De Nora announces SWEC solution to biofouling

SANILEC TRP GOOD WEBGlobal sustainability technologies provider De Nora has launched the SANILEC TRP low-maintenance seawater electrochlorination (SWEC) system for marine biofouling prevention in offshore oil and gas and coastal applications

Powered by a new self-cleaning cell technology, the SANILEC TRP system improves safety and efficiency while minimising operating expenses. 

The damaging impacts of marine biofouling, including environmental and economic consequences, are of particular concern for offshore production facilities. Marine growth can reduce a firewater or cooling system’s efficiency, leading to equipment damage, compromised safety, and unexpected maintenance costs. 

SWEC systems use a simple electrolytic process, combining two standard consumables (seawater and electricity) to safely generate a critical hypochlorite solution. Like other similar technologies, prior De Nora electrodes have required chemical cleaning to maintain and extend their service life. The new patented self-cleaning cell technology in the SANILEC TRP unit eliminates the need to purchase, store, and handle hazardous chemicals for system maintenance.

“We see a focus on safety and OPEX on oil and gas production facilities,” said TJ Westerhaus, business development director of De Nora Water Technologies. “The new self-cleaning cell technology, which requires no acid washing, is driving towards a goal of health, safety and OPEX advantages.”

As the world leader for SWEC systems for more than 40 years, De Nora has installed more than 400 systems in 60 countries, accounting for more than 65% percent of the world capacity. With a tradition of 100 years of electrochemistry experience and anodic coating development, De Nora designed the new SANILEC TRP electrochlorinator with the first self-cleaning cell using tubular reverse polarity for the offshore oil and gas market.
