The technology, which uses seawater as a coolant in the production process, will fuel sustainable development in the region, helping power plants, oil and gas producers and LNG terminals keep up with energy demand without losing sight of environmental goals and initiatives.
“There are clear benefits for using De Nora’s SEACLOR electrochlorination systems for cooling in coastal powerplants,” said Kurt Agricola, global product manager of seawater electrochlorination for De Nora Water Technologies. “Any solution that makes the power generation process cheaper, safer and more reliable will help countries and municipalities. Add being more sustainable to the mix, and it becomes the perfect combination. We hope our success in Asia can serve as an example as leaders in the power generation field considering supplement options to their current systems.”
As a free and renewable resource, seawater is one of the most sustainable solutions for cooling in the power generation process for coastal power plants. SEACLOR systems generate a low-concentration sodium hypochlorite by adding electrical energy to ocean water. Throughout its 40-year history of developing the technology, De Nora engineers have overcome many challenges associated with the practice, the most common including degradation, safety and by-products. Each unit is designed for continuous, unattended operation, allowing for maximum biofouling control that effectively treats hazardous marine substances. In addition, patented De Nora DSA electrodes ensure longevity in varying temperatures and chloride concentrations.
In Indonesia, the SEACLOR has been implemented at Belawan Power Plant, the largest power facility in North Sumatra with 260MW (steam) and 817MW (combined cycle) plant capacity. Systems are also planned to be rolled out to coastal power plants and oil and gas installations across the continent, including projects in Selangor, Malaysia and Kaohsiung, Taiwan. The company currently has more than 1,200 seawater electrochlorination installations in 60 countries.
