ALFA LAVAL PURECOOL OFFERS A FURTHER MARINE ENVIRONMENTAL SOLUTION

ALFA LAVAL PURECOOL OFFERS A FURTHER MARINE ENVIRONMENTAL SOLUTION

Wednesday, November 18, 2020 

The latest addition to Alfa Lavals Pure Thinking portfolio, the PureCool system, is designed to reduce methane slip from LNG-fuelled engines, in advance of legislation to limit GHG emissions from gas-fuelled vessels.

Over 15 years ago, Alfa Laval introduced PureBallast and PureSOx well ahead of respective regulations, ensuring that customers had proven solutions when the time for compliance arrived. Similarly, PureCool targets methane slip, an as-yet unaddressed emission source; the small percentage of unburned methane fuel that escapes through the engine. Although no methane slip regulations currently exist, there is growing awareness of its climate impact.

Sameer Kalra, President, Alfa Laval Marine Division, said: “We recognise our responsibility, both to our customers and to generations to come. Alfa Laval is committed to meeting environmental challenges, which have grown more diverse and interconnected. Between our depth of experience and our involvement with many different onboard applications, we can take a comprehensive approach.”

According to Søren Hjorth Krarup, Business Unit President: “LNG is proving an important bridge fuel in the transition to a zero-carbon future. When combusted, LNG releases less CO2 than other fossil fuels. However, methane has a higher global warming potential than CO2, which makes the unburned fraction a concern. Regulations may or may not appear, but methane slip must be addressed if we are to reach a 50% reduction in marine greenhouse gas emissions by 2050.”

PureCool has been realised in partnership with engine developer WinGD, as the main component of iCER technology, an option for next-generation WinGD X-DF engines where exhaust gas is recirculated at low pressure. With PureCool as the vital cascade exhaust gas cooling system, iCER cuts methane slip by up to 50% ¬– while creating a 3% gain in fuel efficiency.

“Partnerships can bring the dramatic results needed to fight climate change,” said Kalra. “This is why Alfa Laval joined the Getting to Zero Coalition, and it is why we pursue joint projects with suppliers and research partners at the Alfa Laval Test and Training Centre. By pulling together across the industry, we can solve our planet’s problems while protecting – or even improving – vessel operations and economy.”

PureCool fits alongside Alfa Laval PureBallast (ballast water treatment), PureBilge (bilge water treatment), PureNOx LS & HS (NOx abatement), PureSOx (SO abatement) and PureVent (crankcase gas cleaning). However, it is the first Pure Thinking solution specifically for LNG and a new fuel era.

“Emission restrictions are influencing fuel selection, which in turn affects so much else on board,” said Kalra. “Getting to 2050 will require even more fuel choices, including biofuels, which we will soon be testing at the Alfa Laval Test and Training Centre. Whether customers select LNG or another option, we will help them get the most benefit from it – environmentally and otherwise. Every choice matters, and Alfa Laval can support every choice.”
