Alfa Laval PureNOx Prime cuts EGR space and investment needs
As the implementation of Tier III NOx limits approaches, Exhaust Gas Recirculation (EGR) is rapidly maturing. Now Alfa Laval has introduced Alfa Laval PureNOx Prime, a streamlined version of its EGR water treatment system for EGR engines operating with low-sulphur fuel. Smaller and leaner than its predecessor, Alfa Laval PureNOx Prime gives EGR an even sharper competitive edge.日期 2022-01-26
Many ship owners are considering their choice for compliance with Tier III NOx limits, which will soon apply in the North American and US Caribbean Emission Control Areas (ECAs). EGR is already the technology front-runner, due to its significant space savings and low total cost of ownership. But with the introduction of Alfa Laval PureNOx Prime, recently launched at Kormarine, EGR’s advantages are even stronger.
“Alfa Laval PureNOx technology has always met the strict legislative demands on EGR water treatment,” says Kristina Effler, Business Manager, Water Treatment Exhaust Gas Emissions. “With Alfa Laval PureNOx Prime, we put additional emphasis on the tough market demands of low investment and operating costs.”
Reduced footprint and investment cost
For use with low-sulphur fuel, PureNOx Prime is a highly streamlined water treatment system. “EGR is a compact technology in which most components are built into the engine itself,” says Effler. “PureNOx Prime further diminishes the EGR footprint, and it has a more modular design that makes installation even more flexible.”
Naturally, the leaner design also reduces the investment cost. “The more hours spent in ECA operation, the more economical EGR becomes,” Effler says. “With PureNOx Prime available for less, that low lifecycle cost becomes even lower.”
Technology proven at sea
What remains unchanged in PureNOx Prime is the reliable water treatment, which is a crucial aspect of EGR operation. The PureNOx technology, which makes use of centrifugal separation, has been proven in thousands of hours of real-life operation at sea.
“Alfa Laval PureNOx technology has been developed in close cooperation with MAN Diesel & Turbo and tested extensively aboard vessels from A.P. Moller-Maersk,” says Effler. “Simply put, PureNOx Prime packs the already proven PureNOx performance into a much smaller footprint.”
