NOVEMBER 2, 2015 — For many shipowners, Exhaust Gas Recirculation (EGR) is emerging as an attractive option for compliance with the Tier III NOx emission limits that will soon apply in the North American and U.S. Caribbean Emission Control Areas (ECAs).
Alfa Laval says that its just launched PureNOx Prime water treatment system for EGR engines operating with low-sulfur fuel gives EGR an even sharper competitive edge.
"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."
For use with low-sulfur 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 Ms. Effler. "PureNOx Prime further diminishes the EGR footprint, and it has a more modular design that makes installation even more flexible."
Alfa Laval says that the leaner design also reduces the investment cost.
What remains unchanged in PureNOx Prime is the reliable water treatment, 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 Ms. Effler. "Simply put, PureNOx Prime packs the already proven PureNOx performance into a much smaller footprint."
