PureNOx Prime EGR water treatment system for operation with low-sulphur fuel Application High focus on emissions from ships is driving the stringent regulations for reducing NOx emissions beyond current levels (Tier II). Vessels with a keel-laid date on or after 1 January 2016 that travel in NOx Emission Control Areas (ECAs) will require engines certified for IMO Tier III. PureNOx Prime cleans the circulation water in an Exhaust Gas Recirculation (EGR) process operating on low-sulphur fuel. EGR is one of the solutions for compliance with Tier III NOx reduction demands and has the potential to be the NOx abatement frontrunner, especially as it requires very limited space in the engine room and has lower operating costs comparedwith other technology. Alfa Laval is collaborating with MAN Diesel and Turbo on the EGR process and has developed a PureNOx Prime as a dedicatedEGR water treatment system (WTS). Benefits • A well-established solution underpinned by more than 3 500 hours of real-world operation at sea • Saved space and installation expenses thanks to compact and simple installation • Increased uptime thanks to the possibility of operating EGR with reduced capacity during maintenance of PureNOx Prime • Reduced operating costs due to reduced EGR sludge g eneration volumes (lower onshore disposal costs) and power consumption when operating at engi

the engine control room is possible via the installation of a remote Alfa Laval Touch Control panel. The system can also be connected via computer bus communication (Modbus TCP, Modbus RTU, Profibus etc.) or hardwired signals directly into the ship’s integrated automation system. All functions and values are logged in the control system, which greatly enhances the potential for troubleshooting. The control system is prepared for connection to the vessel’s GPS receiver, with sync of the ship’s position and times for overboard discharges of cleaned water. The log data can be exported and...
