PureCool. Exhaust gas cooling system by Alfa Laval.

 


If you choose LNG as fuel with the goal of a greener profile, the PureCool system will help you make the most of your choice. As part of iCER technology for second-generation WinGD X-DF engines, the PureCool system further reduces emissions by eliminating up to 50% of the methane slip. This unburned fuel, although only a fraction of the LNG consumed, may be the target of future legislation as IMO pursues ambitious climate goals.


With or without new regulations, selecting the iCER option with PureCool has a positive impact on your vessel’s bottom line. Operation with PureCool boosts fuel efficiency, saving 3% of the LNG consumption when operating in gas mode. If your vessel is an LNG carrier, this also means more money-making cargo can be delivered to the receiving terminal.

Cut methane slip and gain fuel efficiency !




1. Reduces methane slip by up to 50%.
2. Increases fuel efficiency by 3% when the engine is in gas mode.
3. Ensures maximum green benefit from the choice of LNG as fuel.
4. Minimizes LNG losses on LNG carriers, ensuring more delivered cargo.

How it works.
The PureCool system is a standalone cooling installation adjacent to the engine. It is the main component in the iCER option for WinGD X-DF engines, which improves combustion by cooling and recirculating up to 50% of the exhaust gas. The recirculation occurs through a low-pressure path with full turbocharger capacity, resulting in minimized methane slip and reduced fuel consumption.


The PureCool system’s primary component is the cooler tower, where circulation water is used to bring the exhaust gas from an inlet temperature of 230°C to an outlet temperature of 32°C. The circulation water is cooled in turn by a flow of seawater. Read the continue of the story by visiting the source bellow.
