Alfa Laval – a world leader in heat transfer, centrifugal separation and fluid handling – has won the first commercial order from MAN Diesel & Turbo to supply Alfa Laval PureNOx water treatment systems to be integrated in a process to reduce harmful nitrogen oxides (NOx) emission onboard vessels. The order is worth approximately SEK 7 million and delivery is scheduled for 2013. “This is a groundbreaking order in many ways; It is our first commercial order for Alfa Laval PureNOx water treatment system and it will be integrated in a new solution on the market which fully complies with the upcoming regulations – and the order is from the world’s leading provider of low speed diesel engines”, says Lars Renström, President and CEO of the Alfa Laval Group. “The order also confirms our position as an innovative supplier of marine environmental solutions.”
The Alfa Laval PureNOx Water treatment system (WTS) is developed together with MAN Diesel & Turbo to be integrated in their Exhaust Gas Recirculation (EGR) process to reduce the NOx emissions from the main engines of the ships. The Alfa Laval WTS will clean the circulating scrubber water to protect the EGR system – and also clean the excess water formed during combustion – before it is being discharged overboard.
The International Maritime Organization’s (IMO) convention for the reduction of nitrogen oxides (NOx) will come into force in 2016 demanding NOx emissions to be reduced by 80 percent relative to 2000 levels – and it will affect newly built ships sailing in the special Emission Control Areas (ECAs) defined for NOx (as per today defined as large parts of the coastline of Canada and the US).
Did you know that… there are two main technological alternatives to meet the new requirements for nitrogen emissions: Selective Catalytic Reduction (SCR) and Exhaust Gas Recirculation (EGR)?
